The description focuses on the molecular biology techniques (PCR, melt curve analysis) and the automated fluid handling system within the device to detect and identify specific nucleic acid targets. There is no mention of AI or ML being used for data interpretation, pattern recognition, or decision support beyond the automated interpretation of melt curve analysis based on predefined parameters.
No.
Explanation: The device is a diagnostic test (a multiplexed nucleic acid test) used to detect pathogens and antimicrobial resistance genes. It is explicitly stated that "The results of this test should not be used as for diagnosis, treatment, or other patient management decisions." This indicates it provides information to aid in diagnosis but does not directly treat or manage a condition, which is the definition of a therapeutic device.
Yes
The text states that the device "aids in the diagnosis of lower respiratory infection if used in conjunction with other clinical and epidemiological information." This clearly indicates its role in assisting the diagnostic process.
No
The device description explicitly states that the FilmArray Pneumonia Panel is used with the FilmArray 2.0 or FilmArray Torch systems, which are hardware instruments. The process involves loading a physical pouch containing reagents into the instrument, and the instrument performs physical actions (bladder inflation, seals, pistons, Peltier devices) to process the sample and perform PCR. While software is used to guide the user, interpret data, and provide results, the core functionality relies on dedicated hardware and physical reagents.
Based on the provided information, the FilmArray® Pneumonia Panel is indeed an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The document explicitly states the device is "intended for use with FilmArray® 2.0, or FilmArray® Torch systems for the simultaneous detection of multiple respiratory viral and bacterial nucleic acids, as well as select antimicrobial resistance genes, in sputum-like specimens... or bronchoalveolar lavage (BAL)-like specimens... obtained from individuals suspected of lower respiratory tract infection." This describes a test performed in vitro (outside the body) on biological specimens to provide information about a patient's health status.
- Purpose: The intended use further clarifies that the detection and identification of these nucleic acids "aids in the diagnosis of lower respiratory infection if used in conjunction with other clinical and epidemiological information." This directly aligns with the definition of an IVD, which is used to diagnose or aid in the diagnosis of a disease or condition.
- Device Description: The description details a system that processes biological samples (sputum-like and BAL-like specimens) using laboratory techniques (nucleic acid extraction, PCR, melt curve analysis) to generate results. This is characteristic of an IVD device.
- Regulatory Context: The mention of a "Predicate Device(s)" with a K number (DEN170047) strongly indicates that this device is undergoing or has undergone regulatory review as a medical device, specifically an IVD, by a regulatory body like the FDA in the US. K numbers are associated with 510(k) submissions for medical devices, including IVDs.
- Performance Studies: The detailed descriptions of clinical performance studies using patient specimens and comparisons to reference methods are standard requirements for demonstrating the analytical and clinical validity of an IVD.
Therefore, the FilmArray® Pneumonia Panel fits the definition and characteristics of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The FilmArray® Pneumonia Panel is a multiplexed nucleic acid test intended for use with FilmArray® 2.0, or FilmArray® Torch systems for the simultaneous detection of multiple respiratory viral and bacterial nucleic acids, as well as select antimicrobial resistance genes, in sputum-like specimens (induced or expectorated sputum, or endotracheal aspirates) or bronchoalveolar lavage (BAL)-like specimens (BAL or mini-BAL) obtained from individuals suspected of lower respiratory tract infection.
The following bacteria are reported semi-quantitatively with bins representing approximately 10^4 10^5, 10^6, or ≥10^7 genomic copies of bacterial nucleic acid per milliliter (copies/mL) of specimen, to aid in estimating relative abundance of nucleic acid from these common bacteria within a specimen:

- Respiratory Syncytial Virus
Antimicrobial Resistance Genes - CTX-M
- IMP
- КРС
- NDM
- · OXA-48-like
- VIM
- · mecA/C and MREJ
The detection and identification of specific viral and bacterial nucleic acids, as well as the estimation of relative abundance of nucleic acid from common bacterial analytes, within specimens collected from individuals exhibiting signs and/or symptoms of a respiratory infection, aids in the diagnosis of lower respiratory infection if used in conjunction with other clinical and epidemiological information. The results of this test should not be used as for diagnosis, treatment, or other patient management decisions.
Negative results in the setting of a respiratory illness may be due to infection with pathogens that are not detected by this test, pathogens below the limit of detection, or in the case of bacterial analytes, present at levels below the lowest reported 10^4 copies/mL bin. Detection of analytes does not rule out co-infection with other organisms: the agent(s) detected by the Film Array Pneumonia Panel may not be the definite cause of disease. Additional laboratory testing (e.g. bacterial and viral culture, immunofluorescence, and radiography) may be necessary when evaluating a patient with possible lower respiratory tract infection.
Detection of bacterial nucleic acid may be indicative of colonizing or normal respiratory flora and may not indicate the causative agent of pneumonia. Semi-quantitative bin (copies/mL) results generated by the FilmArray Pneumonia Panel are not equivalent to CFU/mL and do not consistently correlate with the quantity of bacterial analytes compared to CFU/mL. For specimens with multiple bacteria detected, the relative abundance of nucleic acids (copies/mL) may not correlate with the relative abundance of bacteria as determined by culture (CFU/mL). Clinical correlation is advised to determine significance of semi-quantitative bin (copies/mL) for clinical management.
The antimicrobial resistance gene detected may or may not be associated with the agent(s) responsible for disease. Negative results for these antimicrobial resistance gene assays do not indicate susceptibility to corresponding classes of antimicrobials, as multiple mechanisms of antimicrobial resistance exist.
Antimicrobial resistance can occur via multiple mechanisms. A "Not Detected" result for a genetic marker of antimicrobial resistance does not indicate susceptibility to associated antimicrobial drugs or drug classes. A "Detected" result for a genetic marker of antimicrobial resistance cannot be definitively linked to the microorganism(s) detected. Culture is required to obtain isolates for antimicrobial susceptibility testing, and FilmArray Pneumonia Panel results should be used in conjunction with culture results for determination of bacterial susceptibility or resistance.
Due to the genetic similarity between human rhinovirus and enterovirus, the test cannot reliably differentiate them. A positive Rhinovirus/Enterovirus result should be followed up using an alternate method (e.g., cell culture or sequence analysis) if differentiation is required.
Culture is required to identify pathogens not detected by the FilmArray Pneumonia Panel, to further speciate analytes in genus, complex, or group results if desired, to identify bacterial pathogens present below the 10^4 copies/mL bin if desired, and for antimicrobial susceptibility testing.

Device Description
The FilmArray Pneumonia Panel is designed to simultaneously identify 26 potential pathogens of lower respiratory tract infection (LRTI) and associated antimicrobial resistance (AMR) genes from a sputumlike (induced and expectorated sputum as well as endotracheal aspirate, ETA) or bronchoalveolar lavage (BAL)-like (BAL and mini-BAL) specimens obtained from individuals with signs and/or symptoms of lower respiratory tract infection in a time (~1 hour) that allows the test results to be used in determining appropriate patient treatment and management. FilmArray Pneumonia Panel is compatible with BioFire Diagnostics' (BioFire) PCR-based in vitro diagnostic FilmArray 2.0, and FilmArray Torch systems for infectious disease testing. A specific software module (i.e. FilmArray Pneumonia Panel pouch module) is used to perform FilmArray Pneumonia Panel testing on these systems.

A test is initiated by loading Hydration Solution into one port of the FilmArray pouch and a sputum-like or BAL-like sample mixed with the provided Sample Buffer into the other port of the FilmArray Pneumonia Panel pouch and placing it in a FilmArray instrument. The pouch contains all of the reagents required for specimen testing and analysis in a freeze-dried format; the addition of Hydration Solution and Sample/Buffer Mix rehydrates the reagents. After the pouch is prepared, the FilmArray Software guides the user though the steps of placing the instrument, scanning the pouch barcode, entering the sample identification, and initiating the run.
The FilmArray instrument contains a coordinated system of inflatable bladders and seal points, which act on the pouch to control the movement of liquid between the pouch blisters. When a bladder is inflated over a reagent blister, it forces liquid from the blister into connecting channels. Alternatively, when a seal is placed over a connecting channel it acts as a valve to open or close a channel. In addition, electronically-controlled pneumatic pistons are positioned over multiple plungers in order to deliver the rehydrated reagents into the blisters at the appropriate times. Two Peltier devices control heating and cooling of the pouch to drive the PCR reactions and the melt curve analysis.
Nucleic acid extraction occurs within the FilmArray pouch using mechanical and chemical lysis followed by purification using standard magnetic bead technology. After extracting and purifying nucleic acids from the unprocessed sample, the FilmArray performs a nested multiplex PCR that is executed in two stages. During the filmArray performs a single, large volume, highly multiplexed reverse transcription PCR (rt-PCR) reaction. The products from first stage PCR are then diluted and combined with a fresh, primer-free master mix and a fluorescent double stranded DNA binding dye (LC Green® Plus, BioFire Diagnostics). The solution is then distributed to each well of the array. Array wells contain sets of primers designed specifically to amplify sequences internal to the PCR products generated during the first stage PCR reaction. The 2nd stage PCR, or nested PCR, is performed in singleplex fashion in each well of the array. At the conclusion of the 2nd stage PCR, the array is interrogated by melt curve analysis for the detection of signature amplicons denoting the presence of specific targets. A digital camera placed in front of the 2nd stage PCR captures fluorescent images of the PCR reactions and software interprets the data.
The FilmArray Software automatically interprets the results of each DNA melt curve analysis and combines the data with the results of the internal pouch controls to provide a test result for each organism on the panel.

Description of the test set, sample size, data source, and annotation protocol
The clinical performance of the FilmArray Pneumonia Panel was established during a multi-center study conducted at eight geographically distinct U.S. study sites from October 2016 to July 2017. A total of 904 residual BAL (821 BAL and 83 mini-BAL) and 925 residual sputum ( 478 sputum and 447 ETA) specimens were acquired for the prospective clinical study. FilmArray Pneumonia Panel performance in BAL and mini-BAL was similar, as was performance in sputum and ETA; therefore these sample types are not stratified further in performance tables. A total of 58 BAL and 89 sputum specimens were excluded from the final data analysis. The most common reasons for specimen exclusion for both specimen types was reference culture unable to be performed, the specimen was found to not meet the inclusion criteria after the specimen had been enrolled, or the study site was unable to complete the Case Report Form (CRF). The final data set consisted of 846 BAL and 836 sputum specimens.
All specimens were evaluated with the FilmArray Pneumonia Panel at clinical study sites. Refrigerated specimen aliquots were sent to a central reference laboratory for quantitative reference culture (qRefCx) and frozen specimen aliquots were also sent to BioFire for evaluation by polymerase chain reaction (PCR)/sequencing-based comparator methods.
The reference methods used in this study were as follows:
Bacterial analytes were compared to qRefCx to evaluate sensitivity and the method was considered positive for the presence of the organism of interest if it was recovered in culture and enumerated at a level of 3162 (10^3.5) CFU/mL or greater.
Bacterial analytes were also evaluated by comparison to a single PCR assay for the organism of interest followed by a quantitative molecular assay that included sequencing (qMol) to assess FilmArray bin reporting performance. Atypical bacteria and viruses were compared to two conventional PCR assays followed by bidirectional sequencing. For specimens with an applicable bacteria detected by FilmArray, AMR genes were compared to a single PCR assay (from the specimen) followed by sequencing. A specimen was considered to be positive for an analyte if bi-directional sequencing data meeting predefined quality acceptance criteria matched organism-specific sequences deposited in the NCBI GenBank database (www.ncbi.nlm.nih.gov) with acceptable E-values. When two PCR comparator assays were used, any specimen that tested negative by both of the comparator assays was considered Negative.
Positive Percent Agreement (PPA) or Sensitivity for each analyte was calculated as 100% x (TP + FN)). True positive (TP) indicates that both the FilmArray Pneumonia Panel and the comparator method had a positive result for this specific analyte, and false negative (FN) indicates that the FilmArray Pneumonia Panel result was negative while the comparator result was positive. Negative Percent Agreement (NPA) or Specificity was calculated as 100% x (TN + FP)). True negative (TN) indicates that both the FilmArray Pneumonia Panel and the comparator method had negative results, and a false positive (FP) indicates that the FilmArray Pneumonia Panel result was positive but the comparator result was negative. The exact binomial two-sided 95% confidence interval was calculated. Samples for which false positive and/or false negative results (i.e., discrepant results) were obtained when comparing the FilmArray Pneumonia Panel results to the comparator method results were further investigated. The discrepancy investigations were primarily performed as follows: for discrepancies between the Pneumonia Panel and reference culture for bacterial analytes, discrepancies were first examined to see if qRefCx or FilmArray had observed the analyte but reported it as "negative" or "Not Detected" because it was below the detection threshold. If this did not resolve the discrepancy, the results of qMol testing were considered. And if these methods still did not resolve the discrepancy, it was then investigated in the same manner as other analytes that used molecular comparator (i.e. using multiple additional molecular assays followed by sequence analysis). The results of SOC testing were also considered.

Device Name FilmArray Pneumonia Panel
Indications for Use (Describe)
The FilmArray® Pneumonia Panel is a multiplexed nucleic acid test intended for use with FilmArray® 2.0, or FilmArray® Torch systems for the simultaneous detection of multiple respiratory viral and bacterial nucleic acids, as well as select antimicrobial resistance genes, in sputum-like specimens (induced or expectorated sputum, or endotracheal aspirates) or bronchoalveolar lavage (BAL)-like specimens (BAL or mini-BAL) obtained from individuals suspected of lower respiratory tract infection.
The following bacteria are reported semi-quantitatively with bins representing approximately 10°4 10°5, 10°6, or ≥10°7 genomic copies of bacterial nucleic acid per milliliter (copies/mL) of specimen, to aid in estimating relative abundance of nucleic acid from these common bacteria within a specimen:

The detection and identification of specific viral and bacterial nucleic acids, as well as the estimation of relative abundance of nucleic acid from common bacterial analytes, within specimens collected from individuals exhibiting signs and/or symptoms of a respiratory infection, aids in the diagnosis of lower respiratory infection if used in conjunction with other clinical and epidemiological information. The results of this test should not be used as for diagnosis, treatment, or other patient management decisions.
Negative results in the setting of a respiratory illness may be due to infection with pathogens that are not detected by this test, pathogens below the limit of detection, or in the case of bacterial analytes, present at levels below the lowest reported 10°4 copies/mL bin. Detection of analytes does not rule out co-infection with other organisms: the agent(s) detected by the Film Array Pneumonia Panel may not be the definite cause of disease. Additional laboratory testing (e.g. bacterial and viral culture, immunofluorescence, and radiography) may be necessary when evaluating a patient with possible lower respiratory tract infection.
Detection of bacterial nucleic acid may be indicative of colonizing or normal respiratory flora and may not indicate the causative agent of pneumonia. Semi-quantitative bin (copies/mL) results generated by the FilmArray Pneumonia Panel are not equivalent to CFU/mL and do not consistently correlate with the quantity of bacterial analytes compared to CFU/mL. For specimens with multiple bacteria detected, the relative abundance of nucleic acids (copies/mL) may not correlate with the relative abundance of bacteria as determined by culture (CFU/mL). Clinical correlation is advised to determine significance of semi-quantitative bin (copies/mL) for clinical management.
The antimicrobial resistance gene detected may or may not be associated with the agent(s) responsible for disease. Negative results for these antimicrobial resistance gene assays do not indicate susceptibility to corresponding classes of antimicrobials, as multiple mechanisms of antimicrobial resistance exist.
Antimicrobial resistance can occur via multiple mechanisms. A "Not Detected" result for a genetic marker of antimicrobial resistance does not indicate susceptibility to associated antimicrobial drugs or drug classes. A "Detected" result for a genetic marker of antimicrobial resistance cannot be definitively linked to the microorganism(s) detected. Culture is required to obtain isolates for antimicrobial susceptibility testing, and FilmArray Pneumonia Panel results should be used in conjunction with culture results for determination of bacterial susceptibility or resistance.
Due to the genetic similarity between human rhinovirus and enterovirus, the test cannot reliably differentiate them. A positive Rhinovirus/Enterovirus result should be followed up using an alternate method (e.g., cell culture or sequence analysis) if differentiation is required.
Culture is required to identify pathogens not detected by the FilmArray Pneumonia Panel, to further speciate analytes in genus, complex, or group results if desired, to identify bacterial pathogens present below the 10°4 copies/mL bin if desired, and for antimicrobial susceptibility testing.

Device Description:
The FilmArray Pneumonia Panel is designed to simultaneously identify 26 potential pathogens of lower respiratory tract infection (LRTI) and associated antimicrobial resistance (AMR) genes from a sputumlike (induced and expectorated sputum as well as endotracheal aspirate, ETA) or bronchoalveolar lavage (BAL)-like (BAL and mini-BAL) specimens obtained from individuals with signs and/or symptoms of lower respiratory tract infection in a time (~1 hour) that allows the test results to be used in determining appropriate patient treatment and management. FilmArray Pneumonia Panel is compatible with BioFire Diagnostics' (BioFire) PCR-based in vitro diagnostic FilmArray 2.0, and FilmArray Torch systems for infectious disease testing. A specific software module (i.e. FilmArray Pneumonia Panel pouch module) is used to perform FilmArray Pneumonia Panel testing on these systems.

A test is initiated by loading Hydration Solution into one port of the FilmArray pouch and a sputum-like or BAL-like sample mixed with the provided Sample Buffer into the other port of the FilmArray Pneumonia Panel pouch and placing it in a FilmArray instrument. The pouch contains all of the reagents
9
required for specimen testing and analysis in a freeze-dried format; the addition of Hydration Solution and Sample/Buffer Mix rehydrates the reagents. After the pouch is prepared, the FilmArray Software guides the user though the steps of placing the instrument, scanning the pouch barcode, entering the sample identification, and initiating the run.
The FilmArray instrument contains a coordinated system of inflatable bladders and seal points, which act on the pouch to control the movement of liquid between the pouch blisters. When a bladder is inflated over a reagent blister, it forces liquid from the blister into connecting channels. Alternatively, when a seal is placed over a connecting channel it acts as a valve to open or close a channel. In addition, electronically-controlled pneumatic pistons are positioned over multiple plungers in order to deliver the rehydrated reagents into the blisters at the appropriate times. Two Peltier devices control heating and cooling of the pouch to drive the PCR reactions and the melt curve analysis.
Nucleic acid extraction occurs within the FilmArray pouch using mechanical and chemical lysis followed by purification using standard magnetic bead technology. After extracting and purifying nucleic acids from the unprocessed sample, the FilmArray performs a nested multiplex PCR that is executed in two stages. During the filmArray performs a single, large volume, highly multiplexed reverse transcription PCR (rt-PCR) reaction. The products from first stage PCR are then diluted and combined with a fresh, primer-free master mix and a fluorescent double stranded DNA binding dye (LC Green® Plus, BioFire Diagnostics). The solution is then distributed to each well of the array. Array wells contain sets of primers designed specifically to amplify sequences internal to the PCR products generated during the first stage PCR reaction. The 2nd stage PCR, or nested PCR, is performed in singleplex fashion in each well of the array. At the conclusion of the 2nd stage PCR, the array is interrogated by melt curve analysis for the detection of signature amplicons denoting the presence of specific targets. A digital camera placed in front of the 2nd stage PCR captures fluorescent images of the PCR reactions and software interprets the data.
The FilmArray Software automatically interprets the results of each DNA melt curve analysis and combines the data with the results of the internal pouch controls to provide a test result for each organism on the panel.
Substantial Equivalence:
The FilmArray Pneumonia Panel is substantially equivalent to the Curetis Unyvero LRT Application (DEN170047), which was recently cleared on April 03, 2018 and determined to be a Class II device under the classification product code QBH.
Table 1 compares the FilmArray Pneumonia Panel to the Curetis Unyvero LRT Application and outlines the similarities and differences between the two systems.

Summary of Performance Data
Clinical Performance
The clinical performance of the FilmArray Pneumonia Panel was established during a multi-center study conducted at eight geographically distinct U.S. study sites from October 2016 to July 2017. A total of 904 residual BAL (821 BAL and 83 mini-BAL) and 925 residual sputum ( 478 sputum and 447 ETA) specimens were acquired for the prospective clinical study. FilmArray Pneumonia Panel performance in BAL and mini-BAL was similar, as was performance in sputum and ETA; therefore these sample types are not stratified further in performance tables. A total of 58 BAL and 89 sputum specimens were excluded from the final data analysis. The most common reasons for specimen exclusion for both specimen types was reference culture unable to be performed, the specimen was found to not meet the inclusion criteria after the specimen had been enrolled, or the study site was unable to complete the Case Report Form (CRF). The final data set consisted of 846 BAL and 836 sputum specimens. Table 2 and Table 3 provide a summary of demographic information for the specimens included in the prospective study.

All specimens were evaluated with the FilmArray Pneumonia Panel at clinical study sites. Refrigerated specimen aliquots were sent to a central reference laboratory for quantitative reference culture (qRefCx) and frozen specimen aliquots were also sent to BioFire for evaluation by polymerase chain reaction (PCR)/sequencing-based comparator methods.
The reference methods used in this study were as follows:
Bacterial analytes were compared to qRefCx to evaluate sensitivity and the method was considered positive for the presence of the organism of interest if it was recovered in culture and enumerated at a level of 3162 (10^3.5) CFU/mL or greater.
Bacterial analytes were also evaluated by comparison to a single PCR assay for the organism of interest followed by a quantitative molecular assay that included sequencing (qMol) to assess FilmArray bin reporting performance. Atypical bacteria and viruses were compared to two conventional PCR assays followed by bidirectional sequencing. For specimens with an applicable bacteria detected by FilmArray, AMR genes were compared to a single PCR assay (from the specimen) followed by sequencing. A specimen was considered to be positive for an analyte if bi-directional sequencing data meeting predefined quality acceptance criteria matched organism-specific sequences deposited in the NCBI GenBank database (www.ncbi.nlm.nih.gov) with acceptable E-values. When two PCR comparator assays were used, any specimen that tested negative by both of the comparator assays was considered Negative.
Positive Percent Agreement (PPA) or Sensitivity for each analyte was calculated as 100% x (TP + FN)). True positive (TP) indicates that both the FilmArray Pneumonia Panel and the comparator method had a positive result for this specific analyte, and false negative (FN) indicates that the FilmArray Pneumonia Panel result was negative while the comparator result was positive. Negative Percent Agreement (NPA) or Specificity was calculated as 100% x (TN + FP)). True negative (TN) indicates that both the FilmArray Pneumonia Panel and the comparator method had negative results, and a false positive (FP) indicates that the FilmArray Pneumonia Panel result was positive but the comparator result was negative. The exact binomial two-sided 95% confidence interval was calculated. Samples for which false positive and/or false negative results (i.e., discrepant results) were obtained when comparing the FilmArray Pneumonia Panel results to the comparator method results were further investigated. The discrepancy investigations were primarily performed as follows: for discrepancies between the Pneumonia Panel and reference culture for bacterial analytes, discrepancies were first examined to see if qRefCx or FilmArray had observed the analyte but reported it as "negative" or "Not Detected" because it was below the detection threshold. If this did not resolve the discrepancy, the results of qMol testing were considered. And if these methods still did not resolve the discrepancy, it was then investigated in the same manner as other analytes that used molecular comparator (i.e. using multiple additional molecular assays followed by sequence analysis). The results of SOC testing were also considered. The prospective clinical study results are summarized in Table 5 for BAL and sputum specimens, respectively.

Testing of Contrived Specimens
A prospective clinical evaluation of the FilmArray Pneumonia Panel was performed during the 2016-2017 respiratory infection season at several geographically diverse clinical laboratories. Over 1600 specimens were analyzed from subjects whose specimens were submitted for microbial evaluation of lower respiratory tract pathogens. In the prospective study, some analytes were of insufficient prevalence to adequately demonstrate system performance and additional archived, preselected positive specimens containing rare analytes were also tested. Several analytes were so rare that both prospective and archived testing efforts were insufficient to demonstrate system performance. In this study, contrived clinical specimens were created to evaluate the sensitivity and specificity of the FilmArray Pneumonia Panel assays for these rare analytes (Table 39Error! Reference source not found.).

Contrived specimens (N=1125) were spiked using residual clinical samples that were pre-screened with the FilmArray Pneumonia Panel and found to be negative for the analytes of interest. Specimens were spiked with a variety of different isolates/strains for each organism at concentrations spanning observed ranges in clinical specimens. Different isolates of organisms were used in analytical testing when possible. Samples positive for one analyte served as negatives for other analytes.
For the majority of analytes reported qualitatively, at least 25 of the contrived positive specimens had analyte concentrations at 2 × the limit of detection (LoD), while the remaining specimens were tested at additional concentrations that spanned clinically observed ranges. The "clinically observed range" was based on data from previous FilmArray Pneumonia Panel positive test results (e.g. observations from the prospective or archived studies). If a clinically observed range could not be determined for a particular analyte, specimens were spiked at various factors of LoD. If the stock concentration of organism did not allow for spiking at the highest level, the highest achievable level was used. For bacteria reported with binned values, specimens were spiked at various concentrations starting just below and then spanning the reported levels (i.e. 10^3 to ≥10^7 copies per milliliter (mL)).
Specimens were prepared and randomized at BioFire such that the analyte status of each contrived specimen was unknown to the users performing the testing. BAL and sputum specimens were analyzed separately; however, the preparation and testing for both matrices were identical. Contrived specimens
37
were frozen, then distributed to prospective study sites and tested according to the prospective clinical study protocol alongside clinical (non-contrived) specimens.
The positive percent agreement (PPA) and negative percent (NPA) for the FilmArray Pneumonia Panel assays were determined using standard binomial sampling statistics. In this study, a success was defined as agreement between the known composition of the contrived specimen and the FilmArray Pneumonia Panel result; i.e., a positive FilmArray Pneumonia Panel result for spiked samples (True Positive, TP) and a negative FilmArray Pneumonia Panel result for un-spiked samples (True Negative, TN).
The results of the 1125 specimens tested in this study are summarized in Error! Reference source not found. for BAL and Error! Reference source not found. for sputum below.
The majority of analytes in both specimen types met the performance goals of 90% PPA with an 80% lower bound of the 95% Cl and 98% NPA with a 95% lower bound of the 95% CI. The exceptions being influenza A spiked into BAL and Klebsiella aerogenes spiked into BAL and sputum. Influenza A spiked in BAL demonstrated 86% PPA in part due to two missed detections at 0.2 × LoD and two additional missed detections at 2 × LoD from a strain that may have been under-quantified. However, FilmArray performance goals for influenza A in BAL were achieved in the archived study. Klebsiella aerogenes spiked in both sample types demonstrated 85.5% PPA in part due to five missed detections in BAL and four missed detections in sputum at a range of concentrations from a Klebsiella aerogenes strain that demonstrated poor reactivity with the FilmArray Pneumonia Panel.
Samples spiked with bacterial analytes just below the 10% copies/mL binned value (i.e., near 1.00E+03), and samples spiked with other analytes below their LoD (i.e., near 0.2 × LoD), produced the expected unreliable detection.

Testing of Polymicrobial Contrived Specimens
Additionally, two sets of individual BAL (N=60) and sputum (N=60) specimens were multi-spiked with randomized low, medium and high relative concentrations of either A. baumannii, E. cloacae, and E. coli or K. oxytoca, P. mirabilis, and S. marcescens. As shown in Table 43, the majority of the spiked organisms were reported at the expected relative low, medium, or high bin level by the
39
FilmArray Pneumonia Panel. In four BAL specimens, E. cloacae was intended to be spiked at a medium level but was reported in a in a high (≥10^7) bin. Also, one specimen spiked with a high level of P. mirabilis was not detected (i.e. a false negative result for P. mirabilis).

Selected Analytical Studies
Limit of Detection
A limit of detection (LoD) was established for atypical bacteria and viruses detected by the FilmArray Pneumonia Panel. LoD was estimated by testing dilutions of contrived BAL or sputum samples containing known concentrations of organisms. Confirmation of LoD was achieved by testing at least 20 replicates per samples type on FilmArray 2.0 and FilmArray Torch systems (60 replicates total per sample type). LoD concentration was confirmed when the analyte was detected in at least 95% of the replicates tested.
The confirmed LoD for each atypical bacterium or virus (including a LoD for more than one isolate of the more genetically diverse viruses) is listed in Table 44Error! Reference source not found.. LoD concentration is based on quantification of each culture in viable units (TCID50/mL or CFU/mL) and a
40
corresponding molecular LoD concentration (DNA or RNA copies/mL) is provided based on quantitative real-time or digital PCR.

d No cultured isolates of Coronavirus HKU1 were available for testing.
Note: LoD concentrations of the cultured viruses and the obligate intracellular atypical bacteria (C. pneumoniae and M. pneumoniae) are provided in units of TCID50 (50% Tissue Culture Infectious Dose). TCIDso is an indirect measure of viral or bacterial concentration based on infectivity and cvtotoxicity and will therefore vary considerably depending on technique and methodology (including cell type, culture media and conditions, cytotoxicity of the virus, etc.). It is not appropriate to make determinations on relative sensitivity of different molecular assays for detection of viruses and bacteria based on LoD values measured in TCID50/mL. Concentrations are also presented in copies/mL based upon independent quantitative PCR assays (qPCR) or digital PCR. Note that the accuracy of qPCR assays may also be affected by assay conditions, the standard reference material, and sequence variance between strains.
No assay-specific LoD concentrations were determined for the bacterial analytes. For bacteria, the FilmArray Pneumonia Panel reports a Detected result when the estimated bacterial nucleic acid abundance is ≥10^3.5 copies/mL, and the panel reports a Not Detected result if there is no amplification or the estimated bacterial nucleic acid abundance is 0.95) and estimates of nucleic acid abundance and corresponding bin results were determined to be accurate within 0.5-log10 copies/mL when compared to a copies/mL input concentration determined by digital PCR.No assay-specific LoD concentrations were determined for the antimicrobial resistance (AMR) gene assays. AMR genes are reported as Detected when an applicable bacterium is Detected and the assay for the AMR gene is positive AMR gene assay results were observed in ≥95% of 90 replicates when the applicable bacterium was tested at a concentration ≥10^3.5 copies/mL in the precision evaluation (see Precision (Reproducibility) below).
Inclusivitv
Analytical reactivity of FilmArray Pneumonia Panel assays was evaluated via a combination of empirical (wet) testing and in silico analysis of sequences available in public databases. Testing was performed on a collection of more than 350 genetically diverse viruses, bacteria, and antimicrobial resistance genes. The tested isolates represent relevant species, strains, serotypes, or genotypes as well as temporal and geographic diversity for each of the panel analytes. Each isolate was tested in triplicate at concentrations near LoD or the lowest reportable level for the analyte. In silico analysis of sequence data was also used to make predictions of assay reactivity for less common strains or serotypes and AMR gene types that were not tested but that may be detected by the FilmArray Pneumonia Panel assays.
Atypical bacteria and viruses were tested and detected at concentrations within 3× LoD (Table 46Error! Reference source not found. - Table 56Error! Reference source not found.). Bacteria were tested at a concentration of 1.0E+04 copies/mL (based on digital PCR of a single-copy gene in the bacterial chromosome) and the majority of isolates (94.4%) were detected with the expected bin result (Table 57Error! Reference source not found. - Table 71Error! Reference source not found.) and when the bacterium was detected, the appropriate AMR gene(s) were also detected (Table 72Error! Reference source not found. - Table 79Error! Reference source not found.).
Limitations on assay reactivity (based on wet testing observations) with specific viral and bacterial isolates or sequences and AMR gene types or sequences are noted in Table 45Error! Reference source not found.. Most limitations are associated with single-base sequence variants under one or more assay primers. Additional predicted limitations on reativity based on in-silico sequence analysis are provided in the footnotes and analyte-specific tables below.

Analytical Specificity (Cross-Reactivity and Exclusivity)
There is a risk of false positive results due to non-specific amplification and/or cross-reactivity with organisms found in the respiratory tract. The potential for non-specific amplification and detection by BioFire Diagnostics 510(k) FilmArray Pneumonia Panel
54
the FilmArray Pneumonia Panel assays was evaluated by in silico analyses of available sequences and by empirical (wet) testing of high concentrations of organisms in contrived samples. The observed and predicted cross-reactivities for organisms closely related to those detected by the panel and unrelated organisms that may be present in lower respiratory specimens are summarized in Table 80. Erroneous results due to cross-reactivity with organisms that were not evaluated or new variant sequences that emerge is also possible.
On-panel organisms were tested to assess the potential for intra-panel cross-reactivity (Table 81Error! Reference source not found.). Off-panel organisms included species of the same genus or otherwise genetically related to organisms detected by the panel, as well as normal flora and pathogens that may be present in sputum-like and BAL-like specimens (Table 82). Antimicrobial resistance genes were also evaluated in conjunction with on and off panel host organisms.
The final concentration of analyte in the sample (typically >1.0E+07 CFU/mL for bacteria and fungi and >1.0E+05 TCID30/mL for viruses) represented levels ~100 - 100,000 fold higher than the LoD or lowest reportable level of the FilmArray Pneumonia Panel assays.

Evaluation of the reproducibility of Detected results for atypical bacteria and viruses included samples containing combinations of five different analytes, at Negative, Low Positive
57
(1×LoD), and Moderate Positive (3×LoD) concentrations. Negative results were obtained from samples that were not spiked with the analyte (see evaluation of precision for bacterial analytes below).
A summary of results (percent (%) agreement with the expected Detected or Not Detected result) for atypical bacteria and viruses (by site and system) is provided in Table 83Error! Reference source not found..

Table 83. Reproducibility of FilmArray Pneumonia Panel Atypical Bacteria and Virus Results
58
Precision for bacterial analytes was measured at each concentration as 1) precision of bin results and 2) reproducibility of analyte detection. When a sample containing one or more bacteria is tested repeatedly, the precision of the bin results (probability that each replicate will receive the same bin result) will vary based on the concentration of nucleic acid measured and the relation of that concentration to the limits of each bin. Bin precision may be as low as 50% for values at a bin limit and precision will increase (up to 90% or higher) as the distance of the measured value from a bin limit increases. The precision of FilmArray Pneumonia Panel bin results will follow the model illustrated in Figure 1Error! Reference source not found.:
-
90% at a bin center (Scenario 1)
- ~60 90% between a bin limit and bin center (Scenario 2) ●
- ~50% at bin limits (Scenario 3)
Image /page/58/Figure/5 description: The image shows a graph of the probability of a reported bin result versus the measured value. The graph shows the probability of reporting a bin result for different measured values, with the bins labeled as 'Not Detected', '10^4', '10^5', '10^6', and '≥10^7'. Below the graph, there are three scenarios that show the mean measured value for different bins. Scenario 1 shows a mean measured value of 10^5.0 with a probability of ≥90%, scenario 2 shows a mean measured value of 10^5.25 with probabilities of ~75% and ~25%, and scenario 3 shows a mean measured value of 10^5.5 with probabilities of ~50% and ~50%.
Figure 1. Model for Precision of FilmArray Pneumonia Panel Bin Results
Top: The probability (0.0 – 1.0) of the same bin results for each replicate tested varies based on proximity of the measured value to a bin limit.
Bottom: Expected distribution of bin results at different mean measured values.
Samples containing bacteria and corresponding antimicrobial resistance (AMR) genes were tested at six different concentrations over the reportable range and below. A summary of the bin precision (percent (%) of replicates reported in each bin) and the reproducibility of detection is shown at each concentration tested in Table 84Error!

Interference
Potentially interfering substances that could be present in BAL-like or sputum-like specimens or that may be introduced during specimen collection and testing were evaluated for their effect on FilmArray Pneumonia Panel performance. Substances included endogenous substances that may be found in specimens at normal or elevated levels (e.g. blood, mucus/mucin, human genomic DNA), various commensal or infectious microorganisms, medications, a variety of sample processing substances and substances used to clean, decontaminate, or disinfect work areas. The performance of the FilmArray Pneumonia Panel has not been established with all potentially interfering medications for the treatment of lower respiratory tract infections. The effect of interfering substances has only been evaluated for those listed in Table 86. Interference from substances that were not evaluated could lead to erroneous results.
Each substance was added to contrived samples containing representative qualitatively reported organisms and representative organisms with bin reporting. Qualitatively reported organisms were at concentrations near (2-3×) LoD and those with bin reporting were present at 4.0 log10 (copies/mL) (e.g. in the lowest reported bin). The concentration of substance added to the samples (Table 86) was equal to or greater than the highest level expected to be in BAL-like or Sputum-like specimens.
Four of the evaluated substances were found to interfere with the FilmArray Pneumonia Panel to report accurate analyte results; Bleach, MycoPrep, 2% NaOH, and 5% Oxalic acid. Each of these substances contain chemicals known to react with nucleic acids, altering their chemical structure. The interference observed was related to the inability to detect the chemically modified nucleic acids. Treatment of specimens with these substances prior to FilmArray Pneumonia Panel testing may result in loss of analyte detection, therefore samples that have been in contact with these substances should not be tested using the FilmArray Pneumonia Panel. None of the other substances tested were shown to interfere with the FilmArray Pneumonia Panel results, however, testing of specimens that have been centrifuged or pre-treated by addition of enzyme, media, mucolytic agent, or decontaminating substances is not recommended..
