The Alinity m STI Assay is an in vitro polymerase chain reaction (PCR) assay for use with the automated Alinity m System for the direct, qualitative detection and differentiation of ribosomal RNA from Chlamydia trachomatis (CT), DNA from Neisseria gonorrhoeae (NG), ribosomal RNA from Trichomonas vaginalis (TV), and ribosomal RNA from Mycoplasma genitalium (MG), to aid in the diagnosis of disease(s) caused by infection from these organisms. The assay may be used to test the following specimens from symptomatic and asymptomatic individuals for the following analytes:
CT: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, male urine, oropharyngeal swabs, and rectal swabs
NG: vaginal swabs (clinician-collected and self-collected in a clinical setting). endocervical swabs, gynecological specimens in ThinPrep PreservCyt Solution, male urine, oropharyngeal swabs, and rectal swabs
TV: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, gynecological specimens in ThinPrep PreservCyt Solution, female urine, and male urine
MG: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, and male urine
A vaginal swab (self-collected or clinician-collected) is the preferred specimen type for MG testing in females due to higher clinical sensitivity compared to endocervical swabs. If endocervical swab specimens test negative, testing with a vaginal swab may be indicated if M. genitalium infection is suspected.
The Alinity m STI Assay is a real time polymerase chain reaction (PCR) assay for the amplification and detection of Chlamydia trachomatis (CT) ribosomal RNA sequences, Neisseria gonorrhea (NG) genomic DNA sequences, Trichomonas vaginalis (TV) ribosomal RNA sequences, Mycoplasma genitalium (MG) ribosomal RNA sequences, and human genomic DNA sequences. The assay can be used with endocervical swab specimens, vaginal swab specimens, male and female urine specimens, gynecological specimens in ThinPrep® PreservCyt® Solution, oropharyngeal swab specimens, and rectal swab specimens. Endocervical swab, vaginal swab, oropharyngeal swab, rectal swab and urine specimens are collected with the Alinity m multi-Collect Specimen Collection Kit. PreservCyt Solution specimens are transferred to an Alinity m Transport Tube for processing on the Alinity m System.
The steps of the Alinity m STI Assay consist of sample preparation, RT-PCR assembly, amplification/detection, and result calculation and reporting. All stages of the Alinity m STI Assay procedure are executed automatically by the Alinity m System. No intermediate processing or transfer steps are performed by the user. The Alinity m System is designed to be a random-access analyzer that can perform the Alinity m STI Assay in parallel with other Alinity m assays on the same instrument.
The Alinity m STI Assay requires two separate assay specific kits as follows:
- . Alinity m STI AMP Kit, List No. 09N17-095 consisting of multi-well amplification plates containing lyophilized, unit-dose PCR amplification/detection reagents and multi-well activator plates containing liquid, unit-dose activation reagents (MgCl2, TMAC, and KCl). The intended storage condition for the Alinity m STI AMP Kit is 2℃ to 8℃.
- . Alinity m STI CTRL Kit, List No. 09N17-085 consisting of negative controls and positive controls, each supplied as liquid in single-use tubes. The intended storage condition for the Alinity m STI Control Kit is -15°C to -25°C.
Nucleic acids from specimens are extracted automatically on-board the Alinity m System using the Alinity m Sample Prep Kit 1, Alinity m Lysis Solution, Alinity m Ethanol Solution, and Alinity m Diluent Solution. The Alinity m System employs magnetic microparticle technology to facilitate nucleic acid capture, wash and elution. The resulting purified nucleic acids are then combined with the liquid unit-dose activator reagent, lyophilized unit-dose Alinity m STI amplification reagents, and Alinity m Vapor Barrier Solution, and transferred by the instrument to an amplification/detection module for reverse transcription, PCR amplification, and real-time fluorescence detection.
Assay controls are tested at or above an established minimum frequency of every 24 hours to help ensure that instrument and reagent performance remain satisfactory. During each control event, a negative control and a positive control are processed through sample preparation and RT-PCR procedures that are identical to those used for specimens. Assay controls are used to demonstrate proper sample processing and assay validity. The controls do not indicate if bacterial cells have been adequately lysed.
The Alinity m STI amplification reagents include primers and a probe that amplify and detect the single copy human gene, ß-globin. Amplification and detection of the ß-globin gene demonstrates proper sample processing and adequate sample input. In addition, an exogenous internal control (containing an armored RNA sequence) is included in the lyophilized Alinity m STI amplification reagents to assess amplification efficiency and to confirm that no PCR inhibitors are present in the sample. The cellular control and internal control are both used to demonstrate assay validity.
The Alinity m STI Assay also utilizes the following accessories:
- . Alinity m STI Assay Application Specification File, List No. 09N17-03A
- . Alinity m System and System Software, List No. 08N53-002

2. Sample Size Used for the Test Set and Data Provenance
- Urogenital Specimens: A total of 7,099 male and female subjects were enrolled for the urogenital clinical study. Specimens were collected across 33 geographically diverse sites in the United States, including STI clinics, primary care offices, and gynecology practices. This was a prospective study. Data provenance is United States, from prospective collection.
- Number of results used in analysis for each analyte:
- CT: 12,903
- NG: 15,655
- TV: 18,843
- MG: 12,829
- Number of results used in analysis for each analyte:
- Extragenital Specimens: A total of 2,373 male and female subjects were enrolled. Specimens were previously collected and archived. Data provenance is United States, from archived specimens (retrospective).
- Number of results used in analysis for each analyte:
- CT (oropharyngeal): 2,316
- CT (rectal): 2,053
- NG (oropharyngeal): 2,312
- NG (rectal): 2,049
- Number of results used in analysis for each analyte:
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document does not explicitly state the "number of experts" or their "qualifications" involved in establishing the ground truth. Instead, the ground truth was established using comparator assays, which are commercially available nucleic acid amplification tests (NAATs) and, in some cases, culture. The results from these comparator assays were combined to derive a Patient Infected Status (PIS) or Composite Comparator (CC).
4. Adjudication Method for the Test Set
- Urogenital Specimens (PIS):
- CT or NG (Female): A minimum of 2 positive results (at least 1 from each comparator NAAT) for infection, or at least 1 comparator NAAT reported negative results for all sample types for not infected.
- TV or MG (Female): First 2 swab comparator NAAT results both positive, or 2 of 3 swab comparator NAAT results positive (if 3rd NAAT was a tie-breaker) for infection. First 2 swab comparator NAAT results both negative, or 2 of 3 swab comparator NAAT results negative (if 3rd NAAT was a tie-breaker) for not infected.
- CT, NG, TV, or MG (Male): A minimum of two comparator positive results for infection. If the comparator TV culture assay result was positive, the subject was categorized as infected for TV regardless of NAAT results. Two or more comparator NAAT results negative for not infected (for CT, NG, MG). For TV, negative culture AND one or more negative comparator NAATs for not infected.
- Extragenital Specimens (CC): A specimen was categorized as infected (for CT or NG) if a minimum of 2 comparator positive results were reported. It was categorized as not infected if a minimum of 2 comparator negative results was reported.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not done. The study compares the Alinity m STI Assay's performance against a composite ground truth derived from multiple established comparator assays, not directly evaluating human reader performance with and without AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, this was a standalone performance study. The Alinity m STI Assay is an automated PCR assay, and its results are directly compared to the established ground truth without involving human interpretation or modifications of its output in the primary performance analysis.
7. The Type of Ground Truth Used
The ground truth used was a Composite Comparator / Patient Infected Status (PIS/CC), derived from the combined results of multiple commercially available and clinically cleared comparator nucleic acid amplification tests (NAATs) and, for male TV, culture results.
8. The Sample Size for the Training Set
The document does not explicitly provide the sample size for the training set for the Alinity m STI Assay. The provided performance data (Sensitivity and Specificity tables) are from the validation (test) sets.
9. How the Ground Truth for the Training Set Was Established
Since the document does not provide information about a separate training set, it is assumed that the analytical studies and the design of the assay would have utilized reference materials and potentially early clinical samples for optimization and establishment of analytical performance characteristics (like LoD, inclusivity, cross-reactivity). However, specific details on how ground truth was established for a training set are not available in this document. The clinical studies described are for validation/testing, with ground truth established by comparator assays as detailed in point 4.

5.5 Intended Use
Alinity m STI AMP Kit:
The Alinity m STI Assay is an in vitro polymerase chain reaction (PCR) assay for use with the automated Alinity m System for the direct, qualitative detection and differentiation of ribosomal RNA from Chlamydia trachomatis (CT), DNA from Neisseria gonorrhoeae (NG), ribosomal RNA from Trichomonas vaginalis (TV), and ribosomal RNA from Mycoplasma genitalium (MG), to aid in the diagnosis of disease(s) caused by infection from these organisms. The assay may be used to test the following specimens from symptomatic and asymptomatic individuals for the following analytes:
CT: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, male urine, oropharyngeal swabs, and rectal swabs
NG: vaginal swabs (clinician-collected and self-collected in a clinical setting). endocervical swabs, gynecological specimens in ThinPrep PreservCyt Solution, male urine, oropharyngeal swabs, and rectal swabs
TV: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, gynecological specimens in ThinPrep PreservCyt Solution, female urine, and male urine
MG: vaginal swabs (clinician-collected and self-collected in a clinical setting), endocervical swabs, and male urine
A vaginal swab (self-collected or clinician-collected) is the preferred specimen type for MG testing in females due to higher clinical sensitivity compared to endocervical swabs. If endocervical swab specimens test negative, testing with a vaginal swab may be indicated if M. genitalium infection is suspected.
{10}------------------------------------------------
Alinity m multi-Collect Specimen Collection Kit:
The Alinity m multi-Collect Specimen Collection Kit is intended for the collection and transportation of male and female urine specimens, endocervical swab specimens, vaginal swab specimens, oropharyngeal swab specimens, and rectal swab specimens to stabilize nucleic acid for testing with the Alinity m STI Assay. Refer to the Alinity m STI Assay package insert for additional information.
The Alinity m multi-Collect Specimen Collection Kit is not intended for home use.
5.6 Similarities and Differences to Predicate Devices
The primary functional components of the Alinity m STI Assay are substantially equivalent to other legally marketed nucleic acid amplification tests (NAAT) intended for the qualitative detection of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), and Mycoplasma genitalium (MG).
The Alinity m STI Assay has the same general intended use as the predicate devices. Although there are some technological differences between the Alinity m STI Assay and the predicate devices, these differences do not raise new types of safety or effectiveness questions.

5.7 Performance Data
The following performance data were provided in support of the substantial equivalence determination.
Specific Performance Characteristics 5.7.1
5.7.1.1 Analytical Sensitivity
Urogenital Specimens
The limit of detection (LoD) for urogenital specimens was determined by testing dilutions of CT, NG, TV, and MG organisms in pooled negative vaginal swab matrix, pooled negative gynecological PreservCyt matrix, and pooled negative urine matrix. Two different strains were evaluated for each organism in each matrix: serovars D and E for CT (ATCC), strains Z437 and Z433 for NG (Zeptometrix), strains 30001 (ATCC) and MTZ (metronidazole-resistant, Zeptometrix) for TV, and strains SEA-1 and MEGA 216 (azithromycin-resistant) for MG (non-commercial source). For each strain and matrix, a minimum of 6 target levels were evaluated in at least 20 replicates using each of 2 lots. Probit analysis was performed to estimate the LoD for each strain and matrix for each lot. In cases where the probit model did not fit the data, the LoD was determined for each lot to be the target concentration with a detection rate 95% or greater.
The LoD claim for the Alinity m STI Assay is as follows for each of the organisms in urogenital specimen types:
- CT: 17.0 Elementary Bodies (EB)/mL .
- NG: 7.5 Colony Forming Units (CFU)/mL .
- . TV: 0.1 TV/mL
- . MG: 165 Genome Equivalents (GE)/mL
Extragenital Specimens
The LoD for extragenital specimens was determined by testing dilutions of CT and NG organisms in pooled negative oropharyngeal swab matrix and pooled negative rectal
{16}------------------------------------------------
swab matrix. Two different strains were evaluated for each organism in each matrix: serovars D and E for CT (ATCC) and strains Z437 and Z433 (Zeptometrix) for NG. For each strain and matrix, a minimum of 3 target levels were evaluated in 20 replicates using one reagent lot. The LoD level was determined to be the concentration with a detection rate of 95% or greater where the target level 2-fold below was less than 95%.
The LoD claim for the Alinity m STI Assay is as follows for each of the organisms in extragenital specimen types:
- . CT: 17.0 EB/mL
- . NG: 7.5 CFU/mL

5.7.1.4 Evaluation of Potential Interfering Substances
Urogenital Specimens
The potential for interference in the Alinity m STI Assay was assessed with 35 substances that may be found in urine, vaginal swab, endocervical swab, and/or PreservCyt samples (Table 4). Substances were diluted into pooled vaginal swab, pooled gynecological PreservCyt, and/or pooled urine matrices. For each substance and matrix, both CT, NG, TV, and MG positive and negative samples were tested. The positive matrices contained CT, NG, TV, and MG organisms at 3 times the claimed assay LoD. Two different strains of each organism were used in this study (CT serovars D and E, NG strains Z433 and Z437, TV strains 30001 and MTZ, and MG strains SEA-1 and MEGA 216). No interference was observed in the presence of any of the substances at the concentrations shown in Table 4 for all positive and negative samples. Assay interference was observed in the presence of seminal fluid at concentrations greater than 3.0% in PreservCyt samples. Cycle number delays were observed for seminal fluid. yglobulin, and glucose in urine and seminal fluid. mucus, and Preparation H Hemorrhoidal Cream in PreservCyt, which could result in interference at lower target levels.

5.7.1.7 Carryover
The carryover rate for Alinity m STI Assay was determined by testing alternating replicates of STI high positive samples and STI negative samples across multiple runs. The high positive samples were prepared with titers greater than or equal to 3.0x105 EB/mL for CT, 1.6x104 CFU/mL for NG, 2.3x104 TV/mL for TV, and 1.1x106 GE/mL for MG. Of the 548 negative samples tested, 1 sample was reported positive for TV and 1 sample was reported as positive for both CT and TV. All negative samples were reported negative for NG and MG. The overall carryover rate for CT was 0.2% (1/548, 95% CI: 0.0% to 1.0%), the overall carryover rate for TV was 0.4% (2/548, 95% CI: 0.1% to 1.3% ), and the overall carryover rate for NG and MG was 0.0% (0/548, 95% CI: 0.0% to 0.7%). The overall sample carryover rate was 0.4% (2/548, 95% CI: 0.1% to 1.3%).
Reproducibility Study 5.7.1.8
Reproducibility performance of the Alinity m STI Assay was evaluated by testing panel members in 3 different sample matrices: urine matrix, swab matrix, and PreservCyt matrix. For each applicable specimen matrix, a 13-member panel was prepared with combinations of CT, NG, TV, and MG at sub-LoD (High Negative), claimed LoD, low positive (2x claimed LoD), high positive, and negative target levels. A total of 3 Alinity m STI AMP Kit lots were used. Each of the 3 clinical sites tested 2 Alinity m STI AMP Kit lots, on 5 non-consecutive days for each lot. A total of 5 replicates of each panel member were tested on each of 5 days. Each of the 3 clinical sites used different lots of Alinity m STI CTRL Kits and Alinity m Sample Prep Kit 1. The reproducibility results for CT, NG, TV, and MG are summarized in Table 12, Table 13, and Table 14, respectively.

5.7.2 Clinical Performance
Clinical Study Results - Urogenital Specimens 5.7.2.1
Performance characteristics of the Alinity m STI Assay with urogenital specimens were established in a multicenter clinical study conducted in the United States. Specimens were collected from subjects 14 years of age or older at 33 geographically diverse sites that included but were not limited to STI clinics, primary care offices, and gynecology practices. A total of 7,099 male and female, asymptomatic and symptomatic subjects were enrolled. Study subjects were classified as symptomatic if the subject reported STI related symptoms.
Each female subject provided up to 8 specimens, including 1 urine specimen, 1 selfcollected vaginal swab, 3 clinician-collected vaginal swabs, 2 endocervical swabs, and 1 ThinPrep (PreservCyt) cytology specimen. Each male provided 1 urine specimen.
Specimen testing methods included the Alinity m STI Assay and comparator assays for CT, NG, TV, and MG. Alinity m STI testing was performed at 3 external clinical testing sites. Comparator assays for CT and NG included 2 commercially available nucleic acid amplification tests (NAAT) for females (each NAAT tested with 1 swab and 1 urine specimen) and 3 commercially available NAATs for males (each NAAT tested with urine). Comparator assays for TV included 3 NAATs tested with swab specimens and 2 NAATs tested with urine specimens for females and 2 NAATs and culture tested with urine for males. Comparator assays for MG included 3 NAATs for females (each tested with a vaginal swab) and males (each tested with urine).
For each subject, a patient infected status (PIS) was determined based on the combined results from the comparator assays. A female subject was categorized as infected for CT or NG if a minimum of 2 positive results (at least 1 from each comparator NAAT) was reported. For CT, female subjects with positive results on both comparator urine specimens and negative results on both comparator swab specimens (endocervical swab from NAAT 1 and clinician-collected vaginal swab specimens from NAAT 2) were categorized as infected for urine and not infected for swab specimens (there were 2 female subjects that were negative for CT in the swab samples and positive in urine by
{38}------------------------------------------------
both comparator NAATs). A female subject was categorized as not infected for CT or NG if at least 1 of the comparator NAATs reported negative results for all sample types. Refer to Table 20, Table 21, Table 24 and Table 25 for the female PIS algorithm. A female subject was categorized as infected for TV or MG if the first 2 swab comparator NAAT results were both positive or if 2 of the 3 swab comparator NAAT results were positive in cases where the 3ª NAAT was used as a tie-breaker. A female subject was categorized as not infected for TV or MG if the first 2 swab comparator NAAT results were both negative or if 2 of the 2 swab comparator NAAT results were negative in cases where 3rd NAAT was used as a tie-breaker. Refer to Table 28, Table 32 and Table 33 for the female PIS algorithm.
A male subject was categorized as infected for CT, NG, TV, or MG if a minimum of two comparator positive results was reported. If the comparator TV culture assay result was positive, the subject was categorized as infected for TV regardless of NAAT results. A male subject was categorized as not infected for CT, NG, or MG if two or more comparator NAAT results were negative. For TV, a male subject was categorized as not infected if the TV culture assay result was negative, and if one or more comparator NAATs were negative. Refer to Table 22, Table 26, Table 26, Table 27, Table 30, Table 31, Table 34 and Table 35 for the male PIS algorithm.
If a PIS could not be determined due to missing and/or indeterminate results from the comparator assays, the subject was excluded from the analysis for that analyte. Out of 7099 subjects, PIS could not be determined for 1 or more analytes for 171 subjects (42 subjects for CT, 32 subjects for NG, 73 subjects for TV, 93 subjects for MG).
Alinity m STI test results were compared to the PIS for calculation of assay sensitivity and specificity. A total of 12,903 CT, 15,655 NG, 18,843 TV, and 12,829 MG results were used in the analysis. The results were analyzed by gender, specimen type, and the presence of symptoms. CT sensitivity and specificity for female and male subjects by specimen type and by symptom status are presented in Table 15. NG sensitivity and specificity for female and male subjects by specimen type and by symptom status are presented in Table 16. TV sensitivity and specificity for female and male subjects by
{39}------------------------------------------------
specimen type and by symptom status are presented in Table 17. MG sensitivity and specificity for female and male subjects by specimen type and by symptom status are presented in Table 19.
For the urogenital study, approximately 4.7% of sample results were invalid on the initial test. Specimens with initial invalid results were retested. Out of a total of 20,145 specimens, the number of specimens with final invalid results for CT, NG, TV and MG were 37, 49, 54 and 38, respectively, or approximately 0.3%.

Table 17. TV Clinical Sensitivity and Specificity by Gender, Specimen Type and Symptom Status for Urogenital Specimens
For female urine, the TV result of the Alinity m STI Assay was compared against a specimen-specific agreement.. A female urine specimen was considered positive for TV if at least 1 comparator NAAT was positive for the urine specimen. A female urine specimen was considered negative if both comparator NAATs were negative for the urine specimen. If a TV specimen-specific status for female urine could not be determined due to missing and/or indeterminate results from the urine comparator assays, the subject was excluded from the analysis for that analyte. The specimen-specific TV status could not be determined for 37 subjects. TV specimen-specific positive and negative agreement for female urine by symptom status are presented in Table 18. The TV clinical sensitivity based on the PIS was up to 6.6% lower in female urine than in vaginal swab specimens.

Clinical Study Results - Extragenital Specimens 5.7.2.2
Performance characteristics of the Alinity m STI Assay with extragenital specimens were established in a multicenter clinical study conducted in the United States. Archived specimens were previously collected with an IRB/IEC approved consent. A total of 2,373 male and female, asymptomatic and symptomatic subjects were enrolled. Three oropharyngeal and 3 rectal specimens were collected from each subject using a common collection device created specifically for the study.
Specimen testing methods included the Alinity m STI Assay and 3 commercially available CT/NG NAAT comparator assays for each oropharyngeal and rectal specimen.
Comparator NAAT results were used to establish an anatomic site-specific composite comparator (CC). A specimen was categorized as infected for CT or NG if a minimum of 2 comparator positive results were reported and as not infected for CT or NG if a minimum of 2 comparator negative results was reported. Refer to Table 46 through Table 49 for the CC algorithm. If the specimen CC could not be determined for a given analyte (CT or NG) due to missing and/or indeterminate results from the comparator assays, the specimen was excluded from the analysis for that analyte. CC could not be determined for 6 oropharyngeal and 8 rectal specimens for CT, and 10 oropharyngeal and 6 rectal specimens for NG.
Alinity m STI CT and NG test results were compared to the CC for calculation of assay sensitivity and specificity. A total of 2,316 CT and 2,312 NG results from oropharyngeal specimens, and a total of 2,053 CT and 2,049 NG results from rectal specimens were used in the analysis. The results were analyzed by specimen type and the presence of symptoms. Sensitivity and specificity for CT for oropharyngeal and rectal specimens are presented in Table 44. Sensitivity and specificity for NG for oropharyngeal and rectal specimens are presented in Table 45.

5.8 Conclusions Drawn from the Studies
The analytical and clinical study results demonstrate that the Alinity m STI Assay on the Alinity m System performs comparably to the predicate devices in detecting Chlamydia trachomatis, Neisseria gonorrhea, Trichomonas vaginalis, and Mycoplasma genitalium microorganisms that cause sexually transmitted infections and support a substantial equivalence decision.
§ 866.3393 Device to detect nucleic acids from non-viral microorganism(s) causing sexually transmitted infections and associated resistance marker(s).
(a)
Identification. A device to detect nucleic acids from non-viral microorganism(s) causing sexually transmitted infections and associated resistance marker(s) is an in vitro diagnostic device intended for the detection and identification of nucleic acids from non-viral microorganism(s) and their associated resistance markers in clinical specimens collected from patients suspected of sexually transmitted infections. The device is intended to aid in the diagnosis of non-viral sexually transmitted infections in conjunction with other clinical and laboratory data. These devices do not provide confirmation of antibiotic susceptibility since mechanisms of resistance may exist that are not detected by the device.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The intended use for the labeling required under § 809.10 of this chapter must include a detailed description of targets the device detects, the results provided to the user, the clinical indications appropriate for test use, and the specific population(s) for which the device is intended.
(2) Any sample collection device used must be FDA-cleared, -approved, or -classified as 510(k) exempt (standalone or as part of a test system) for the collection of specimen types claimed by this device; alternatively, the sample collection device must be cleared in a premarket submission as a part of this device.
(3) The labeling required under § 809.10(b) of this chapter must include:
(i) A detailed device description, including reagents, instruments, ancillary materials, all control elements, and a detailed explanation of the methodology, including all pre-analytical methods for processing of specimens;
(ii) Detailed discussion of the performance characteristics of the device for all claimed specimen types based on analytical studies, including Limit of Detection, inclusivity, cross-reactivity, interfering substances, competitive inhibition, carryover/cross contamination, specimen stability, within lab precision, and reproducibility, as appropriate;
(iii) Detailed descriptions of the test procedure, the interpretation of test results for clinical specimens, and acceptance criteria for any quality control testing;
(iv) Limiting statements indicating that:
(A) A negative test result does not preclude the possibility of infection;
(B) The test results should be interpreted in conjunction with other clinical and laboratory data available to the clinician;
(C) Reliable results are dependent on adequate specimen collection, transport, storage, and processing. Failure to observe proper procedures in any one of these steps can lead to incorrect results; and
(D) If appropriate (
e.g., recommended by the Centers for Disease Control and Prevention, by current well-accepted clinical guidelines, or by published peer reviewed research), that the clinical performance is inferior in a specific clinical subpopulation or for a specific claimed specimen type; and(v) If the device is intended to detect antimicrobial resistance markers, limiting statements, as appropriate, indicating that:
(A) Negative results for claimed resistance markers do not indicate susceptibility of detected microorganisms, as resistance markers not measured by the assay or other potential mechanisms of antibiotic resistance may be present;
(B) Detection of resistance markers cannot be definitively linked to specific microorganisms and the source of a detected resistance marker may be an organism not detected by the assay, including colonizing flora;
(C) Detection of antibiotic resistance markers may not correlate with phenotypic gene expression; and
(D) Therapeutic failure or success cannot be determined based on the assay results, since nucleic acid may persist following appropriate antimicrobial therapy.
(4) Design verification and validation must include:
(i) Detailed device description documentation, including methodology from obtaining sample to result, design of primer/probe sequences, rationale for target sequence selection, and computational path from collected raw data to reported result (
e.g., how collected raw signals are converted into a reported result).(ii) Detailed documentation of analytical studies, including, Limit of Detection, inclusivity, cross-reactivity, microbial interference, interfering substances, competitive inhibition, carryover/cross contamination, specimen stability, within lab precision, and reproducibility, as appropriate.
(iii) Detailed documentation and performance results from a clinical study that includes prospective (sequential) samples for each claimed specimen type and, when determined to be appropriate by FDA, additional characterized clinical samples. The study must be performed on a study population consistent with the intended use population and compare the device performance to results obtained from FDA accepted comparator methods. Documentation from the clinical studies must include the clinical study protocol (including a predefined statistical analysis plan) study report, testing results, and results of all statistical analyses.
(iv) A detailed description of the impact of any software, including software applications and hardware-based devices that incorporate software, on the device's functions.
