The description details a PCR-based diagnostic system with automated interpretation of melt curve analysis data. There is no mention of AI or ML algorithms being used for data processing or interpretation. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
No
The device is an in vitro diagnostic (IVD) test that detects and identifies viral nucleic acids for diagnosis, not for treating or preventing disease.
Yes.
The device is intended for the simultaneous, qualitative detection and identification of multiple respiratory viral nucleic acids and "aids in diagnosis if used in conjunction with other clinical and epidemiological information findings."
No
The device description clearly outlines hardware components like the BIOFIRE® SPOTFIRE® System, which includes coordinated systems of inflatable bladders, seal points, pneumatic pistons, and Peltier elements. While software is crucial for operation and interpretation, it is integral to a larger hardware system that performs the PCR and analysis.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's a "multiplexed polymerase chain reaction (PCR) test intended for use with the BIOFIRE® SPOTFIRE® System for the simultaneous, qualitative detection and identification of multiple respiratory viral nucleic acids in nasopharyngeal swab (NPS) specimens obtained from individuals with signs and symptoms of respiratory tract infection, including COVID-19." This clearly describes a test performed in vitro (outside the body) on a biological specimen (nasopharyngeal swab) to provide diagnostic information.
- Device Description: The description details a system that processes a biological sample (NPS specimen) using chemical reagents and a PCR-based method to detect specific viral nucleic acids. This is the core function of an in vitro diagnostic device.
- Compatibility with an IVD System: It is stated that the device is "compatible with the BIOFIRE® System, a polymerase chain reaction (PCR)-based in vitro diagnostic system for infectious disease testing." This further confirms its role within an IVD framework.
- Regulatory Classification: The "Intended User / Care Setting" section indicates "Prescription Use (Part 21 CFR 801 Subpart D)" and "Low (CLIA-waived)". These are regulatory classifications typically associated with medical devices, and specifically, in vitro diagnostic devices.
- Performance Studies: The mention of performance data and comparison to a predicate device (K213954 – BIOFIRE® SPOTFIRE® Respiratory (R) Panel) which is also likely an IVD, is consistent with the regulatory requirements for IVDs.
In summary, the device meets the definition of an in vitro diagnostic device as it is intended for use outside the body to examine specimens from the human body to provide information for the diagnosis of disease or other conditions.
N/A
Intended Use / Indications for Use
The BIOFIRE® SPOTFIRE® Respiratory (R) Panel Mini) is a multiplexed polymerase chain reaction (PCR) test intended for use with the BIOFIRE® SPOTFIRE® System for the simultaneous, qualitative detection and identification of multiple respiratory viral nucleic acids in nasopharyngeal swab (NPS) specimens obtained from individuals with signs and symptoms of respiratory tract infection, including COVID-19.
The following organism types and subtypes are identified and differentiated using the SPOTFIRE R Panel Mini:
- Coronavirus SARS-CoV-2
- · Human rhinovirus
- · Influenza A virus
- · Influenza B virus
- · Respiratory syncytial virus
Nucleic acids from the viral organisms identified by this test are generally detectable in NPS specimens during the acute phase of infection. The detection of specific viral nucleic acids from individuals exhibiting signs and/or symptoms of respiratory infection are indicative of the identified microorganism and aids in diagnosis if used in conjunction with other clinical and epidemiological information findings. The results of this test should not be used as the sole basis 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, or lower respiratory tract infection that may not be detected by an NPS specimen. Positive results do not rule out coinfection with other organisms. The agent(s) detected by the SPOTFIRE R Panel Mini 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 respiratory tract infection.

Device Description
The BIOFIRE SPOTFIRE Respiratory (R) Panel Mini simultaneously identifies five different respiratory viral pathogens in nasopharyngeal swabs (NPS) from individuals with signs and symptoms of respiratory tract infection (see Table 1). The SPOTFIRE R Panel Mini is compatible with the BIOFIRE® System, a polymerase chain reaction (PCR)-based in vitro diagnostic system for infectious disease testing. The BIOFIRE System Software executes the SPOTFIRE R Panel Mini test and interprets and reports the test results.
A test is initiated by loading Hydration into one port of the SPOTFIRE R Panel Mini pouch and NPS specimen mixed with the provided Sample Buffer into the other port of the SPOTFIRE R Panel Mini pouch and placing it in the SPOTFIRE System. The pouch contains all of the reagents required for speciment 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 SPOTFIRE System Software quides the user through the pouch into the instrument, scanning the pouch barcode, entering the sample identification, and initiating the run.
The SPOTFIRE System contains coordinated systems 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 liguid 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 multiple plungers in order to deliver the rehydrated reagents into the blisters at the appropriate times. Two Peltier and cooling of the pouch to drive the PCR reactions and the melt curve analysis.
Nucleic acid extraction occurs within the SPOTFIRE R Panel Mini pouch using mechanical lysis followed by purification using standard magnetic bead technology. After extracting and purifying nucleic acids from the unprocessed sample, the SPOTFIRE System performs a nested multiplex PCR that is executed in two stage, the SPOTFIRE System 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 doublestranded 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 SPOTFIRE System 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.

The SPOTFIRE System 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 SPOTFIRE R Panel Mini is substantially equivalent to the SPOTFIRE R Panel (K213954), which was cleared on February 03, 2023, and determined to be a Class II device under the classification code 21 CFR 866.3981.
A table comparing the SPOTFIRE R Panel Mini to the SPOTFIRE R Panel is provided in Table 2.

Summary of Performance Data:
The performance data for the SPOTFIRE R Panel Mini is identical to the SPOTFIRE R Panel (K213954), but only contains data for the five analytes detected by the SPOTFIRE R Panel Mini (Coronavirus SARS-CoV-2, human rhinovirus, influenza A virus, influenza B virus, and respiratory syncytial virus). Please see the BIOFIRE Respiratory Panel Mini Instructions for Use for performance tables.
Conclusion:
The fundamental scientific technology, performance, and risk of the SPOTFIRE R Panel Mini is unchanged from the legally marketed SPOTFIRE R Panel. There is no change to the product itself, except for modified software that has been verified and validated to show no change in safety and effectiveness. Therefore, the SPOTFIRE R Panel Mini performs as well as the predicate device.
