The description focuses on a real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) test kit and instrument for qualitative detection of viral RNA. There is no mention of AI or ML in the intended use, device description, or performance studies. The analysis is based on standard molecular diagnostic techniques.
No
The device is an in vitro diagnostic (IVD) test kit used to detect viral RNA for diagnostic purposes, not to treat or provide therapy to a patient.
Yes
The device qualitatively detects Influenza A/H5 viral RNA in patient specimens to presumptively identify the virus, which is a diagnostic function.
No
The device is a test kit containing reagents (freeze-dried assays with primer and fluorescent-probe sets) used in conjunction with a separate instrument and software. It is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the kit is intended for "in vitro qualitative detection of Influenza A/H5 (Asian lineage) viral RNA in patient nasopharyngeal swab (NPS) or throat swab (TS) specimens". "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Device Description: The "Device Description" also reinforces this by describing the kit as a "real-time reverse transcriptase polymerase chain reaction (rRT-PCR) test kit, which... allows the qualitative in vitro detection of Influenza A/H5 (Asian lineage) viral RNA."
- Specimen Type: The device analyzes patient specimens (nasopharyngeal swab and throat swab), which is typical for IVDs used for diagnostic purposes.
- Diagnostic Purpose: The intended use is for the "presumptive laboratory identification of Influenza A/H5 (Asian lineage) virus" and for "Providing epidemiological information" and "Identifying patients who may be infected". These are all diagnostic or public health surveillance activities performed outside the body.
Therefore, based on the provided information, the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit clearly fits the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is intended for use in real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) assays on the Joint Biological Agent Identification and Diagnostic System (JBAIDS) instruments for the in vitro qualitative detection of Influenza A/H5 (Asian lineage) viral RNA in patient nasopharyngeal swab (NPS) or throat swab (TS) specimens for the presumptive laboratory identification of Influenza A/H5 (Asian lineage) virus.
Testing with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit should be in conjunction with other laboratory testing and clinical observations for the following indications:
-
- Providing epidemiological information for the surveillance of human infection with Influenza A/H5 (Asian lineage) virus.
-
- Identifying patients who may be infected with Influenza A/H5 (Asian lineage) virus based on clinical and epidemiological risk factors.
Testing with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit should not be performed unless the patient meets the most current U.S. Department of Health and Human Services (DHHS) clinical and epidemiologic criteria for testing suspected A/H5 specimens.
The definitive identification of influenza A/H5 (Asian lineage) either directly from patient specimens or from virus cultures requires additional laboratory testing, along with clinical and epidemiological assessment in consultation with national influenza surveillance experts.
Negative results do not preclude influenza virus infection and should not be used as the sole basis for treatment or other patient management decisions.
Use is limited to laboratories with appropriate biosafety equipment and containment procedures. It is intended for use by experienced laboratory personnel who have training in standardized molecular testing procedures and expertise in viral diagnosis, and have received training on the JBAIDS Instrument.
If infection with a novel influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions for novel virulent influenza viruses and sent to state or local health departments for testing. Viral culture should not be attempted in these cases unless a biosafety laboratory (BSL) 3+ facility is available to receive and culture specimens.

Device Description
The Joint Biological Agent Identification and Diagnostic System (JBAIDS) Influenza A/H5 (Asian lineage) Detection Kit is a real-time reverse transcriptase polymerase chain reaction (rRT-PCR) test kit, which, when used with the JBAIDS instrument and software, allows the qualitative in vitro detection of Influenza A/H5 (Asian lineage) viral RNA. The kit contains two freeze-dried assays with primer and fluorescent-probe sets for the detection of Influenza A/H5 (Asian lineage) viral RNA. In particular, the two assays specifically target distinct regions of the influenza A hemagglutinin gene of the highly pathogenic H5N1 viruses from the Asian lineage, without detection of other influenza A virus subtypes, including the North American lineage influenza A/H5 viruses. The tests are performed using the previously FDA-cleared JBAIDS instrument and software. A human gene target assay will be used as an inhibition and extraction control.
Assay Principle: Before testing, specimens are purified using Idaho Technology's 1-2-3TM Sample Purification Kits. The resulting purified sample is added to Unknown reagent vials and a Sample Control reagent vial, along with reconstitution buffer. When the viral RNA is present, a fragment of Influenza A/H5 RNA is transcribed and amplified. The amplicon is detected by fluorescence using a specific hydrolysis probe. Each probe is labeled on one end with a fluorescent reporter moiety (6-carboxyfluorescein (6-FAM)) and elsewhere with a quencher moiety (carboxy tetramethylrhodamine (TAMRA)). When the probe is intact, the quencher absorbs the light emitted by the reporter moiety. During PCR. the probe hybridizes to the target sequence before the exonuclease activity of Taq polymerase hydrolyzes the probe, separating the fluorophore from the quencher and permitting detection of the fluorescent signal generated by the reporter. The fluorescent signal increases as additional templates are amplified and more probes are hydrolyzed.
JBAIDS Software analyzes the fluorescence amplification curves and reports results as positive, negative, or uncertain. A failure of the Positive or Negative Control will result in the entire run being called invalid. Failure of the Sample Control yields a result of "sample control failure" when the associated sample has a negative result for the target assay. Retesting is required to resolve uncertain, invalid or sample control failure results.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
-
- Analytical Specificity Limit of Detection: The limit of detection (LoD) for the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit was determined using TS and NPS specimens spiked with two different live virus strains (see Table 3). The LoD was first estimated by testing NPS and TS specimens soiked with 10-fold dilutions of virus. The specimens were purified with the IT 1-2-3 TM VIBE Sample Purification Kit and the IT 1-2-3 110 Platinum Path Purification Kit and tested. Once estimated. the LoD was confirmed by testing 20 individual specimens (from independent donors) spiked at the estimated LoD of 50 EID50/mL. This level of virus was successfully detected for all 20 NPS and TS specimens purified with either the IT 1-2-31M VIBE or the IT 1-2-3TM Platinum Path Kit Purification Kits.
-
- Analytical Specificity Inclusivity & Reactivity: Eight Influenza A/H5 (Asian lineage) strains were spiked into TS specimens at multiple concentrations and tested using the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit. The lowest level of virus that was detected is shown in Table 4. For all eight strains, a spike level of 500-1000 TCID50/mL was determined to have similar performance (with regard to detection and Cp values) as specimens spiked with 50 EID50/mL of the egg grown viruses used in the LoD study.
-
- Analytical Specificity Exclusivity: To ensure that the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit does not cross react with other organisms, TS specimens spiked with high concentrations of the non-target organisms listed in Table 5 were prepared and tested. Specimens spiked with all 45 (100%) organisms were negative with both the Target 1 and Target 2 assays.
-
- Clinical Performance: Due to the rarity of infection with the influenza A/H5 (Asian lineage) virus, it was not possible to evaluate the clinical sensitivity of the test system using true clinical samples. As a result, a surrogate clinical sensitivity assessment was performed and a clinical specificity assessment was conducted using influenza-negative clinical specimens spiked with influenza A/H5 (Asian lineage) virus.
-
- Surrogate Clinical Sensitivity: A panel of surrogate samples consisting of eight strains of Influenza A/H5 (Asian lineage) and six strains of seasonal influenza (Table 6) were spiked into TS or NPS specimens collected in viral transport medium (VTM). The complete panel, for both TS and NPS specimens, consisted of the following: Influenza A/H5 viruses at limit of detection (LoD), 5x LoD, 10x LoD, and 100x LoD (LoD was estimated to be 500 TCIDso/mL); seasonal influenza viruses at LoD and 100x LoD; and six specimens that were not spiked with any virus. Each specimen was purified with the IT 1-2-3 M VIBE and IT 1-2-3 TM Platinum Path Sample Purification Kits. As expected, all seasonal influenza (48 total results) and influenza-negative specimens (24 total results) produced negative results. Of the 128 Influenza A/H5 virus-containing specimens. 126 produced positive results (98% success).
-
- Clinical Specificity: A multicenter clinical study was conducted over a 4-month period using frozen, banked NPS and TS specimens that had been previously tested for respiratory pathogens. The specimens were obtained and tested at 3 different test sites.
Three hundred fourteen (314) NPS specimens purified using the IT 1-2-3"M VIBE Sample Purification Kit and 299 NPS specimens purified using the IT 1-2-3TM Platinum Path Purification kit had valid negative results for both the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit and the CDC rRT Flu Panel. Similarly, 298 VIBE purified and 283 Platinum Path purified TS specimens had valid negative results with both kits. These results demonstrate that the clinical specificity for NPS and TS specimens purified with the IT 1-2-3 100 VIBE or Platinum Path Purification Kits and tested with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is at least 99% with 95% confidence.
- Clinical Specificity: A multicenter clinical study was conducted over a 4-month period using frozen, banked NPS and TS specimens that had been previously tested for respiratory pathogens. The specimens were obtained and tested at 3 different test sites.

Special conditions for use statement(s)
- . For prescription use only
- Although this test has been shown to detect cultured human-derived Influenza A subtype . H5N1 virus (Asian lineage), the performance characteristics of this test with specimens from humans infected with influenza H5N1 (Asian lineage) or other avian influenza viruses are unknown.
- Clinical specificity was established when influenza A/H3 and A/H1 were the . predominant influenza A viruses in circulation. When other influenza A viruses are emerging, clinical specificity may vary.
- Optimum specimen types and timing for peak viral levels during infections caused by a . novel influenza A virus have not been determined. Collection of multiple specimens from the same patient may be necessary to detect the virus.
- . This product can be used only with the JBAIDS instrument.
- . Results from this test are intended for use with other laboratory tests and in consultation with national influenza experts.
- A negative result does not exclude the possibility of Influenza A/H5 (Asian lineage) . infection. Negative test results may occur from improper specimen collection, presence of inhibitors, technical error, or sample mix-up. Test results may be affected by concurrent antiviral therapy or levels of organism in the specimen that are below the limit of detection for the test.
- The performance of the assay has not been established in individuals who received an . H5N1 vaccine.
- . This test has not been validated for testing specimens other than those specified or for samples that have been purified using other than the recommended IT 1-2-3TM Sample Purification Kits.
- As for any PCR assay, improper technique can lead to cross-contamination and false . positive results. Good laboratory technique is essential to the proper performance of this assay. The JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is intended for use by laboratory personnel who have received training on the JBAIDS instrument to perform and interpret the results from this procedure.
- The JBAIDS Influenza A/H5 (Asian lineage) Detection Kit may not generate . reproducibly positive results when testing samples that have influenza A/H5 (Asian
4
lineage) viral RNA concentrations lower than the LoD concentration, but higher than the assay cutoff concentration.
Substantial Equivalence: The JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is substantially equivalent to the Centers for Disease Control and Prevention (CDC) Human Influenza Virus Real-time RT-PCR Detection and Characterization Panel (rRT-PCR Flu Panel) (K080570).
The CDC rRT-PCR Flu Panel is a panel of oligonucleotide primers and dual-labeled hydrolysis forobes for the qualitative detection and differentiation of influenza viruses. The panel can be used to test nasopharyngeal specimens, respiratory specimens or virus culture.
Prior to testing, the samples are purified with one of four commercial available sample purification methods (see chart below). A master mix is prepared by combining the appropriate quantities of primers and probes from the rRT-PCR Flu Panel with a commercially available reverse transcription master mix. The master mix is aliquoted into a 96 well plate followed by addition of the purified samples and controls. The prepared place on an ABI 7500 Fast Dx Real-Time PCR instrument and thermocycled according to the cycling conditions described in the rRT-PCR Flu Panel product insert.
Each run on the ABI includes a no-template control (nuclease-free water), a H5 virus control (noninfectious reassortant influenza A/H5 virus containing cultured human cells) and a human specimen control (cultured human cells). The human specimen control is extracted with the test samples and is intended to ensure that the extraction process was properly performed. The notemplate and H5 virus control templates are added to the PCR plate prior to thermocycling.
At the conclusion of the run, the operator is required to set a baseline for all assays included in the run. The operator is then required to interpret the test results for each sample based on the results of the controls and the Ct values for each sample.

- Clinical Specificity: A multicenter clinical study was conducted over a 4-month period using frozen, banked NPS and TS specimens that had been previously tested for respiratory pathogens. The specimens were obtained and tested at 3 different test sites.
Three hundred fourteen (314) NPS specimens purified using the IT 1-2-3"M VIBE Sample Purification Kit and 299 NPS specimens purified using the IT 1-2-3TM Platinum Path Purification kit had valid negative results for both the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit and the CDC rRT Flu Panel. Similarly, 298 VIBE purified and 283 Platinum Path purified TS specimens had valid negative results with both kits. These results demonstrate that the clinical specificity for NPS and TS specimens purified with the IT 1-2-3 100 VIBE or Platinum Path Purification Kits and tested with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is at least 99% with 95% confidence. Results are summarized in Table 7.

Indications for Use
510(k) Number: K100287
Device Name: JBAiDS Influenza A/H5 (Asian lineage) Detection Kit
Indications for Use:
The JBAIDS Influenza A/H5 (Asian lineage) Detection Kit is intended for use in real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) assays on the Joint Biological Agent Identification and Diagnostic System (JBAIDS) instruments for the in vitro qualitative detection of Influenza A/H5 (Asian Iineage) viral RNA in patient nasopharyngeal swab (NPS) or throat swab (TS) specimens for the presumptive laboratory identification of Influenza A/H5 (Asian lineage) virus.
Testing with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit should be in conjunction with other laboratory testing and clinical observations for the following indications:
-
- Providing epidemiological information for the surveillance of human infection with Influenza A/H5 (Asian lineage) virus.
-
- Identifying patients who may be infected with Influenza A/H5 (Asian lineage) virus based on clinical and epidemiological risk factors.
Testing with the JBAIDS Influenza A/H5 (Asian lineage) Detection Kit should not be performed unless the patient meets the most current U.S. Department of Health and Human Services (DHHS) clinical and epidemiologic criteria for testing suspected A/H5 specimens.
The definitive identification of influenza A/H5 (Asian lineage) either directly from patient specimens or from virus cultures requires additional laboratory testing, along with clinical and epidemiological assessment in consultation with national influenza surveillance experts.
Negative results do not preclude influenza virus infection and should not be used as the sole basis for treatment or other patient management decisions.
Use is limited to laboratories with appropriate biosafety equipment and containment procedures. It is intended for use by experienced laboratory personnel who have training in standardized molecular testing procedures and expertise in viral diagnosis, and have received training on the JBAIDS Instrument.
If infection with a novel influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions for novel virulent influenza viruses
12
and sent to state or local health departments for testing. Viral culture should not be attempted in these cases unless a biosafety laboratory (BSL) 3+ facility is available to receive and culture specimens.
