The Joint Biological Agent Identification and Diagnostic System (JBAIDS) Influenza A & B Detection Kit is intended for use on the JBAIDS instruments, for the in vitro qualitative detection of Influenza A and Influenza B viral nucleic acids isolated and purified from nasopharyngeal swab (NPS) and nasopharyngeal wash (NPW) specimens from human patients with signs and symptoms of respiratory infection. The JBAIDS Influenza A & B Detection Kit contains reverse transcriptase real-time polymerase chain reaction (rRT-PCR) assays that target the Matrix protein gene of Influenza A viruses, and the Non-structural protein gene of Influenza B viruses. This kit is not intended to detect Influenza C viruses. Test results are to be used in conjunction with other clinical and epidemiological information. Negative results do not preclude influenza virus infection and should not be used as the sole basis for treatment or other patient management decisions. Performance characteristics for detection of influenza A were established when 2009 H1N1 Influenza, Influenza A H1N1, and Influenza A H3N2 were the predominant influenza A viruses in circulation. Due to low seasonal prevalence, performance characteristics for detection of seasonal Influenza A/H1 were established primarily with retrospective and surrogate clinical specimens. When other influenza A viruses are present, performance characteristics may vary. All users, analysts, and any person reporting diagnostic results from use of this device should be trained to perform and interpret the results from this procedure by JBAIDS instructors or designees prior to use. Use of this device is limited to designated Department of Defense (DoD) laboratories equipped with the JBAIDS instruments. 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.

The JBAIDS Influenza A & B Detection Kit is a rRT-PCR test kit, which, when used with the JBAIDS instrument and software, allows the qualitative in vitro detection of influenza A and B viral RNA. These two assays have been optimized as freeze-dried assays with primer and fluorescent-probe sets for the detection of influenza A and B viral RNA. In particular, the influenza A assay targets a region of the matrix gene specific to the influenza A virus genera, and the influenza B assay targets a region of the non-structural gene specific to the influenza B virus genera. The tests are performed using the previously FDA-cleared JBAIDS instrument and software. A human gene target assay (RNAseP target) will be used as an inhibition and extraction control.
