The Influenza A&B Rapid Test Cassette is a qualitative, lateral flow immunoassay for the detection of Influenza A and Influenza B nucleoproteins in nasal swab specimens. In this test, antibody specific to the Influenza A and Influenza B nucleoproteins is separately coated on the test line regions of the test strip. During testing, the extracted specimen reacts with the antibody to Influenza A and/or Influenza B that are coated onto particles.
The test kit can be stored at room temperature or refrigerated (2-30°C) for the duration of the shelf life.
Clinical Sensitivity, Specificity and Accuracy
The Influenza A&B Rapid Test Cassette has been evaluated with specimens obtained from the patients. RT-PCR is used as the reference method for the Influenza A&B Rapid Test Strip (sterile swab). Specimens were considered positive if RT-PCR indicated a positive result. Specimens were considered negative if RT-PCR indicated a negative result.
