BTNX Rapid Response Influenza A+B Rapid Antigen Test
Lateral Flow Test Cassette - Results in 8 Minutes - Swab or Aspirate Specimens

The BTNX Rapid Response Influenza A+B Test Cassette is a rapid lateral flow immunoassay for the qualitative detection of influenza A and B antigens. It aids in the rapid differential diagnosis of influenza A and B viral infections, detecting and differentiating the two types in a single test with results in 8 minutes. The test accepts nasopharyngeal swab, nasal swab, throat swab or nasal aspirate specimens, giving clinicians and laboratory staff flexibility in specimen collection. 

In the clinical study reported in the product insert, the test showed an overall accuracy of 92.8 percent for influenza A and 96.7 percent for influenza B. Each kit includes everything needed to run 20 tests, including test cassettes, sterile collection swabs, extraction reagent and tubes, dropper tips, a workstation, and non-viable positive control swabs for both influenza A and influenza B. Test cassettes are supplied in individually sealed pouches and can be stored at 2 to 30°C. BTNX Rapid Response tests undergo regular evaluation using proficiency samples from the College of American Pathologists (CAP). This test is for laboratory use.
