AI Overview
The FluA/FluB/SARS-CoV-2 Antigen Test is a rapid, lateral flow immunoassay used for the simultaneous detection and differentiation of Influenza A, Influenza B, and SARS-CoV-2 (COVID-19) viruses from a single nasal swab specimen. These tests are designed to provide rapid results (typically within 15-20 minutes) for individuals with symptoms of respiratory infection.
Key Aspects of the Combo Test
- Target Viruses: The test detects antigens (proteins) for SARS-CoV-2, Influenza A, and Influenza B.
Commonly Used Test Kits & Manufacturers
- BinaxNOW COVID-19/Flu A&B Combo Self Test: A widely available, FDA-authorized home test for individuals 14+ or for adults to test children aged 2-13.
- iHealth COVID-19/Flu A&B 3-in-1 Rapid Test: Provides results for all three viruses within 15 minutes.
- ViraDx SARS-CoV-2/Flu A+B Rapid Antigen Test: A point-of-care test authorized for use with anterior nasal or nasopharyngeal swabs.
- Getein Biotech FluA/FluB/SARS-CoV-2 Antigen Test: A colloidal gold-based, rapid test.
- Medomics 5-in-1 Combo Self-Test: Detects Flu A/B, SARS-CoV-2, RSV, and Adenovirus.
Important Considerations
- Negative Results: A negative result does not completely rule out infection. Due to lower sensitivity, negative antigen tests should be treated as presumptive.
- Serial Testing: For COVID-19, the FDA often recommends repeating the test 48 hours after a negative result to improve accuracy.
- Co-infection: While rare, it is possible to test positive for more than one virus at the same time, such as both COVID-19 and Influenza A.
- Disposal: All test components should be disposed of in a biohazard bag, according to local, state, and federal regulations, or per manufacturer instructions.

How to use the SARS-CoV-2 antigen test?
Open the swab wrapping - only touch the swab at the handle, do not touch the soft pad at the tip. Insert the swab into your left nostril until you feel resistance, this is usually about 2cm to 4cm. Roll the swab 5 times inside the nostril. Using the same swab, repeat this process in your right nostril.
