The SpeedySwab Rapid COVID-19 + Flu A&B Antigen Self-Test is a 3-in-1 at-home diagnostic kit that detects COVID-19, Influenza A, and Influenza B from a single nasal swab. This 2-pack includes two complete test kits, making it easy to test multiple household members or save a test for later use. Manufactured by Watmind USA, SpeedySwab is an FDA Emergency Use Authorized (EUA) product approved for over-the-counter, non-prescription home use.
Each test uses Lateral Flow Assay (LFA) technology and delivers results in just 15 minutes. The process is straightforward: swirl the provided nasal swab inside each nostril for 15 seconds, place the swab into the buffer solution tube, then apply 3 drops onto the test card. No laboratory equipment, prescription, or healthcare visit is required. The test is designed for self-use by individuals aged 14 and older, and can be adult-administered for children ages 2 through 13.
Since COVID-19 and influenza share many overlapping symptoms—fever, cough, sore throat, and body aches—this combination test helps distinguish between the viruses quickly, enabling earlier and more targeted treatment decisions. Early antiviral therapy is most effective when started within the first days of illness, making rapid at-home testing particularly valuable.
