RSV + Flu A/B + COVID home test. One swab, four answers.
When winter symptoms overlap, the Flowflex Plus 4-in-1 home test detects and differentiates RSV, Flu A, Flu B and COVID-19 from a single anterior nasal swab - with results in about 15 minutes.
Is it RSV, the flu or COVID? Stop guessing.
Fever, cough and congestion look the same from the outside. This rapid antigen test detects and differentiates protein antigens from RSV, Influenza A, Influenza B and SARS-CoV-2 in one pass, so you know which virus you are dealing with - no lab, no waiting days for answers.
From 6-month-olds to grandparents
Individuals 14 and older can test themselves. For younger family members, an adult collects the sample - and the included pediatric swab guard helps keep insertion shallow and gentle for children as young as 6 months.
Ages 14+ - collect your own anterior nasal sample
Ages 6 months+ - sample collected by an adult
Pediatric swab guard included for small noses
Gentle anterior swab - about half an inch, both nostrils
Everything you need for one complete test
Every kit is a single-use test with clear bilingual instructions, and both pack sizes hold the same kit. Store it sealed at 36-86 F and grab it the moment symptoms appear.
Test cassette with a single sample well
Extraction buffer tube for your swab sample
Sterile nasal swab plus pediatric swab guard
Quick Reference Instructions in English and Spanish (timer not included)
One test or two
This test is offered in two pack sizes. The kit inside is identical either way - the only difference is how many you get, so choose based on how many people you may need to test.
1 Test
A single sealed box holding one complete 4-in-1 kit. Enough to test one person, one time, when symptoms appear.
2 Tests
Two sealed boxes, each holding its own complete kit. Test two people, or keep the second box in the cabinet for the next time someone gets sick.
How the 4-in-1 home test works
Swab
Rub the swab inside each nostril in a circular motion for about 15 seconds (around 5 rotations).
Mix
Stir the swab in the extraction buffer tube to release the sample.
Drip
Dispense 4 drops into the sample well marked with an S.
Read
Results appear in about 15 minutes. Do not read after the window in the instructions.
