Where to buy FlowFlex at-home rapid COVID tests

Check your symptoms at home with this one-test antigen home kit.

FlowFlex now offers an at-home rapid test to screen your COVID-19 symptoms at home. Its high accuracy rate for positively diagnosing asymptomatic individuals led the FDA to advise needing only one test. It’s a cheaper test than many of its competitors at around $10 a kit. However, it doesn’t pair with an app to display your results, potentially making it less convenient for some.

How it works

FlowFlex’s rapid COVID test operates similarly to other at-home tests. Swab the inside of both nostrils, then insert the swab into the tube of solution and swirl. Squeeze four drops of the solution onto the test card, and wait 15 minutes for the results.

Your test card will show either:

  • One top line — indicating a negative test result
  • One top line and one bottom line — indicating a positive test result
  • One bottom line or no lines — indicating an inconclusive result

If you receive an inconclusive result, you will need to buy another kit. FlowFlex includes one test per kit.

Failing to follow the instructions can result in inaccurate results, so carefully read all paperwork with your kit before testing.

What’s included in the test

The FlowFlex at-home rapid COVID test contains:

  • One test card
  • One nasal swab
  • One dropper tube with chemical solution
  • Package instructions

How FlowFlex compares to other at-home tests

Two factors give FlowFlex an edge over its competitors.

  1. It’s cheaper than competitors. FlowFlex comes in at $10, where many other tests can cost twice as much or more.
  2. It requires only one test. Most at-home kits require you to take the test twice, usually 24 to 48 hours apart.

FlowFlex doesn’t pair with an app on your phone as tests like BinaxNow does. An app helps to keep your results on your device as a convenient way to report results to your workplace.

Like the majority of at-home rapid tests for COVID-19, FlowFlex is an antigen test, which looks for molecules found on the virus. However, a few at-home tests, like Cue, are molecular tests that experts say tend to be more accurate overall.

What the FDA and CDC say about FlowFlex

The US Food and Drug Administration authorized the FlowFlex COVID-19 Home Test for emergency use in October 2021. Emergency use allows companies to bring their products to market faster in unusual circumstances, such as during a pandemic.

The FDA requires the majority of at-home kits to test more than once, usually 24 to 48 hours apart — a practice called “serial testing.” This practice helps to control for false negative results in asymptomatic people with COVID-19. However, FlowFlex’s high accuracy rate with positively diagnosing asymptomatic individuals led the FDA to clear it for single testing.

The FlowFlex kit does not meet the CDC’s travel requirements for testing.

What to do if you test positive

If you test positive using the at-home kit, follow the instructions provided. The company recommends contacting your healthcare provider and isolating to avoid spreading the virus.

Your healthcare provider will work with you to determine how best to care for you based on your test result along with your medical history and symptoms.

Consult the CDC’s guidelines on exposure and quarantine for further guidance.

About at-home COVID rapid tests

At-home rapid COVID tests — also called antigen tests — detect protein fragments specific to SAR-CoV-2. It’s a convenient way to test for COVID-19 without needing to leave your home or find a testing center. It reports results in as little as 15 minutes but isn’t as accurate as a PCR test.

Rapid tests are most accurate for those experiencing symptoms of COVID-19. While the false-positive rate is very low, the false negative rate is up to 50%.

Can I get a free at-home COVID test?

In December 2021, the White House announced a plan that includes nine actions to protect the health of Americans in the wake of spiking Delta and Omicron variants. Among them was expanding access to free at-home testing regardless of health insurance status.

Details aren’t yet in, but options are expected to include:

  • Reimbursement of the cost of at-home test kits for those covered by private health insurance.
  • Free at-home tests through community and testing sites, including health clinics and centers across the US.
