Binaxnow Covid Test Walgreens (2025)

FAQs

How accurate is the BinaxNOW COVID test? ›

Another study, published in 2022 by Naval Medical Research Center researchers, found a sensitivity and specificity of BinaxNOW of 69.7% and 71.0%, respectively.

Where We Stand. After testing more than 20 at-home COVID-19 tests for ease of use, convenience, and speed, we recommend the iHealth COVID-19 Antigen Rapid Test. It's easy to use, convenient and gives clear results.

Rapid antigen (self-test or at-home) tests are now covered by insurance, as required by the federal government. If you are uninsured, many test sites in the Commonwealth test uninsured individuals for free. Visit TestingLocator.cdc.gov to find a no-cost COVID-19 testing location near you.

Positive Result: If you see two pink/purple lines (one on the top half and one on the bottom half), this means COVID-19 was detected. Look very closely!

Testing has been completed to support a shelf-life (expiration date) of up to 22 months. The BinaxNOW™ COVID-19 Antigen Self Test, part number 195-160 or 195- 180, may now have a longer than labeled product expiry date. All BinaxNOW COVID-19 Antigen Self Test kits currently have a twenty-two-month expiry date.

Too many or too few drops can lead to an incorrect or invalid test result. How does the test work? The N-protein of the SARS-CoV-2 virus reacts with the coating of the test line and leads to a color change, i.e. a red line appears. If the sample does not contain SARS-CoV-2 virus , no red test line (T) appears.

After a positive test result, you may continue to test positive for some time. Some tests, especially NAAT tests, may continue to show a positive result for up to 90 days. Reinfections can occur within 90 days, which can make it hard to know if a positive test indicates a new infection.

The COVID-19 infectious period can vary, but most people are considered infectious from 48 hours before their symptoms start and can be infectious for up to 10 days.

PCR tests are more accurate than the other type of COVID-19 test, called an antigen test. PCR tests may be done at home. But they are more likely to be done by a healthcare professional and processed in a lab.

If your antigen test (such as an at-home test) result is positive, you may still be infectious. Continue wearing a mask and wait at least one day before taking another test.

When should you test for COVID after exposure? ›

When You Should Test for COVID-19. If you have symptoms, test immediately and then test again per the instructions if your first result is negative. If you were exposed to someone who has COVID-19 and you do not have symptoms, wait at least 5 full days after your exposure before testing.

A: All at-home OTC COVID-19 diagnostic tests are labeled with an expiration date printed on the outer box or package. Generally, tests should not be used beyond this expiration date.

In the setting of a nonhealthcare workplace outbreak of COVID-19 with high attack rate (62.3%), we found that BinaxNOW was a useful adjunct to rRT-PCR testing. BinaxNOW showed NPA and PPV of 100%.

Key Takeaways. How long COVID-19 stays in the body varies from person to person. Generally, people are no longer contagious about 10 days after symptoms first develop. COVID vaccination appears to significantly shorten infection times along with the length of time a person is contagious.

Invalid Result: If there is no Control Line and Sample line, only the Sample Line or the Blue Control Line does not turn pink/purple the assay is invalid. Repeat the test if the result is invalid.

We've conducted lab analyses and tests on the Omicron variant from live virus, including from the first U.S. omicron case, and BinaxNOW detected the virus in all tests we performed at equivalent sensitivity as other variants.

The percentage of rapid antigen tests with false positive results is reported to be less than 1%.

After clinician tests were collected, patients then performed and interpreted their own rapid test. The sensitivity of clinician and self-collected rapid testing was very good and relatively similar at 88.2% (clinician) vs. 83.9% (patient); notably, sensitivity was much lower in asymptomatic cases (63% [clinician] vs.

A COVID-19 diagnostic test can have a false-negative result. This means that the test didn't show you have the virus even though you do. You risk spreading the virus to others if you don't take care, such as wearing a face mask, when you're near other people.
