A negative result means the test did not detect viral antigens, but it does not rule out infection. If you have symptoms and your first test is negative, test again in 48 hours because antigen tests are less sensitive than molecular tests. A positive result strongly suggests an active COVID-19 infection, so you should isolate and contact a healthcare provider for guidance.

Serial testing means testing yourself repeatedly over several days. This increases the chance of detecting an infection early and helps reduce the risk of transmitting COVID-19 to others.

For people with symptoms within the first seven days of onset, the test is authorized when used at least twice over three days with 48 hours between tests. For people tested for epidemiologic reasons, use at least three times over five days with 48 hours between tests. Repeat testing is not needed if you already have a positive result.

Acceptance varies by organization, so you must check with the group requiring proof. The BinaxNOW Self Test is for personal use only and does not produce a verified or documented result.

Antigen tests are more accurate when taken multiple times across several days. Repeating the test improves accuracy and reduces the chance of false results. Full performance data is available in the Healthcare Provider Instructions for Use on the manufacturer’s website.

The manufacturer monitors viral mutations closely and has analyzed multiple variants, including Delta and Omicron. Current analysis predicts no impact on test performance with these variants.

Molecular tests (PCR/NAAT) detect viral genetic material. Antigen tests detect viral proteins. Antigen tests are very specific but less sensitive, meaning positive results are usually reliable, but a negative result does not rule out infection. A healthcare provider can advise if a molecular test is needed after a negative antigen result.

Yes, each box lists an expiration date. It should not be used after that date.

Ongoing stability testing has supported a shelf life of up to 22 months. Some kits may be valid beyond the printed date. You can check your lot number on the manufacturer’s website to confirm its updated expiration.

The test is authorized for individuals 15 years and older, and for children ages 2 to 14 when an adult collects the sample.

Yes, store the test between 35.6°F and 86°F. Short periods outside this range are generally acceptable. When using the test, ensure all components are at room temperature.

No, the test does not create a digital or official record. Results are read visually on the card between 15 and 30 minutes after performing the test.

Yes, the test is HSA/FSA-eligible. Check with your insurance provider if you need confirmation for your specific plan.

No, the swab has a soft foam tip and should not hurt. It may feel tickly or slightly uncomfortable. If you feel pain, stop the test and seek medical advice.

Yes, you will need a timer or watch. Wearing gloves during the test is recommended.

No, this antigen test only detects active infections. Antibody tests are used to identify past infections.

Reimbursement policies vary. Contact your insurance provider to determine whether your plan covers at-home tests.
