Rapid Antigen COVID-19 Tests: Update on Authorized and Unauthorized Tests
Rapid antigen tests (RATs) provide a cost-effective and convenient way to screen for COVID-19 in the comfort of your own home. A simple kit, complete with a nasal swab, solution, and easy-to-read result tray, can provide a quick ‘yes’ or ‘no’ when you are wondering if your sniffles are due to seasonal allergies or the latest variant of SARS-CoV-2 (the virus which causes COVID-19). As such, RATs have proved a valuable tool for managing our new so-called pandemic life.
In addition to the eight free rapid antigen tests (RATs) available from the government, RATs can be purchased over the counter at local or online pharmacies or retailers such as Walgreens, CVS, Target, Amazon, or Wal-Mart.
The U.S. Food and Drug Administration (FDA) has continued to grant emergency use authorization of rapid antigen tests for COVID-19 as new data emerges. Recently, several RATs have been authorized; conversely, several have had their letters of emergency use authorization revoked.

Recall that rapid antigen tests may be negative very early on in an infection. In the case of exposure to COVID-19, it is recommended to check a RAT 2-3 days after the exposure (if you remain asymptomatic) and then continue to test every day or every other day for six days hence. If you have been exposed to COVID-19 and are experiencing symptoms, a negative RAT test may be a false negative and should be followed by a PCR (if available).
