If you were exposed to COVID-19, take three home tests instead of two to make sure you’re not infected, according to new U.S. recommendations released Thursday.

Previously, the Food and Drug Administration had advised taking two rapid antigen tests over two or three days to rule out infection. But the agency says new studies suggest that protocol can miss too many infections, and could result in people spreading the coronavirus to others, especially if they don’t develop symptoms.

The new guidance applies to people without symptoms who think they may have been exposed. People with symptoms can continue using two tests spaced 48 hours apart.
