How many days covid test valid?

Question

Accepted Answer

A COVID-19 test does not have a set number of days during which the result is “valid.” It tells you whether the virus was present when you took the test; therefore, a negative result does not preclude you from becoming infected later.

If you are currently experiencing COVID-like symptoms and your home quick antigen test is negative, the infection may be too early to diagnose. Repeat the test after 48 hours. If the test is positive, you most likely have COVID-19. If you continue to experience symptoms despite negative tests, consult a doctor because another infection could be the cause.
