Experts see at-home rapid COVID-19 tests as a crucial tool in the off-ramp to the pandemic -- assuming Americans know how and when to use them.
Dr. Jen Ashton explains why poison control officials have issued warnings about the reagent used in at-home COVID-19 tests.Even if you do not have symptoms, testing is helpful after possible or known exposures, before indoor or large gatherings, prior to travel or when seeing high-risk or immunocompromised individuals.
The Centers for Disease Control and Prevention have an online Coronavirus Self-Checker that can help you decide when to test. In this scenario, it is critical to do serial tests at least 24 hours apart. Follow your test's specific instructions. Rapid test results can change quickly, so a negative test is only trustworthy for eight to 12 hours. If quarantining is not feasible while you serially test, mask and distance as best as possible.
If you test positive on a rapid or lab processed test public health officials suggest you alert close contact that you tested positive. It's possible to be contagious before symptoms develop. The CDC says if you have access to a test and want to test, the best approach is to test at the end of 5 days."If your test result is positive, you should continue to isolate until day 10. If your test result is negative, you can end isolation, but continue to wear a well-fitting mask around others at home and in public until day 10."
