Do you know how to interpret results?
 |  | By Anisa Arsenault, Associate Editorial Director | | Whether your holiday plans are behind you or you're still gearing up for some gatherings, it's a good idea to take a COVID test. At-home tests are more popular than ever. Over 60 have been authorized by the FDA. But do you know how to use them or how to interpret their results?
We've put together a handy guide about what you should know. | |  | | Types & Accuracy | At-home tests and rapid tests are not necessarily the same thing. Yes, you can take a rapid (antigen) test at home and get results in minutes. But you can also take a more accurate PCR test at home and mail your sample to a lab to get results. This is sometimes referred to as an at-home collection kit instead of an at-home test.
In general, when a person is infected with COVID-19, PCR tests can accurately detect the virus 99% of the time. This is called the sensitivity of the test. The sensitivity of rapid tests is lower, at 90%. | | | | PCR vs. Rapid Tests | If you're sick and wondering whether your symptoms are caused by COVID-19, a rapid test can give you that answer quickly, without putting other people in line at a clinic at risk.
Opt for a PCR test if you're symptomatic and need testing before a medical procedure, if you're exposed to someone with COVID-19, or if you still feel sick after testing negative from multiple rapid tests. | | | | When to Take a Test | | False-negative results can happen if you test too soon. Experts recommend testing three to five days after any known COVID exposure. If you're exhibiting COVID symptoms, you should test as soon as possible. | | | | If You Test Positive | | Even if you don't think you have COVID, you should take an at-home positive test result seriously. Start by isolating yourself from others. Next, contact a healthcare provider to let them know you've tested positive and to learn next steps. If you took a rapid test, a confirmatory PCR test may be recommended, especially if you think it's unlikely that you were exposed to COVID-19. | | | | Best At-Home Tests | | Our editors researched dozens of at-home COVID test kits and evaluated them for test type, swab type, result speed, and pricing. Each of the tests chosen was determined to be the best based on these factors. | | | | | | | | | | |  |     | You are receiving this newsletter because you subscribed to the Verywell Health newsletter.
