Can You Do a Rat After Booster?

To find out if you are infected with COVID-19, you can take a rapid antigen test. This test will detect COVID-19 from a sample of saliva. The sample should be taken between 10 and 30 minutes after eating or brushing teeth. You can also take a sample of saliva after smoking or chewing gum. Once you have collected the saliva, you should read the results at the time specified on the kit.

If you have been infected with COVID-19, you will need to do daily RATs for at least 5 days. This will allow you to get an accurate result. You can get this test through your doctor or a health care facility. The test takes about 20 minutes and will detect all COVID-19 variants.

Compared to placebo, boosted individuals had a higher probability of achieving a positive RAT on day five. On average, they were twice as likely to be positive in a second test. The new guidelines allow for a patient to leave isolation after 5 days, if the rapid antigen test is negative.
