After how many days pregnancy can be confirmed by urine test

As the Omicron variant continues to spread wildly, millions of people are worried they have been exposed—and are desperate to find out if they are infected. But in many areas, at-home rapid antigen tests are difficult to find, and PCR tests—if an appointment is available—can take days to return a result.

So if you can get your hands on a precious test, when is the best time to use it for the most accurate result?

With the original strain of SARS-CoV-2, the coronavirus that causes COVID, the amount of virus in the body—known as viral load—generally reaches its peak five to seven days after exposure, says Gigi Kwik Gronvall, an immunologist at the Johns Hopkins Bloomberg School of Public Health.

The Centers for Disease Control and Prevention and many state health departments recommend that exposed people who have been vaccinated wait until this time to take a test after contact with someone who has COVID to be certain that a negative test is truly negative because the highest viral load will provide the best chance
