Have you taken only one at-home test? If two, were they both positive??
I think those rapid antigen tests have a higher false negative rate and a lower false positive rate.
In other words, if I got a positive test, I would take it seriously and stay home the recommended time. The rapid tests detect molecules called antigens which are made by the virus.
As your body fights the disease, antigen levels go down. So after a few days, the rapid tests may show a negative. But some people are still shedding virus after their antigen levels drop. So the waiting period is kind of a safety thing to make it less likely you're shedding virus.
