No. As Guttermouth said, the virus has to replicate enough to be detectable. Usually that’s when symptoms begin, though you can have an asymptomatic infection too. Taking tests every day or 2x a week is more reliable … though not 100% reliable either. Lots of medical tests miss stuff or give false positives, it’s not just Covid tests.

Confirming a “case” (meaning the disease Covid-19, not just the presence of the virus SARS Cov-2) is partly clinical and requires symptoms.
An asymptomatuc infection isn’t a “case” but it’s believed to be potentially contagious anyway—not sure if this is definitely confirmed to be true but it’s believed to be—but you can be contagious in the presymptomatic (prodromal) stage, same happens with a cold, as well as low symptomatic, which may be very mild.
