Rt PCR is more correct than the gene expert or any antibody testing. But the Rt PCR results came negative doesn't mean that u may be covid  negative. But instead it means that when u given the sample for the test u were negative or else the viral load has not become enough for u to get postive. Then u may be positive before as of the loss of smell and taste , later if the test was done after 10 days u would have become negative after the covid result came negative.

Repeat test after 14 days... Till dat time stay in isolation
