Just get the antigen test rather than the PCR test. Last May, our group of 4 got the PCR test on a Monday. On Tuesday we had three negative results and one positive. On Wednesday, the positive guy went for a rapid antigen test and received a negative result. It's the PCR test that is sensitive enough to produce a positive result long after recovery. It was funny, b/c our local health department kept calling my friend the entire time we were in St Martin!
