Last two tests I took both took 3-5 days for results, one at a hospital and one at a test Iowa site. I’d like to get more immediate results for upcoming travel. Where I can get a “rapid result” test (I though I read Walgreens or CVS might have them) and what if I opt for a blood antibody test and have them, which I should, does that count in a similar way as a negative covid test result?
