I would like to add that the FDA is not allowing testing kits that measures only antibodies because it feels that this may lead to false positives; ie, you can have antibodies from exposure to C19 without "catching C19" or being contagious yourself; however, what the FDA won't accept is that if you combine this test with highly correlated symptoms (fever, cough, loss of taste) then it becomes more likely you are positive for C19. Additionally, the type of test that the FDA is preferring (evidence of virus sheddin) pretty much eliminates startups with innovative testing solutions because only the larger labs with larger budgets (Abbot, J&J) has access to the proper equipment (very expensive) to meet these requirements.
