I am not a doctor. What is the difference between testing positive for having Covid and testing positive for having had Covid in the past? If there is a difference, how long after testing positive for having Covid does it take to convert to testing positive for having Covid in the past? Thanks.
Going by memory here which may be faulty. Yes, I have experience.
You need to test within 2 weeks of symptoms for CURRENT infection. PCR test.
Wait a month after to get anti-body testing for PAST infection. Too early might not be enough time for the anti-bodies to appear.
I’ve had many PCR tests, one of which was pos. Since my whole circle got it, my husband and son were able to anti-body test about 2 months after sick and we’re pos.
