The OP that I responded to said there was 1 test for Covid-19 and the antibodies which is incorrect as I stated. You injected yourself into the thread saying I was wrong when in fact I am right. Your last reply is an attempt officiate from the context from my post. Simply put, a person will develop the antibodies 2-3 weeks after they recover. Further, my quote, "Those who have recovered won't test positive unless they're still in the 10-20 quarantine" is correct. What I am referring to is that those who THINK they have recovered, may still test positive because they're still in the 10-20 day quarantine period for which I also stated that's why the Big 10 has a 21 day quarantine. The 10 day quarantine the ACC has may not be sufficient in some case because there is no exact number of days. It's a minimum of 10. So, a person or player such as Trevor Lawrence could think he's clear because he feels better after 10 days, but may continue to test positive for 20 days which is 3 weeks from the infection date.
