[quote=Anonymous]False positives are a real thing. That was the case for us when DD tested positive several weeks after she had COVID. We decided to confirm with PCR. Two successive PCRs were negative. [quote]Using summary results for symptomatic people tested during the first week after symptoms began, if 1000 people with symptoms had the antigen test, and 50 (5%) of them really had COVID-19: • 45 people would test positive for COVID-19. Of these, 5 people (11%) would not have COVID-19 (false positive result). • 955 people would test negative for COVID-19. Of these, 10 people (1.0%) would actually have COVID-19 (false negative result).[/quote] https://www.cochrane.org/CD013705/INFECTN_how-accurate-are-rapid-antigen-tests-diagnosing-covid-19#:~:text=At%205%25%20prevalence%20using%20summary,5%20cases%20will%20be%20missed.[/quote]
