Let's talk about false positives: there seems to be no solid estimate regarding common Cov-19 tests. I've seen numbers from 40% to 85% in papers suggesting at least a high number, some of which will probably be sloppily classified as "asymptomatic" cases.
- robocat 7y agoI read that the false positive rate is extremely low (below 1%). False positives are not a huge problem when you are only testing people with symptoms. False positives would only become a problem when you are doing a large number of tests on people who have no symptoms (e.g. 1% of 1 million people when close to none have the virus). I think your numbers are the detection rate: false negative rate is high (up to 40% for early tests).
