The BD Veritor system seems to have 97.5% specificity. If it were just 1 - (0.025)^2 yeah that's pretty close to zero. btw: this new study shows that PCR can have a lot of false negatives later in the course of the disease https://twitter.com/DanielleFong/status/1327383053379964929?s=20 … https://www.fda.gov/media/139755/download …pic.twitter.com/hstAlo2U3c

Yes, and all tests are 100% false negative early on, and over 60% false negative before symptom onset. “Just wear a bandana, muh science” “Just test more, the answer is testing” “We aren’t an island run by a dictator so we should let the plague run”https://www.acc.org/latest-in-cardiology/journal-scans/2020/05/18/13/42/variation-in-false-negative-rate-of-reverse …
