If you test negative for COVID, you often still have COVID. the PCR tests are only 80% accurate in optimal scenario (only 80% of infected people actually test positive, on the peak viral count day of infection, so the practical accuracy is more like 60%)

source on this? especially the numbers. My understanding was PCRs are typically very sensitive, and tend to stay positive for far longer than people are actively experiencing symptoms or contagious, which doesn't line up with you saying "80%" on the peak viral count day of infection.

What I'm seeing is confirmed false negative rates somewhere below like 5%, though mostly studies from earlier in the pandemic.

Rapid tests are straight trash though
