PCR is close to 100%

Hard to determine given the variation in people who get tested. Someone who is getting tested randomly, it’s probably ~0% false negatives. I think the early studies were showing 20% false negatives (this was when testing was severely limited to symptomatic/known contact)

Also depends on when you get tested. One week after infection is when the tests are most accurate. Would recommend doing your own research here on PubMed or CDC docs

I’ve heard from a handful of friends that had symptoms and were initially testing negative with the nose test then positive with a blood test.

Yeah but sounds like it almost wasn’t to be...

My understanding is false negatives are fairly common. Doctors say you should quarantine the full 14 days after exposure even if you get a negative test, and hospitals may test symptomatic patients twice if the first test is negative d

This was a case of a false positive antibody test, not a false negative covid test. The antibody test is significantly less reliable than the Covid-19 test. Depending on parameters, it’s as low as 32% accurate.

And still the CDC refuses to approve more types of tests that may be faster in providing results because they need the accuracy.... 🙄

To add, bad tests are arguably worse since people may change behavior based on a test result.

False negative not uncommon given the amount of people being tested and spread of disease. To be fair though the antibody test probably has a higher chance of false positive.

I know everyone’s different but my aunt went to the hospital for very clear COVID symptoms, tested negative. Three days later she worsened, was retested and was positive. She died that night. I have the medical report. It’s perplexing.

@D2 thank you. They did keep her in the hospital but she wasn’t in a quarantined area (which raises serious safety concerns for others of course..) and it seems the treatment wasn’t aggressive enough. We’ll never really know exactly what happened. This was during the severe chaos in NYC late March.
