For anyone who paid any attention to the claim that the false negative rate on PCR tests exceeds 67% — more evidence that the claim is blatantly false:

https://www.nejm.org/doi/full/10.1056/NEJMoa2008457


  • 76 residents of nursing home tested
  • 48/76 test positive
  • 27/48 of positives wo symptoms

If false neg rate = 67% for people who are infected wo symptoms, the 27 that tests found should be matched by 54 that they missed.

But there are only 28 = 76-48 negatives in sample.
