  1. If we know that a test (be it a COVIDtest, a pregnancy test, a cancer screening, etc) cannot be 100% accurate, if and how should those tests be used for public policy?
  2. According to the Stanford COVID linked in the above article, the specificity of a COVID test was 99.5% and the sensitivity was 82.8%. Are those levels of specificity and sensitivity high enough to be useful in deciding how to respond to COVID? What are the risks and rewards? Do you feelthat this test should be used as part of the evidence for or against responses?
