The article is also a month old, but that is not my issue with the 70% figure. My issue is that, without knowing the base rate of the sub population being tested, and without considering there will be more false negatives if tests are only carried out on a population based on the assumption that the subject is likely to have covid at the time of testing.
You disbelieve the 70% figure ?

What base rate are you talking about ?

Do you know if they did or didn't take the unknown base rate into consideration ?
