    This is quite something. Julia is completely misrepresenting the results, presented here Of the 9,376 students in the bottom row, there were 10 positives (1 pooled test). This equates to a FP rate of 0.1% https://twitter.com/JuliaHB1/status/1336723631066451968 …pic.twitter.com/8QJn7Tvgb0

        More broadly, the testing methodology used here is pooled testing, which by design sacrifices specificity because a single false positive requires retesting of a larger group of people

        If we looked at the false positive rate in the pooled testing program as a whole, this has so far happened a single time, with a specificity of ~99.7%pic.twitter.com/0MksT9IEiH

        0.1% is even more impressing seeing as they were blanket testing everyone and not picking symptomatic cases like normal testing.

        It might be quite something, but it's sadly also quite usual.

        They JHB and Tice both also overlook the fact it was testing of samples taken from asymptomatic people, and omitted to state they there were actually 9 +ves from 71 cases that were symptomaticpic.twitter.com/I0Ksg4qrLA

        I just signed up to Twitter to say 2 things: 1. I really enjoy following your feed. 2. As far as I see, there were _10_ pooled tests and not 1 pooled test: 9,376 students, 1,937 pools, 10 positive pools.
