The FDA suggestion of doing two tests to reduce the percentage of false positives (since you can't rule out cross-reactivity with another coronavirus) looks like a good idea for broad testing.
Of course this means higher costs.

- lbeltrame 6y agoThat can't be discounted, but if you have two tests that target different epitopes of the virus (hence, independent), the probability of them being wrong at the same time is p_false1 * p_false2 (probability of independent events), hence much lower.
