I'm of the opinion that Musk was write to consider that a "wtf" result - but he could have done a much better of messaging why it was such a wtf. If a cheap test gives independently random false negative results when administered multiple times to the same human, and doesn't give independently random false positive results at an appreciable rate (which is what I've been told about that test), the test is broken for no good reason. Whoever designed it should have designed a testing protocol where you perform the test multiple times to drive the number of false negatives down - and clearly communicated that this was possible if you were looking for accurate test results. Yes, sometimes you aren't looking for accurate individual test results, e.g. if doing statistical studies, but how these tests are being used frequently you are.
