Wow. So we are supposed to trust these tests as accurate.
So much for trusting the people that we think know about this disease.
Surprise!
PS: And don't limit that to just this disease, every test you do has a chance of false positive/negative. Almost no test is prefect.
And actually, I'd say 5% is pretty good compared to some of the other numbers I've heard. I'd take and trust that... though, for something as high stakes as NFL is doing, I might want two test.
But I heard one of the worst companies had one with like 40+% error rate, were no good US company that knew what they were doing, wanted them. But I'm willing to bet they still sold, either to people that don't know what they're doing, or 3rd world areas.
