Report today:  Thousands of BRits may be false negatives.


Well, duh, if you don't have a perfect correlation and make a cutoff you are going to have false negatives and false positives.  The question is:  where do you set the cutoff?  I assume that the worst thing is a false negative.  For a false positive you test again.  For false negatives?  What?  Anyone know?

Billw, there has never been a consensus on the balance of where cutoff line should be.  


We tend to blow off the false positive: you just test again.  Sure.  But then you spent the money for two tests and might have caused someone to go into isolation unnecessrily.  Think of a scenario please where a false positive is far more serious than a false negative.
