Re: expired Covid test kits and false positives

4. You're assuming degradation always results

In a lack of signal. You could be right. I offhand don’t know why degradation could also not cause an increase in signals.

I guess I view the tests as having a certain amount ‘noise’ in their results even when new, and that noise results in both false positives and false negatives. As the tests degrade over time, the noise level increases, the errors increase, but that applies to all errors.
