That would be completely useless, when the infection rate is around a few
percent. The signal would completely drown into the noise. No doctor would
order a test like that.
I suggest to look up some peer-reviewed reviews of the tests. Most I have
seen so far cite 5% false positive. IE, 95% specificity. Which is still in
the border of useless in most cases.
However, most recent review I found says "pooled specificities ranged from
96.6% to 99.7%".
