"Usually if they do have it, they're going to be OK," said Dr. Robert Garry, a Professor of Microbiology and Immunology at Tulane Medical School.

"The FDA is trying to tell us that this SARS-CoV-2 test by BD
gives some false positives. Now, it's a fairly low rate. It's only three percent." he explained.
So if your nasal swab was tested by Becton, Dickinson and Company, that same sample might need to be rerun in the lab.
"If they were using this particular test, then they'll go and they'll say, 'Hmmm, we probably need to rerun that on another assay from another manufacturer just to make sure.'"
There's nothing you can do, but the company should rerun it to confirm.

So can we subtract 3% of the total tests from the daily positives?

What's the rate on false-negatives?

So I take the daily testing totals and add 30% then subtract 3% to get the real new case total?

No, you take the all the false numbers positive or negative and add them to the positive number.
Cant have people going back to normal, we must stay in the new-normal or whatever this is.
