STORY AT-A-GLANCE
> A suspiciously high number of laboratories in Florida are reporting 100% of COVID-19 viral tests as positive. It appears many labs may be submitting positive results only, omitting negative results altogether

> In Florida, while each positive test result is counted as a “case,” a single person may have two or more test results. So, one infected individual can be counted as two “cases”

> Some states have also excluded negative test results from their reporting, thereby giving us an incomplete and misleading picture of the spread of the disease across the country

> If the prevalence of infection in the community is 1%, and you have a test that’s only 99% specific, then about 50% of all positive tests will be false positives

> The BD SARS-CoV-2 Reagents for the BD Max System test has a 3% false positive rate. The Cellex antibody test, which has a reported sensitivity of 94% and specificity of 96%, delivers unacceptably high rates of false positives

In regards to the two cases issue, it is actually the number of times they are test. If they are tested every 2 or 3 days in order to report back to work, they are reported every single time they test. So if a person is on 2 weeks quarantine, they test 4 times positive, then 4 positive test results in the numbers. Multiply that by how many workers are being tested in order to return to work and you might get a better handle on how many new infections we are really getting.

I note that link is to this person's site: Joseph Michael Mercola is an American alternative medicine proponent, osteopathic physician, and Internet businessman, who markets dietary supplements and medical devices, some of which are controversial

plus, it makes no difference to our everyday life here. if things were other than reported int he news, then the developers would be opening up more activities and they are not. the danger is real.

Yes, I posted a thread on this two weeks ago, there are still many labs reporting 100% positive tests which skews the percent positive number upward. Even so, it appears to be trending downward.

Florida's positive testing rate may not be accurate
