Everyone fucking misunderstands this. The original PCR test cannot "differentiate" flu and COVID because it cannot detect flu at all. It's a technical meaning of "differentiate", related to "differential diagnosis". In particular it does not mean the test will detect flu and report COVID.
It does mean they were using an unreliable testing methodology known to have a high rate of false positives without controlling for any other possible causes of the symptoms that led the individual to get tested in the first place. A differential test would at least be able to say, "You have the flu, so even though you've tested positive for COVID, that might not be what's making you sick."
But if you have the flu and not covid, you won't test positive for covid, correct?
(Unless you get a false positive, of course)
Unless you get a false positive, exactly.
