Based on the article below that I located... It looks like the labs are only reporting the positive cases and not the negative cases. Doesn’t say the test are flawed or the labs are faking the numbers
Yep all the results are skewed, it's all BS. More people getting tested so obviously there will be more positives, but they don't tell you the infection rate...which is going down. There was another lab that "accidentally" reported all antibody positives as active COVID positives.
“The largest lab companies don’t appear affected by the reporting discrepancy. Quest Diagnostics in Tampa has reviewed 540,816 tests with 11% positive. Laboratory Corporation of America has processed 455,836 tests with 12% coming back positive and Bio Reference Laboratories has checked 360,286 tests with 13% positive. AdventHealth’s lab processed 103,000 tests with an 11% positivity rate.”
