According to a Johns Hopkins study, this so-called gold standard RT-PCR test can have a false negative up to 20 to 66 percent of the time in even symptomatic patients depending upon the test’s timing. False negatives can be up to 100 percent on day one of exposure (asymptomatic) and down to 20 percent on day 8 of exposure (day 3 of symptoms) and then starts going up again. Statistics tell us that the false-negative rate goes up even higher as the prevalence of disease goes up, as is the case with COVID right now. A meta-analysis from Europe actually found an average false negative of 54 percent.
