Investigation
Did high-cycle polymerase chain reaction (PCR) testing materially inflate COVID-19 case counts?
In a low-prevalence setting, a substantial fraction of first positive nucleic-acid detections failed confirmation, demonstrating that positive predictive value can deteriorate even when assays are highly specific.
Among 19,597 samples, 52 were first-time positive detections; 29 confirmed on further assay testing and 23 did not. Nonconfirmation does not establish all 23 were analytically false nor a population-wide false-positive percentage.
The available false-positive and confirmation studies quantify errors in defined testing contexts but do not demonstrate that analytical false positives made up a material share of official case counts across the pandemic.
The frozen Claim requires the additional population-scale step, not merely proof that false positives existed.
