"during the early pandemic period, only about 14% of PCR-positive results represented true infections, meaning 86% were false or non-infectious detections. The study examined data from the ALM laboratory consortium, which conducted ~90% of Germany’s PCR tests, and compared week-by-week PCR positivity with IgG antibody data from the same labs. "
