evidence: Instagram posts claiming "Court Holds PCR Covid Tests 97% Inaccurate" began appearing at the end of May 2024. These posts, published by accounts with tens of thousands of followers (see examples here, here, and here), contained a screenshot of an article on the website Hal Turner Radio Show. The website has a record of publishing inaccurate information and conspiracy theories. Its owner Hal Turner was convicted in 2010 for threatening to assault and murder federal judges over handgun bans. [...] This finding, which was cited as part of the basis for the Lisbon court ruling and for Turner’s claim, doesn’t mean that PCR tests are "97% inaccurate". What it means is that the smaller the amount of viral genetic material in a sample (and the higher the Ct), the smaller the chance that live virus—a marker of contagiousness—is present. [...] In conclusion, a Portuguese court’s conclusion that PCR tests are "97% inaccurate" is based on misinterpreted findings. The letter by Jaafar and colleagues didn’t report that PCR tests have a 97% chance of producing false-positive results. Instead, their findings suggest that positive PCR results at high Ct values—indicating very little viral genetic material—may be a sign that a person likely isn’t contagious.
