Study: Only 14% of PCR-Positive Results Were Actually Positive

A study by M. Günther et al titled “A calibration of nucleic acid (PCR) by antibody (IgG) tests in Germany: the course of SARS-CoV-2 infections estimated” published on 13 October 2025 has worked out figures that confirm the PCR tests used during the plandemic weren’t very accurate.

The paper is about 10 pages, with the main text at about 8 pages. The remaining are references.

The study takes weekly data of PCR tests and IgG tests during the period March 2020 to 2021 in Germany, and compares them.

The authors first remind the audience of the obvious, that “PCR tests merely detect the presence of fragments of viral genetic material, not necessarily an active infection”. On the other hand, IgG antibodies are detectable due to an actual immune response in infection or due to so-called vaccination.

In other words, if a randomly selected group within the population is tested for IgG antibodies, then the fraction of that group showing IgG antibodies, i.e., those who are IgG-positive, reflects the total number of people infected up to 2 weeks (or even 7 days) prior.

On any given week, tens of thousands of tests were conducted during the study period so the sample is not small. In short, the researchers found that

…on average, only approximately 14% of those who tested PCR-positive were actually infected.

Given the math and assumptions, it is possible that the figure can be as low as 11% or 10%.
