“More Than Half of Positive PCR Tests Unlikely To Have Been Infectious” – Journal of Infection
A letter to the editor published in the Journal of Infection titled, “The performance of the SARS-C0V-2 RT-PCR test as a tool for detecting SARS-COV-2 infection in the population” states the following:
In light of our findings that more than half of individuals with positive PCR test results are unlikely to have been infectious, RT-PCR test positivity should not be taken as an accurate measure of infectious SARS-C0V-2 incidence. Our results confirm the findings of others that the routine use of “positive” RT-PCR test results as the gold standard for assessing and controlling infectiousness fails to reflect the fact “that 50-75% of the time an individual is PCR positive, they are likely to be post-infectious.
Asymptomatic individuals with positive RT-PCR test results have higher Ct values and a lower probability of being infectious than symptomatic individuals with positive results. Although Ct values have been shown to be inversely associated with viral load and infectivity, there is no international standardization across laboratories, rendering problematic the interpretation of RT-PCR tests when used as a tool for mass screening.
This point has been made many times over the last 15 months. A plethora of scientific publications and scientists all over the globe have been echoing this since the beginning of the pandemic, and I’ve written about it many times since March 2020.
The statement above is why The Swedish Public Health agency has a notice on their website explaining how and why polymerase chain reaction (PCR) tests are not useful in determining if someone is infected with COVID or if someone can transmit it to others. Basically, PCR tests are not designed to detect and identify active infectious dise
