Original Note:
PCR tests ran above 33 cycles do not generate false positives. A positive test with a high Ct value may indicate a test from someone who had a very small amount of detectable viral RNA on their initial swab, and may not be infectious or have ongoing active infection. https://fullfact.org/health/cycle-threshold-values/ https://www.mcgill.ca/oss/article/covid-19-critical-thinking/covid-19-pcr-test-reliable-despite-commotion-about-ct-values
