Claim summary · not a verbatim quotation
Kary Mullis, the inventor of the PCR method, stated that it should not be used to detect actual infections.
The finding
What the evidence shows
Kary Mullis never said PCR shouldn't be used to detect infections. The quote that circulates online making this claim actually traces back to a different writer, not Mullis, and fact checkers have found no record of him saying it. What Mullis did question was using PCR to precisely quantify how much virus is in a sample, which is a different and narrower point than saying it can't detect an infection at all.
