Even though they’ve been widely used across the U.S. and around the world to determine who has a positive case of COVID, PCR assays are not designed to be used as diagnostic tools, as they can’t distinguish between inactive viruses and “live” or reproductive ones.
Besides that, previously, the WHO had recommended 45 “amplification” cycles of the test to determine whether someone was positive for COVID or not.
The thing is, the more cycles that a test goes through, the more likely that a false positive will come up — anything over 30 cycles actually magnifies the samples so much that even insignificant sequences of viral DNA end up being magnified to the point that the test reads positive even if your viral load is extremely low or the virus is inactive and poses no threat to you or anyone else.
What that means in plain language is that the more cycles a test goes through, the more false positives that are reported.
Now, with the WHO’s lower PCR thresholds, it’s practically guaranteed that COVID “case” numbers will automatically drop dramatically around the world.
