The PCR test-how it works and what we aren't being told. The specimen is obtained via swab, then RNA (ribonucleic acid) extracted and convert to DNA. Next this gets AMPLIFIED by PCR with specific primers then results are taken and interpreted based on the presence of viral RNA.
From their own studies & reports the test is correct at UP to 17 cycles. At amplification of 27 cycles the rate @ which the test is correct drops to 65%. Once 33 cycles is met the test is only correct 20% of the time. @ 34 cycles, there is a 0% CHANCE THAT THE RESULT IS CORRECT.
With this information they did another study which took how much its being amplified and what day after you started showing symptoms you took the test. Up to 30 cycles, only being tested on the 3rd day you began showing symptoms, the test is correct 80% of the time.
At 27 cycles on day 4, the test is correct 60% of the time.
At 17 cycles on day 5, the test is correct 33% of the time.
After day 6, there is a 0% chance the test is correct.
At 17 cycles on day 5, the test is correct 33% of the time.
After day 6, there is a 0% chance the test is correct.
So why is this important? Why am I discussing this?
Even after the CDC did these studies and understands how much the amplified cycles affects the results, and even though they know that when you get tested also affects the results.......they haven't changed the tests.

Most PCR tests are being conducted at 37 - 40 cycles! https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7185831/
