Nope, still not exactly. Since the results of the test uses the CT value (yes I know this value is not reported to the person being tested, for the reasons I mentioned already: it varies based on the test assay being used), you can increase the number of amplification cycles as much as you want, like I said in my previous comment, it will not change the result. I guess the only thing you could manipulate is to make the cutoff so small than CT is never reached, and 100% of tests are negative. But like I also said, the standard is often 40 cycles, and depending on the tests, CT values for positive tests are typically in the 25 to 35 range, way before the cutoff.
It was most likely a lie from that ‘expert’ on that channel. Unless he’s grossly incompetent, a doctor would not make that mistake. It’s their usual MO: start with a big lie, let social media spread it everywhere without any verification, and offer a half-assed retraction much later. In case it wasn’t clear, I wasn’t talking about the people repeating it, just the ones creating it. Although I also believe that before repeating something, one should always try and verify the information.
Just to be clear, it is not chromosome 8, just a sequence present on chromosome 8. Although I read a couple papers years ago, I will never pretend I know enough about primers design to even hazard a guess here. All I know is there’s plenty of requirements for their selection. Of course, above all, it needs to be target-specific while being efficient. So all in all, a rather complex task to define these primers, and I’m not that surprised that one of them happens to match a sequence on a human chromosome.
