The sequence you pointed is one primer, not what you are trying to detect. You have a pair of primers for PCR tests. Both need to bind to a specific region for the amplification to occur. So, in this case, even if indeed this sequence can be found on chromosome 8, the other primer (also listed in your picture) would prevent the amplification to start. In other words, if you were feeding only human DNA alone to this test, it would always stay negative, as no amplification would be possible. I kept it short, but you can find all the details in the link below.
Confirming my original comment as it is completely incorrect. You don’t set the CT value to run the test, as it is a result of the test. Most assays run 40 cycles, and the CT is when what you are trying to detect becomes visible. It usually occurs way before the final cycle, which means you could run hundreds of cycles, and the CT would stay the same. So no, you cannot manipulate the CT value when running the test.
However, depending on the test assays, what is considered a positive CT can change because of different gene target or methods. It is calibrated against known samples, and part of the testing procedure for all assays. It doesn’t change once it is determined, and the test assays approved for laboratory use. So, again, it cannot be manipulated.
This lie started with a right wing channel (OAN or Newsmax, can’t remember) and was amplified by this crooked lawyer in Canada. And many months later, people who don’t check, still repeat it.
