That looks to me like an antigen test, not a PCR test. And they are done with blood samples.
[edit] Never mind, the blood tests are for the covid antibodies. I've done a few of which, forgot which was which. But still, the same points apply. They are meant to be used with mucus, not with other things.
Many times the tests are self-administered. The last two times I have gotten a PCR test, I was told to do the swab myself and I did it with nobody watching me. Your points are irrelevant - it does not matter how these tests are supposed to work if they are so easy to game. These PCR tests are very very easy to get whatever desired result you want - negative or positive. Kind of like the 2020 Presidential election.
