I took tests before going to the doctor in Russia. I don't know if my tests were confused with someone else's, or somehow messed up, but in Russia I had to redo and the results turned out to be completely different, twice in different labs. With the indicators that this laboratory gave me, as the doctor said, they no longer walk on their own feet.
As a result, it turns out that I paid for something incomprehensible, and also rolled into Russia in vain, because I didn't have time to hand over everything I needed on the spot. I don't advise anyone else to do anything else.
