How long is the international standard of AIDS window period?

It's been ruled out. There's no need to test it. If you are really scared, you should have a test within six months. Actually, it's not necessary The so-called three-month window period was set many years ago, and now it can be determined in six weeks. Of course, some CDC and hospitals will tell you that it will take three months to rule it out, which is shirking responsibility. If you are a doctor, you will tell your patients the same thing ... If they tell you, it will be ruled out in half a year or a year, and everyone will understand each other.
