After 9 weeks of high risk, I went to Haidian District, Beijing to donate blood, and the next day I sent a text message saying that the test passed. Can I rule out AIDS?

Don't doubt the blood center yet, your behavior is very dangerous, because there is a window period of 3-6 months after HIV infection. In the window period, HIV antibody can't be detected, but it will be contagious. I sincerely hope that you are not infected, but if you are infected, you have already killed a patient. Using blood donation to detect HIV violates the principle of voluntary blood donation and is prohibited. I suggest you take the initiative to call Beijing Blood Center to inform the above situation, hoping to recover this bag of blood in time.
