Don't worry about this. I'm from the AIDS laboratory of the CDC. The reagents used in blood stations are very sensitive and have weak specificity. The purpose of this is to avoid missed diagnosis, but the disadvantage of this is that the false positive (not positive for AIDS testing) is relatively high. At this time, they will be sent to the AIDS laboratory of the Municipal Center for Disease Control and Prevention, and the AIDS laboratory will conduct another screening (AIDS fourth-generation reagent, which can detect AIDS antigen), and most of them can be screened out at this stage. If it is still positive, further confirmation tests will be conducted. In our city, there are many blood stations that can be positive, but few of them are diagnosed as positive, unless they donate blood after having high-risk behaviors before, because in many people's minds, if blood donation is adopted, it means good health and blood donation examination is free.

Aids patients are also a relatively small circle. It is a crime for AIDS patients to have unprotected sexual contact with others when they know that they have AIDS. People in the CDC will also tell them how to avoid infecting others. So your chances of being infected are very low. Wait patiently for the result, and hope that this will not happen in the future.
