I don't know much about ditan hospital. In You 'an Hospital, HIV testing is conducted in a special place. Before testing, there will be counseling similar to psychological counseling, which is probably to ask why testing is needed, the time of the last high-risk behavior, judge the possibility of infection, and give some psychological counseling and guidance. I don't need a medical card or anything. When I went there, I said that I had come for a preliminary screening, and I would ask you to fill out a form. You'd better fill in real information, at least you have a phone number. Fill in the form and draw blood, and then call about two or three days later to say the results of the preliminary screening. It doesn't matter if it's negative. If it is positive, you will ask if you want to do re-screening. There is a charge for re-screening.
This is almost the process. I hope I can help you.
