Going to the local 3A and 3B hospitals for HIV antibody testing only needs the same procedures as ordinary medical treatment: registration (dermatology), medical treatment, testing on the same day, and getting the test results the next or third day.
Go to the local district and county CDC to test HIV antibody. The process is: show your ID card, enter the process for free, test, and get the results in about an hour. Personal suggestions for reference. If you have any questions, ask them.
