Hello, the HIV test of Haikou CDC is in 1 building, but you have to find the person in charge of HIV infection department first, and he will give you a test number. The doctor won't ask your name, phone number and address, and at most he will know your high-risk situation. Then you take the test number to 1 building to draw blood. Generally speaking, the CDC conducts unified testing on Tuesday. So I suggest you take the exam on Monday so that you can know the result as soon as possible. Going on Friday and not knowing until next week will only make you suffer for a few more days.
