I'm really worried after visiting a barber shop because I'm afraid I might have been exposed to infections like HBV, HCV, or HIV. Could you tell me more about when I should get tested? I heard that an antibodies test for HIV can be done after 4 weeks or even up to 12 weeks, but I also read something about a p24 antigen test that can be taken after 4 weeks. How accurate are these tests? I could really use some advice right now.

Antibodies test for HIV can be performed after 4 weeks for preliminary results, but for more accurate results, it is recommended to wait for 12 weeks post-exposure. The p24 antigen test can be performed after 4 weeks to detect the HIV virus directly. It is important to follow up with healthcare provider for further evaluation and management.
