Hey, so about 12 weeks ago, I had a lip kiss with a prostitute, and now I'm really worried about HIV. I'm thinking about getting tested and I've heard about the combo test and maybe a Western Blot or an HIV PCR RNA test. Can you tell me which is the best option for someone in my situation?

Understanding HIV Transmission Risk from Lip Kissing

• HIV is primarily transmitted through blood, semen, vaginal fluids, and breast milk. The risk from lip kissing alone is extremely low unless there are open sores or bleeding gums.

Overview of HIV Testing Options

• Combo (4th Generation) Test: Detects both HIV antibodies and antigens, effective from 2-4 weeks post-exposure.
• HIV PCR RNA Test: Detects the virus itself, useful from 9-11 days post-exposure.
• Western Blot: Used to confirm HIV diagnosis after initial positive results.

Recommended HIV Testing Timeline

• For accurate results, the Combo test is recommended at 12 weeks post-exposure.

Best HIV Test for Your Situation

• The Combo (4th generation) test is generally preferred for screening at 12 weeks post-exposure due to its accuracy.

Next Steps and Medical Advice

• Consult a healthcare provider for testing and counseling. The risk from your described exposure is very low, but testing can provide peace of mind.
