I had unprotected sex with a Chinese woman on December 17 last year. I took PEP on December 19. She was tested with instn for 60 seconds 7 days later and the results were negative. The fourth generation HIV duo test was used for the second time after 29 days, and the results were negative. Now that I have completed the PEP course of 28 days for two weeks, can I have a HIV RAN test? Hope to get your opinions! Thank you.
