i recently took a western blot test after 4 weeks of my unproctected sexual encounter it came out negative but i have been reading that after 4 weeks the western blot might not be accurate. is this true? i would really appreciate the response of an expert in the subject. thanks
Yes, it means that 4 weeks is too early for HIV testing for people who have had a risk.
This forum recommends a first antibody test at 6 weeks. If that test is negative, it is considered a good indication of your status and highly unlikely to change. However, a conclusive result can only be obtained 3 months after exposure.
