False Positive? Reason to worry??

Mar 9, 2011

Hey Dr Bob,

Love your work here! So here is my situation... I am a girl and had unprotected heterosexual sex twice (once condom broke, other stupid lack of judgement). I tested 20 months after the second incident. In this time I had only had sex with my boyfriend. Here were my results:

Test 1 - Reactive (one band only, not sure which one) Western Blot - Negative Viral Load - Negative

My questions are 1) If I was infected my initial test would be reactive on all bands? 2) Chances of a false negative western blot? 3) Viral load would have shown something after 20 months? 4) Should I been concerned about other possible infections which caused the false negative? 5) Should I retest?

Your thoughts are greatly appreciated! Thank you!!

Response from Dr. Frascino


A reactive screening HIV-antibody test with negative confirmatory Western Blot and undetectable viral load taken 20 months after a potential exposure is considered a definitive and conclusive HIV-negative result! HIV is not your problem. No way. No how. No additional HIV testing is warranted.
