Hello Doctors,

Apologies, I accidentally hit submit before I had completed my response. Here is the complete response. Welcome to our forum and thanks for your confidence. I’ll be glad to comment. As background information, please be aware that HIV is quite uncommon among commercial sex workers in Dubai. In addition the encounter you described was condom protected. Finally the risk for acquiring HIV following unprotected vaginal sex with an untreated HIV infected partner is less than one infection for every 2000 acts of intercourse. Putting this information together, had you ask me if you needed to test, my reply would be that it was not necessary and that the encounter you describe was virtually no risk for HIV. I know of no information and cannot think of any scientific reason why letting the test process while you were driving in a car would have a negative effect on the reliability of your test results. Finally, you are correct that the oraquick HIV tests very rarely but more often than lab-based tests, fail to detect infections, particularly relatively soon after acquisition of infection. Having said that, given the facts that I have provided above and the fact that you tested 15 weeks following exposure, I would have a great confidence in your results.  While I personally do not believe it is necessary, if you choose to retest with a laboratory based test for your own assurance, virtually any test you take will provide reliable results.  I hope this information is helpful to you. If any part of my reply is unclear please feel free to use you were up to two follow ups for clarification. EWH---
