Thank you for your inquiry. From what we gather from the question, you were asking about the results of an HIV test accessed at the same time you started PEP after engaging in insertive anal sex. From the information given, this scenario is determined to be High Risk (there is evidence of transmission through these activities and are the majority of cases of transmission).
The scenario mentioned above does meet the three components of the transmission equation. It was very responsible of you to wear a condom during sex, but due to breakage of the condom the activity was unprotected for a period of time.
It was also very responsible of you to access PEP after engaging in a risky activity. PEP, if accessed within 72 hours of an exposure and used consistently and correctly for the full 28-day prescription, is an effective way to prevent an HIV transmission (1).
In regards to testing, an HIV test before a you start taking your PEP prescription can be useful if you unknowingly had HIV before engaging in the activity outlined above. With this in mind, an HIV test cannot be considered conclusive as this time because it would be outside of the window period of your most recent exposure.
HIV tests that detect antibodies (Ab) to the HIV virus have a window period that is 3 months post-exposure for conclusive results. The window period of an HIV test "resets" if you access PEP, thus the new window period after accessing PEP becomes 3 months post-PEP completion for conclusive results.
The delivery of HIV test results varies among regions, but rest assured that you will be contacted and able to access your result once it is available. I agree, waiting does suck, but while you wait for this test result, as well as the test you will access after the window period, it is best to refrain from engaging in risky behaviors to prevent the possible ongoing transmission of HIV. Please also note that a positive HIV result is not a death sentence, there are millions of people living with HIV around to world who lead long and fulfilling lives.
Recommendation: Refer to a health care provider for HIV testing outside of the window period for completely conclusive results.
