Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the HIV testing you accessed after engaging in intercourse with a condom that broke. From the information given, this scenario is determined to be Low Risk (evidence of transmission occurs through these activities when certain conditions are met).

The scenario mentioned above does meet the three components of the Transmission Equation since bodily fluids potentially containing HIV could have had direct access to your bloodstream. It was very responsible of you to access HIV testing after engaging in a risky activity. Since you accessed testing outside of the window period (12 weeks for the 4th Generation test and 3 months for the antibody (ELISA) test), you can be assured that your negative results are completely conclusive. It is also important to note that the index values for the tests you received cannot be compared. They are completely different types of tests and were conducted on different days. As long as the index value is below a certain value (depending on the test), the negative result is reliable. If the index value is ever close to a potential positive result, the laboratory would redo the test and often ask for another blood sample to ensure the results are accurate.

If you are continuously engaging in high risk activity, there are biomedical approaches such as PrEP and PEP that can help lower your risk of acquiring HIV. Refer to your physicians for further information.

Recommendation: HIV testing has been accessed outside of the window period. Refer to a health care provider for other health related questions.
