Thank you for your inquiry. From what we gather from the question, you were asking about the negative HIV test you accessed after receiving unprotected oral sex. From the information given, this scenario is determined to be Negligible Risk (there is no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances).
The scenario mentioned above could meet the three components of the transmission equation if there is a lot of blood present in the saliva of the person performing oral sex. Please note that saliva itself is not a bodily fluid that can contain HIV positive particles. Further, also note that this risk assessment is based on the information highlighted on you being the receiver of oral sex. If you were the one performing unprotected oral sex then the risk assessment would move up to Low Risk (evidence of transmission occurs through these activities when certain conditions are met). This is because your mouth may come in to direct contact with bodily fluids that could contain the HIV virus.In regards to the testing you accessed, you can rest assured that the results are accurate. Both 3rd and 4th generation HIV tests are considered completely conclusive 3 months post-exposure. Thus, all of the tests you accessed are considered conclusive.
Recommendation: No need for further HIV testing with the scenario provided, refer to a healthcare professional for other health related questions.
