Thank you for your inquiry. From what we gather from the question, you were asking about the accuracy of the testing 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 does not meet the three components of the transmission equation. It does not satisfy the equation because saliva is not a bodily fluid that can transmit HIV. There is a theoretical possibility of transmission only if a large amount of blood is present with the saliva while receiving unprotected oral sex.
In regards to testing, all tests you accessed 3 months post-exposure are considered completely conclusive. The 4th generation test is considered conclusive by most HIV specialists 6 weeks post-exposure and completely conclusive 3 months post-exposure, thus the negative result you received 7 months post-exposure is completely conclusive.
Recommendation: There is no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers.
