I see you are still very much worried and
frustrated about the seroconversion issue, although I remember that we have
discussed it (with input from my colleagues here on eTobb) on several occasions
and have been answering this very question many times. I understand your fears,
and they are somewhat legitimate, but they are also exaggerated seeing all the
facts about your specific condition, medical intervention, and repeatedly
negative test results.

If you have negative results for HIV testing
six months post initial exposure, and after having received a full course of post
exposure prophylaxis (PEP), it is medically safe to say that your results are
nearly 100% conclusive and you will not undergo seroconversion later on. This
is the case because seroconversion, which is defined as “the interval, several weeks after HIV infection,
during which antibodies are first produced and rise to detectable levels”, is known to occur in the first few weeks right after the initial
exposure to the virus. If you want my advice, I would stop worrying about the
issue if I were you, keeping in mind that reported cases of HIV seroconversion
that have occured beyond few weeks post exposure to HIV are really VERY RARE,
especially when the patient has administered the PEP course correctly. In other
words, you have almost zero chance of undergoing seroconversion and you are now
considered to have crossed into the safety zone. For future reference and as
part of health prevention measures, you need to make sure to faithfully abide
by the rules of healthy sexual habits and practices, especially when you are in
a situation where you are not fully certain of the background of your sexual
partner. This is of paramount importance to avoid acquiring any sexually
transmitted diseases, and therefore avoid putting your health at stake and the
hassle that accompanies such situations.

Having said the above, I strongly recommend
that you discuss your concerns with your treating physician, for further
reassurance, so that you would rest assured that you are now a healthy
individual who needs not to worry about the probability of carrying a
previously undetected HIV infection.
