"Is it a reasonable conclusion that I would not meet the npep prescribing guidelines because given the facts I've outlined my risk of transmission is low?"
Yes, if it were me I would not even consider PEP in the situation you provided.
"Do either of you have a quantitative sense of the risk of transmission in the circumstance I described? Say we assume the worst and that my partner is HIV positive, given the presence of blood what kind of range of probability am I looking at."
There is no reason to assume that she is positive, but if she was, the risk would be 1 in 2000.
However, most likely she was not. The HIV prevalence in women in NYC is no higher than 1 in 250 (which is higher than the national average of 1 in 1000). If we assume she is more likely to be infected due to her occupation, the chance she was infected would still probably be in the neighborhood of 1 in 100.
Thus, your overall chance of catching it would be in the neighborhood of 1 in 200,000.
I did not mean to scare you about seeking a local doctor's opinion- however that is usually standard advice on the Expert Forum in situations where HIV prevalence is elevated.
If it were me, I would just get tested, but not worry too much about it.
My area is NYC. Is it a reasonable conclusion that I would not meet the npep prescribing guidelines because given the facts I've outlined my risk of transmission is low? I really appreciathe the answers thus far. Do either of you have a quantitative sense of the risk of transmission in the circumstance I described? Say we assume the worst and that my partner is HIV positive, given the presence of blood what kind of range of probability am I looking at
You would not qualify for PEP by todays guidelines on nPEP.
"Would it be advisable to seek PEP as a precaution?"
That is a question for your doctor as it falls into medical territory; nobody here can really advise on that (there are no doctors on this forum).
I suspect that you would probably not qualify for the reason that your partner is not confirmed HIV positive (unknown status). However, my understanding is that the criteria for PEP depends on where you live, the HIV prevalence in the region, etc., so you really need to seek a local doctor's opinion on that if you are concerned, rather than get an answer from an on-line forum.
Please also note that PEP is only effective if you begin treatment within 72 hours.
Calling your doctor's answering service and trying to get a telephone consultation might be a next step to consider.
