These are pretty much irrelevant issues given the zero risk exposures you describe.
In the US, most labs still do not routinely use 4th generation tests (i.e. 3rd gen antibody, plus p24 antigen). In any case, since you did have both antibody and p24, your results are reliable at 1 month.
That will end this thread. I won't have any further comments or advice.
Hi Dr Hunter,
Thanks again for your fast reply. You have answered my questions just now. Btw, p24 antigen must combined with 3rd generation elisa test? i'm not sure the hospital is using 3rd generation elisa test or 2nd? do u think now year 2012 still have ppl use 2nd generation? i called to the hospital before but she don't know and answered me they use a machine to analyst. I know it is combi test from the report stated hiv antigen/antibodies test look for p24 antigen and antibodies. omg.
I'm not sure I understand your question. However, a negative duo (combo) test 1 month after the last encounter is valid for that event and for all exposures before that time.

Hi Dr,
Thanks for your fast reply. You calm me down a lot.Another question.
Duo test done after 28 days can conclude any exposure on week 4,5,6,7,8,9,10,11,12 ? i means if someone with high risk event and he have few sexual encounter on week 4,5,6,7,8,9,10,11,12 and he do the test after 28 days last exposure. Does it conclude all his previous sexual encounter? Sorry for the complicated question.
Welcome to the forum. Thanks for your question.
We get many questions on this forum from men about massage and various non-penetrating sexual experiences in massage parlors. The answers are always the same: most massage workers do not have HIV; and even if they do, HIV is never transmitted if a bare penis (no condom) does not enter another person's vagina or rectum (and maybe the mouth, very rarely). In other words, the ONLY way to catch HIV in a massage parlor is to have unprotected intercourse while there. As those commens suggest, you are not at risk for HIV from the events you have described.
You did not need HIV testing. However, your negative duo test a month after your last exposure is additional proof you were not infected. There are no medical conditions or medications that delay HIV antibody production or otherwise interfere with HIV tests.
Finally, the answer to your last question is obviously "no". Nobody has seen anyone get infected after such exposures, because it doesn't happen.
I hope this has helped calm your anxieties. If you continue to visit massage parlors, be prepared to use a condom in the event you have vaginal or anal sex. Otherwise, do not worry about catching HIV.
