1) Although contact with blood of an accident victim is commonly cited as a potential risk for HIV, there are few if any reports that it actually ever happened. In this case, even if the accident victim had HIV -- which is statistically unlikely -- there is no risk if her blood did not come into contact with a fresh, bleeding wound on your own skin.
2) Getting pissed at the discrepancies in information about HIV testing window is irrational. You won't find much discrepancy if you stick to scientific, professionally influenced websites. To the extent that legimitate experts disagree on advice to their patients, there are pretty good reasons for it; see the thread linked below, as well as the other thread linked in that one. In any case, with the modern HIV antibody tests, it virtually never takes more than 8 weeks to seroconvert.

That ends this thread. I won't have any further comments or advice.
