It was a mistake for you to insist on the
Western blot. Had you come to my clinic, we would have refused your request. A negative
ELISA, by itself, is 100% proof against HIV if done mor ethan 6-8 weeks after the last possible exposure. WB was not designed as a primary test -- it's only value is in confirming a positive ELISA.
And yes, "this is the case in [your] situation" -- since it is the case in everybody's "situation".
