Re: Dry blood
WHen you have blood 'drawn" that's exactly what happens; blood from your body enters the recepticle (ie: the glass vial) and does not re-enter your body. Therefore, you cannot get HIV from whatever you saw in the glass tube. I do wonder a couple of things, however. First, how do you know the substance was on the inside of the vial and not on the outside? Secondly, how do you know it was blood? Could it have been blood on the outside of the vial that, somehow, touched a blood smear that was on the work-table?
If you really think it was blood, inside the vial, then I would request another blood test. Not because you caught HIV or anything from what you say was blood on the inside of the vial but, because, if there was blood on the inside of the vial, then the specimen was tainted and you may get a different result. chris
