georgiagail responded:
There are cases of false positive HIV screening test results. The attached article discusses the causes of some of these:

Typically a positive screening result is followed by a second test, known as a Western Blot. If both tests come back "reactive" (i.e., positive) the person is assumed to be HIV positive. If the Western Blot comes back non-reactive, the person is considered to be HIV negative with an initial false positive screening result.

I hope this makes sense.

how do i know what test they ran?
georgiagail replied to kimbub's response:
How about calling your physicians office and asking if this was the ELISA or the Western Blot (likely the first).

One question you need to ask yourself is "could I be at risk for HIV"...based on a past exposure? For example, recent unprotected intercourse, sharing of IV drug needles?

It not, then the risk is not there.

So...could you be at risk?
