4 years ago I had a possible hiv exposure and developed flu like symptoms shortly after. My physican ordered a western blot as the first test. It came in as undetermined, but showed a positive in two bands. Since this time, I have had many different types of hiv test such as the antibody and the pcr test (all have been nagative) from id's. As time passes, my symptoms have become worst and I have had a complete workup in the area of immunology, but nothing has panned out. Could these symptoms be caused by an hiv strain not being picked up in the test? Should I still be worried about hiv, eventhough I am becoming sicker?
