I am a nurse that routinely conducts STD exams and just got through drawing blood for a confirmatory test on a patient that was told he/she had tested
positive on a test at the local plasma
donation center. The patient brought in a form letter from this center which had several selections with a check mark beside HIV 1/2. I called the plasma center and inquired as to what HIV test they run on donors. The person who I talked to at the plasma center was supposed to call me back, but did not.
