A 25-year-old man is a repeat whole blood donor and recently donated blood. Routine blood donor pathogen screening came back positive for human immunodifficiency virus-1 (HIV-1), which was confirmed by western blot and viral RNA quantitation assays. His previous donation attempt was five months ago and complicated by vasovagal reaction. That incomplete unit was discarded without testing. His previous donations were 11 months ago, 17 months ago, 22 months ago and 27 months ago were either negative or non-reactive for all required infectious disease screening tests.This quiz is no longer available.
