Look-back: preliminary experience of AABB members. American Association of Blood Banks

By mid-fall of 1986 the "look-back" process conducted by blood banks belonging to the American Association of Blood Banks was about 50 percent complete. Over one-half of the traced recipients had died; 15 percent were alive and negative for antibodies to the human immunodeficiency virus and 16 percent alive but had seroconverted. In a small number of cases physicians or patients elected not to be tested. No major problems were reported.
