AIDS Counselling for Low-Risk Clients

Among the reasons for false positives are the presence of cross-reacting antibodies (Stine, 1996); false positive reactions with non-specifi cally “sticky” IgM antibodies (Epstein, 1994, p. 56); false positives from samples placed in the wrong wells; and contamination of wells containing negative specimens by positive samples from adjacent wells. In addition, heat-treated, lipemic, and hemolyzed sera may cause false positives; false positive results have been reported to occur in 19% of haemophilia patients and in 13% of alcoholic patients with hepatitis (George & Schochetman, 1994, p. 69). People who have liver disease, have received a blood transfusion or gamma globulin within six weeks of the test, or have received vaccines for infl uenza and hepatitis B may test false positive, as well (Stine, 1996, p. 333).
