The validity of self-reported HIV antibody test results.

Three hundred twenty-six participants in a multisite study were initially tested for human immunodeficiency virus (HIV) antibody and later interviewed; 228 were recent drug injectors and 38 were HIV positive. Later, 264 (81%) correctly reported their test results, 9 (3%) gave incorrect results, and 53 (16%) said either that they had not been tested or that they did not know the results. The predictive values of positive and negative self-reports were 90% and 98%, respectively (P less than .01).
