 AB    The authors assessed the characteristics of repeat human
       immunodeficiency virus (HIV) testers at publicly funded sites in San
       Francisco. During 1992-1993, 31% of all HIV tests were performed on
       persons testing negative for the third time or more. Persons with
       greater numbers of prior negative tests were less likely to test
       HIV-positive. Repeat negative testers were more likely than first-time
       negative testers to be homosexual or bisexual males, homosexual or
       bisexual injection drug users (IDUs), or heterosexual IDUs. Repeat
       testers who seroconverted were more likely to be in these same
       transmission categories than repeat testers who remained negative.
       Because of the similarities in risk profile between those most likely to
       retest and those most likely to seroconvert, attempts to limit repeat
       testing must proceed cautiously.
