Performance of the OraQuick Rapid Antibody Test for Diagnosis of Human Immunodeficiency Virus Type 1 Infection in Patients with Various Levels of Exposure to Highly Active Antiretroviral Therapy

Abstract
With oral mucosal transudate and serum samples from 101 human immunodeficiency virus type 1 (HIV-1)-infected subjects and 100 HIV-1-negative volunteers, the OraQuick HIV-1 test demonstrated 100% specificity and 96% sensitivity. Four false-negative subjects, who were characterized by early initiation of effective antiretroviral therapy, demonstrated waning serum anti-gp41 titers and Western blot band intensities.
