Counseling and testing (CT) are important components of state and local human immunodeficiency virus (HIV)-prevention programs (1). Analysis of national data sources indicates that HIV-antibody tests are obtained from a variety of testing sites, including private physicians, hospitals, and outpatient clinics (66.7%), and publicly funded sites (33.1%) (2). This report uses data from CDC's 1993 Behavioral Risk Factor Surveillance System (BRFSS) to examine variations in rates of use of private and public HIV CT sites by state.
