HIV antibody testing and posttest counseling in the United States: data from the 1989 National Health Interview...

To see how successful human immunodeficiency virus (HIV) counseling and testing efforts have been in testing the United States population, particularly among those at increased risk for HIV infection, we analyzed data from the 1989 National Health Interview Survey. Twenty percent of the NHIS sample (or, in terms of the general US population, an estimated 36 million persons) reported having been tested for HIV antibodies, mostly through blood donations. Although persons with increased risk of HIV infection had been tested and counseled at a much higher rate than the general population, the majority of this group had not yet been tested.
