QuickStats Percentage of Adults Aged >18 Years Who Had Ever Been Tested for Human Immunodeficiency Virus (HIV),* by Age Group and Sex --- National Health Interview Survey, United States, 2007

In 2007, overall, 36.6% of adults aged ≥18 years reported ever being tested for HIV. For both men and women, the percentage of persons who ever had an HIV test was highest among adults aged 25--34 years and 35--44 years and lowest among adults aged >65 years. The percentages who had ever had an HIV test were higher for women than men in age groups 35--44 years and below, not significantly different for men and women at ages 45--64 years, and higher for men than women at ages ≥65 years.

* Based on responses to the following question: "Except for tests you may have had as part of blood donations, have you ever been tested for HIV?" Persons who refused to respond or who answered "Don't know" (approximately 5% of respondents combined) were not included.

Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. population.
