Human Immunodeficiency Virus in Adults and Adolescents Testing Algorithm
Human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS). Screening in asymptomatic individuals and early identification of active disease are critical. Preferred testing involves the fourth generation screen with reflex, which follows the CDC recommended algorithm for the laboratory diagnosis of HIV infection. All adults and adolescents older than 13-64 years should be offered one-time screening. High-risk patients should be screened more frequently.
