HIV testing shows whether a person has HIV. HIV stands for human immunodeficiency virus. HIV is the virus that causes AIDS (acquired immunodeficiency syndrome). AIDS is the most advanced stage of HIV infection.
The Centers for Disease Control and Prevention (CDC) recommends that everyone 13 to 64 years old get tested for HIV at least once as part of routine health care and that people at higher risk for HIV get tested more often.
Risk factors for HIV include having vaginal or anal sex with someone who is HIV positive or whose HIV status you don’t know; having sex with many partners; and injecting drugs and sharing needles, syringes, or other drug equipment with others.
CDC recommends that all pregnant women get tested for HIV so that they can begin taking HIV medicines if they are HIV positive.
