An HIV test detects when a person is infected with human immunodeficiency virus (HIV), which can cause acquired immunodeficiency syndrome (AIDS), the most advanced stage of HIV infection. While there is no cure for HIV, there are treatments available that can help people live long, healthy lives and reduce the risk of passing it on to others.
If you answer yes to any of the questions below, it’s a good idea to get tested for HIV every three to six months.
- Are you a man who is having sex with another man?
- Have you had anal or vaginal sex with someone who has HIV?
- Have you had more than one sex partner since your last HIV test?
- Have you ever been diagnosed with, or treated for, another STI, hepatitis, or tuberculosis (TB)?
- Have you ever shared needles, syringes, and/or other injection drug equipment with others?
- Have you exchanged sex for drugs or money?
- Have you had sex with someone who has done anything listed above, or someone whose HIV status you don’t know?
It’s important to note that no HIV test can detect the virus immediately after infection. If you think you have been exposed to HIV in the last 72 hours, talk to a health care provider right away about post-exposure prophylaxis (PEP), a medication taken after potential exposure to prevent infection.
You can also ask your health care provider about PrEP, a medication that prevents HIV, to learn if it’s right for you. If you start taking PrEP, you must get tested every three months or so to be sure that you do not have HIV.
