HIV test
Informed by recognized medical guidance
Overview
An HIV test checks for the human immunodeficiency virus (HIV) in your body. It looks for antibodies (proteins your body makes when you have HIV) or the virus itself. The test is usually done with a blood sample or an oral swab.
Key facts
- HIV tests are very accurate, especially if done after the window period (the time between exposure and when the test can detect the virus).
- You can get tested at a sexual health clinic, your GP surgery, or with a home-testing kit. Testing is free on the NHS in the UK.
- Knowing your HIV status helps you get early treatment and prevents passing the virus to others.
HIV testing is common and recommended for many people, especially those who have had unprotected sex, shared needles, or are pregnant.
Anyone can get an HIV test. It does not matter your age, gender, or sexual orientation. HIV affects people of all backgrounds.
