HIV Viral Load

An HIV viral load test measures the amount of HIV RNA in your blood. If your viral load is undetectable, a person cannot sexually transmit HIV to their partner, even though the virus is still in their body.

Having a low viral load doesn't protect against other sexually transmitted infections (STIs). It's important to use protection to prevent the spread of STIs, even if your HIV viral load is low.

HIV tests are important when someone is at risk of exposure to the virus, such as after unprotected sex, sharing needles, or if they have a partner with HIV. They're also crucial for people who are pregnant, to prevent mother-to-child transmission, and for those starting or changing HIV treatment to monitor viral load and guide care.
