CD4 and viral load


Easy-to-read and illustrated information on key health monitoring tests for people living with HIV.

It’s important for all people with HIV to have regular blood tests. The two most important blood tests are for CD4 and viral load.

CD4 and viral load test results give essential information about the effect HIV is having on your body.
