CD4 and viral load

This illustrated leaflet gives basic 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.

A CD4 count tells you how many CD4 cells there are in a drop of blood. The more there are, the better. Viral load measures how much HIV there is in a drop of blood.
