Filters Content type: News, Editors' picks, About HIV Topic: CD4 count

CD4 cells are the most important cells in the immune system. A type of test called a CD4 count tells you how many CD4 cells there are in a small sample of blood. The more there are the better. Decisions about when to start treatment are often based on the CD4 count.
