This measure is an indication of the strength of the immune system.


CD4 cells are an extremely important part of our immune system, HIV attacks these cells which can affect the number of them in the body.  Doctors will test a cubic ml of blood, and use this to determine the CD4 count i.e. the number of CD4 cells in the sample.  This will then allow the doctor to see how healthy a person’s immune system is. The higher the CD4 count, the healthier the immune system is.
