The CD4 /CD8 ratio is the ratio of T helper cells (with the surface marker CD4) to cytotoxic T cells (with the surface marker CD8). Both CD4 and CD8 T cells contain several subsets. The CD4 /CD8 ratio in the peripheral blood of healthy adults and mice is about 2:1, and an altered ratio can indicate diseases relating to immunodeficiency or autoimmunity. An inverted CD4 /CD8 ratio (namely, less than 1/1) indicates an impaired immune system.
