Abnormalities in numbers of CD4+ and CD8+ T-cell subsets and the helper/suppressor ratio (CD4/CD8) were used very early in the AIDS epidemic to help define persons affected with AIDS before a screening test for HIV-1 was available. A low number of CD4+ lymphocytes alone or in combination with a decreased CD4:CD8 ratio and total lymphocyte count can be useful as a predictor of HIV-1 seropositivity and progression of disease.
