Lymphocytes are types of White Blood cells. It can be in the form of either T-cells or B-cells. Helper T-Cells is also known as CD4. While the Suppressor T-Cells are called also CD8. These tests help in enumerating the CD4 and CD8 cells and evaluating their ratio. This test is used to monitor the Auto-Immune Diseases like HIV.

Why CD4/CD8 Ratio Test?


T cells are lymphocytes recognized by their cell surface markers as CD4 (T helper cells) or CD8 (killer cells) subtypes. CD4/CD8 Ratio helps to monitor patient immune system status. It compares the proportion of CD4 – T helper cells to CD8 –T killer cells. This value helps to predict the likely course of the disease and the outcome of the treatment. These test results are helpful in the diagnosis of certain conditions like the impaired immune system, immunodeficiency, or autoimmunity. A low CD4+/CD8+ ratio is indicated in disease conditions such as tuberculosis etc. While AIDS reflects an altered CD4+/CD8+ ratio (when compared with the normal population), thus indicating morbidity and mortality. Thus in chronic immune system disorders and/or diseases, the disease progression leads to the drastic decline of cell-mediated immunity and hence becomes more susceptible to opportunistic infections.
