CD 4/CD 8

CD4 and CD8 proteins are crucial cell surface markers that play pivotal roles in the immune system. CD4 is primarily found on helper T cells, while CD8 is present on cytotoxic T cells, aiding in immune responses and maintaining overall immune function. This test measures the levels of CD4 and CD8 cells in your blood, which are important for assessing your immune system function, thereby serving as an aid in the management of HIV patients. The CD 4/CD 8 test helps monitor the progression of HIV infection and assess the immune status of HIV-positive individuals; evaluate certain autoimmune disorders, such as lupus or rheumatoid arthritis, and assess immune reconstitution after bone marrow transplant. This test is recommended if you have been diagnosed with HIV or are at risk for HIV infection; have symptoms of autoimmune disorders or blood cancers, are undergoing treatment for an autoimmune disorder, or have received a bone marrow transplant.
