CD?8: Cytotoxic T cells involved in defeating infections and abnormal cells. Elevated CD?8 is common during HIV infection ? Who Should Take This Test PLHIV seeking regular immune system monitoring Individuals undergoing immunosuppressive treatments such as for organ transplants or autoimmune disorders Patients needing assessment of T?cell reconstitution (e.g., post-transplant) or primary immunodeficiencies
