About CD4 Count Test | Lymphocyte Count for HIV & Immunodeficiency in Fallbrook
A lymphocyte subset panel quantifies the major populations of white blood cells that direct and regulate immunity.
CD4 cells, also called T helper cells, carry the CD4 marker and coordinate much of the immune response by signaling other immune cells into action. Their concentration is a standard measure of immune competence.
The panel also reports CD8 cells, which include cytotoxic T cells that destroy infected or abnormal cells, and the CD4/CD8 ratio, a comparative index that can shift in HIV infection and other immune disorders.
Additional markers include CD16/56, which identifies natural killer cells involved in early defense against viruses and tumors, and CD19, which marks B cells responsible for antibody production. Together these values describe the balance of the immune system rather than a single isolated number.
