CD4 & CD8 Lymphocyte Subsetting Test

The CD4 & CD8 Lymphocyte Subsetting test is an essential immunological test that provides crucial information about the immune system's status and functionality. It is particularly critical in managing conditions like HIV/AIDS, where it aids in gauging disease progression and guides therapeutic decisions.

CD4 and CD8 are proteins found on the surface of certain types of white blood cells known as T lymphocytes or T cells. CD4 T cells, often referred to as helper T cells, aid in immune response regulation, while CD8 T cells, also known as cytotoxic T cells, primarily function to kill infected cells in the body.
