Lymphocyte Subset Panel 5 - Total Lymphocyte Enumeration

Also known as: TIMMUNPAN

Clinical Use

Use

The Lymphocyte Subset Panel 5 test plays a crucial role in evaluating individuals for primary immunodeficiencies, including severe combined immunodeficiency. It is also instrumental in monitoring immune reconstitution following transplantation. The test provides essential data by enumerating the percent and absolute cell counts of lymphocyte subsets, including CD4 helper T-cells, CD8 cytotoxic T-cells, B-cells expressing CD19, and natural killer cells. It is important for managing HIV-related conditions, with CD4 T-cell levels being used to inform decisions around prophylaxis and antiviral therapy initiation.
