What is a lymphocyte subset panel?

Lymphocyte Subset Panel 4 – This panel separately reports CD4+ T cells (CD4) and CD8+ T cells (CD8) in the blood, as well as a calculated CD4/CD8 ratio. This panel may provide information of the immune status of individuals living with HIV.

What is lymphocyte enumeration panel?

This test is designed for enumerating the percent and absolute cell count of lymphocyte subsets in lysed whole blood. Whole blood is added to fluorochrome-labeled antibodies that bind specifically to cell surface antigens on lymphocytes.

What is lymphocyte subset panel 5?

Lymphocyte Subset Panel 5 – This panel is used to measure CD4+ T cells (CD4) in the blood (absolute CD4 cell count, Í4, absolute lymphocytes). The CD4+ T-cell (CD4) count is the most valuable indicator of immune status in HIV-infected individuals.
