PROVIDER INITIATED TEST - The Lymphocyte Subset Panel 4 is a focused blood test that evaluates key T-cell populations using flow cytometry. This panel measures both percentages and absolute counts of CD4 and CD8 T cells and includes the CD4/CD8 ratio, an important marker of immune balance.
This test is commonly used to assess immune system function, monitor immune status in chronic conditions, and evaluate disorders affecting T-cell–mediated immunity, such as autoimmune disease, chronic infection, or immune suppression.
The panel includes the following 4 tests:
CD4+ (Helper T Cells): Percentage and absolute count of cells that coordinate immune response
CD8+ (Suppressor/Cytotoxic T Cells): Percentage and absolute count of cells involved in targeting infected or abnormal cells
CD4/CD8 Ratio: Assesses balance between helper and cytotoxic T cells
Absolute Lymphocytes: Total lymphocyte count
