PROVIDER INITIATED TEST - The Lymphocyte Subset Panel 3 is a blood test that evaluates key T-cell populations using flow cytometry. This panel measures both percentages and absolute counts of major T-cell subsets and includes the CD4/CD8 ratio, an important indicator of immune balance.
This test is commonly used to assess immune system status, evaluate immune dysfunction, and monitor conditions affecting T-cell–mediated immunity, including chronic infections, autoimmune conditions, or immune suppression.
The panel includes the following 5 tests:
CD3+ (Mature T Cells): Percentage and absolute count of total T lymphocytes
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 that target infected or abnormal cells
CD4/CD8 Ratio: Assesses balance between helper and cytotoxic T cells
Absolute Lymphocytes: Total lymphocyte count.
