# Helper/Suppressor and Natural Killer Cell Profile

> This test measures specific types of white blood cells called T-cells and Natural Killer cells to evaluate the strength of your immune system. It helps show whether your body has the right balance of cells needed to fight off infections or manage immune disorders. Doctors often use these results to monitor conditions that weaken the immune system or to check how well a treatment is working. However, this profile cannot diagnose a specific disease on its own or identify the exact cause of an immune imbalance.
