T- and B-Lymphocyte and Natural Killer Cell Profile
This test measures the count and percentage of three types of white blood cells—T cells, B cells, and natural killer (NK) cells—that form the backbone of immune defense. It helps assess whether your immune system has adequate numbers of these critical cells to fight infections and maintain health.
Athletes use this profile to monitor immune status during heavy training blocks, as intense exercise can temporarily suppress certain lymphocyte populations and increase infection risk. Tracking these cells helps identify whether training load is sustainable or if recovery time is needed to restore immune balance before competition or returning to intense training.
