Lymphocytes are a type of white blood cell (WBC) essential for the immune system, comprising T cells, B cells, and Natural Killer (NK) cells. In a Differential Count, the lymphocyte percentage reflects the body's ability to mount a specific immune response, particularly against viral infections and intracellular pathogens. They are responsible for antibody production and cell-mediated immunity.

Why Context Matters
Lymphocyte percentages can be transiently altered by acute emotional or physical stress, recent vaccinations, or corticosteroid use. A second opinion or follow-up is often necessary to distinguish between a benign viral reaction and primary hematologic disorders like Chronic Lymphocytic Leukemia (CLL).
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
