A few questions help us personalize your report.
Lymphocytes are the immune cells responsible for adaptive immunity — including B cells (which produce antibodies) and T cells (which directly kill infected or cancerous cells). Elevated lymphocytes can signal a viral infection, certain leukaemias, or autoimmune conditions; low lymphocytes are associated with HIV, high-dose steroids, autoimmune disease, or severe nutritional deficiency. Tracking the lymphocyte-to-monocyte ratio provides additional insight into immune activation and systemic inflammation.

High lymphocytes indicate viral infections like EBV, CMV, or chronic lymphocytic leukemia. Low lymphocytes occur with HIV, corticosteroid therapy, or severe stress.
Standard range is 1.0-4.8 K/uL. Functional practitioners target 1.5-3.0 K/uL. Age-related lymphocyte decline accelerates after 60.
