Lymphocytes (a type of white blood cell) form the primary immune defense and offer protection against various infections. 1,000–4,800 cells per microliter of blood (1.0–4.0 x 10⁹/L) is the normal range for lymphocytes , which account for 20-40% of total WBCs. In children, until the immune system matures (which happens at age 7 or 8), the lymphocyte range is slightly high . A lymphocyte count that is lower or higher than this range should be evaluated to find out the underlying cause and ... Lymphocytosis refers to an increased number of lymphocytes in the bloodstream. Lymphocytes are a type of white blood cell that plays an important role in the immune system and helps in fighting off bacterial and viral infections. In lymphocytosis , high lymphocyte count in the blood may be suggestive of an evolving infection, an underlying systemic disorder (e.g., leukemia, lymphoma), or an iatrogenic cause (e.g., medication-induced hypersensitivity reactions). Lymphocytosis or High Lymphocytes: Understanding elevated lymphocyte counts. Learn causes, symptoms & diagnosis for this blood condition. Introduction: High lymphocytes , medically known as lymphocytosis , is a condition characterized by an elevated count of lymphocytes in the bloodstream. Lymphocytes are a type of white blood cell that plays a crucial role in the body’s immune system, helping to defend against infections and diseases. While an increase in lymphocyte count can be a normal response to infections, it can also indicate underlying health issues. In this comprehensive guide, we will delve into the causes, symptoms ...
