Full Answer

A count of less than 1,000 lymphocytes per microliter of blood in adults, or less than 3,000 lymphocytes per microliter of blood in children, is known as lymphocytopenia, or lymphopenia, says the National Heart, Lung and Blood Institute. If an adult has a lymphocyte count significantly higher than 3,000 per microliter of blood, he has lymphocytosis.
