In addition to lymphocytes, there are several other types of white blood cells, including granulocytes (neutrophils), monocytes, eosinophils, and basophils. Granulocytes are usually the main white cell type in a blood sample. Lymphocytes are next, with a range of 15% to 40%. Although the blood test report gives the percentage of lymphocytes, the absolute number of lymphocytes per cubic centimeter of blood is more helpful. The absolute count is calculated by multiplying the total white blood cell count times the percentage of lymphocytes. A high lymphocyte count is defined as an absolute lymphocyte count of 4,000 or greater. Doctors call this lymphocytosis. First, be sure that you are not just looking at the percentage. Let’s say your percentage of lymphocytes is 50% (higher than usual) and your total white blood cell count is 6,000. Fifty percent of the number 6,000 is 3,000. Th
