White blood cells (WBCs) or leukocytes are an integral part of your immune system and help fight infections by eliminating viruses, bacteria and germs from your body. While these cells originate in the bone marrow, they circulate throughout your body. To check the number of white blood cells in your body, your doctor will order a WBC count test which is usually a part of your complete blood count. Most people are usually worried about a decrease in the number of white blood cells. However, the number of white blood cells may go up sometimes, making people ask, what causes high white blood cell count?

Normal White Blood Cells Count

There are different types of white blood cells, but are divided into two main categories – Granulocyte and Agranulocytes. Granulocytes are a combination of three types of white cells, including basophils, neutrophils, and eosinophils, all of which help destroy invading microorganisms. They have tiny granules that contain special enzymes. These enzymes digest invading microorganisms and keep them from causing an infection.On the other hand, agranulocytes include lymphocytes and monocytes. Monocytes are the white blood cells responsible for recognizing and marking invading germs, whereas lymphocytes (B cells and T cells) attack those germs marked by monocytes.

Your blood test will measure the number of all these cells. Normally, your white blood cells are between 3,700 and 10,500. You may notice a change in these numbers due to stress, exercise, and disease. Before asking the question, what causes high white blood cell count, you need to learn about the normal values of several specific white blood cells.
