This test measures the amount of monocytes in blood. Monocytes are a type of white blood cell (WBC). This test is used to evaluate and manage blood disorders, certain problems with the immune system, and cancers, including monocytic leukemia[1].
Normal moncoyte values. Monocytes account for between 4 and 8% of white blood cells. In a blood test their value can be found in the section on Complete Blood Count with the other types of white blood cells. Normal monocyte values are between 1000 and 4500 cells per ml. Therefore, if your monocyte count is between these two values, you can rest assured that it is a normal count and everything is fine. High monocyte values When monocytes exceed normal values it is almost always due to infections caused by viruses or parasites, such as the following: However, a high monocyte count can also be caused by a chronic inflammatory disease, tuberculosis, tumours or leukaemia. A high monocyte count is called monocytosis.
