What is the Monocyte Count Test?
There are five types of white blood cells – basophils, neutrophils, eosinophils, lymphocytes and monocytes. Monocytes are responsible for typical white blood cell functions, including immune system function. However, monocytes are also specific to certain diseases and conditions like monocytosis, monocytic leukemia and monocytopenia.

The monocyte count test is not ordered as a standalone measurement. Doctors will order a WBC (white blood count) panel that measures levels of all white blood cells.

Normal Value Range

  • Negative Pregnancy Adult: 0.1 to 0.7X103/mm3X103µl or 0.1 to 0.7X109/L
  • Pregnancy Trimester One: 0.1 to 1.1X103/mm3X103µl or 0.1 to 1.1X109/L
  • Pregnancy Trimester Two: 0.1 to 1.1X103/mm3X103µl or 0.1 to 1.1X109/L
  • Pregnancy Trimester Three: 0.1 to 1.4X103/mm3X103µl or 0.1 to 1.4X109/L

If the blood test measures higher than normal numbers of monocytic white blood cells it could be an indication of heart attack, monocytic leukemia or brucellosis. Conditions that cause inflammation, such as allergies or asthma, can also cause a rise in white blood cell counts, including monocytes.
