Monocytes Blood Tests

Monocytes are a type of white blood cell in your immune system. Monocytes turn into macrophage or dendritic cells when an invading germ or bacteria enters your body. The cells either kill the invader or alert other blood cells to help destroy it and prevent infection.

High monocyte counts can indicate infections, chronic inflammation, autoimmune disorders, or blood disorders like leukemia. Low counts might suggest a problem with bone marrow or the effect of certain treatments.
