| Bone marrow smear from a patient with a 23-month history of CML who developed a slight monocytosis, increased blasts in the blood and marrow, and an increase in marrow eosinophils with abnormal basophilic-staining granules. Cytogenetic studies showed cells with both a t(9;22) and an inv (16) abnormality. (Wright-Giemsa stain). |

Monocytosis is an increase in the number of circulating monocytes. In humans, 950/μL is regarded as at the upper limit of normal; monocyte counts above this level are regarded as monocytosis.  Monocytes are white blood cells that give rise to macrophages and dendritic cells in the immune system.
