Monocyte count represents the number of Monocytes in a microliter (cubic millimeter) of peripheral blood.
The normal white blood cells count of the Monocyte is 1100 cells/µL in infants which decreases to half that count at the first year. In adults the normal count is 300 cells/µL.
High Monocyte Count or Monocytosis is defined as the count of monocytes that exceeds 750 cells/µL in children or 500 to 600 cells/µL in Adults. The count can be increase due to the causes of Leukocytosis.
Monocytes work on fighting non-pyogenic bacteria (bacteria that doesn’t cause Pus) and Monocytosis occurs as a result of infections that caused by non-pyogenic bacteria such like active tuberculosis, subacute bacterial endocarditis, syphilis, and brucellosis.
Monocytosis can also be seen during recovery from cancer, collagen disease, agranulocytosis, and hematologic disorders.
