Monocytosis is an increase in the number of monocytes circulating in the blood.

[1] Monocytes are white blood cells that give rise to macrophages and dendritic cells in the immune system.

In humans, monocytosis occurs when there is a sustained rise in monocyte counts greater than 800/mm3 to 1000/mm3.

Diseases that produce such a chronic inflammatory state:[citation needed] During these stages of extreme inflammation, monocytosis can damage tissues because it increases the activation of the immune response and prevents the inflammation from subsiding which is seen in cases where sepsis occurs.
