n
An increase in the number of monocytes in the peripheral bloodstream. Various limits are given (for example, a total number in excess of 800/mm3, regardless of the percentage, or a total greater than 8% with the total number less than 800). In both cases, the presence of monocytosis is indicated. Monocytosis may be associated with chronic pyogenic infections, subacute bacterial endocarditis, infectious hepatitis, monocytic leukemia, rickettsial disease, and protozoan infections.

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, 950/μL is regarded as at the upper limit of normal; monocyte counts above this level are regarded as monocytosis.[citation needed]
Causes
Monocytosis often occurs during chronic inflammation. Diseases that produce this state:
- Infections: tuberculosis, brucellosis, listeriosis, subacute bacterial endocarditis, syphilis, infectious mononucleosis and other viral infections and many protozoal and rickettsial infections (e.g. kala azar, malaria, Rocky Mountain spotted fever).
- Blood and immune causes: chronic neutropenia and myeloproliferative disorders.
- Autoimmune diseases and vasculitis: systemic lupus erythematosus, rheumatoid arthritis and inflammatory bowel disease.
- Malignancies: Hodgkin's disease and certain leukaemias, such as chronic myelomonocytic leukaemia (CMML) and monocytic leukemia.
- Recovery phase of neutropenia or an acute infection.
- Miscellaneous causes: sarcoidosis and lipid storage disease.
