*'''Stress leucogram''' mediated by the production or administration of glucocorticoids. This phenomenon is also characterised by [[Neutrophilia|neutrophilia]], [[Eosinopenia|eosinopenia]] and [[Lymphopenia|lymphopenia]].

*'''Chronic inflammatory processes''', including chronic bacterial infections and chronic inflammatory diseases of the liver (chronic hepatitis and cholangitis) and pancreas ([[Pancreatitis - Dog and Cat|chronic pancreatitis]]). Serum fibrinogen may also be elevated in such chronic processes and there may be a variable neutrophilia depending on the level of active inflammation.

*'''Granulomatous disease''' results in monocytosis as monocytes are recruited to contain certain types of bacteria (namely ''[[Mycobacteria spp.]]'', ''[[Nocardia|Nocardia spp.]]'', ''[[Actinomyces species - Overview|Actinomyces]]'' and ''[[Rhodococcus equi]]'') or foreign objects.  Severe granulomatous disease may also result in hypercalaemia as differentiated macrophages acquire the ability to produce activated vitamin D metabolites.

*Certain types of monocytic or myelomonocytic '''chronic myeloid leukaemia''' may result in the presence of large numbers of monocytes in the blood.
