Monocyte and granulocyte disorders

Neutropenia or neutropaenia, is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood.

Agranulocytosis, also known as agranulosis or granulopenia, is an acute condition involving a severe and dangerous leukopenia (lowered white blood cell count), most commonly of neutrophils causing a neutropenia in the circulating blood.

Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 4.

Eosinopenia is a form of agranulocytosis where the number of eosinophil granulocytes is lower than expected.

Monocytopenia is a form of leukopenia associated with a deficiency of monocytes.

The hypereosinophilic syndrome (HES) is a disease characterized by a persistently elevated eosinophil count (≥ 1500 eosinophils/mm³) in the blood for at least six months without any recognizable cause, with involvement of either the heart, nervous system, or bone marrow.

Autoimmune neutropenia is a form of neutropenia which is most common in infants and young children where the body identifies the neutrophils as enemies and makes antibody to destroy them.

Basopenia (or basocytopenia) is a form of agranulocytosis associated with a deficiency of basophils.

Bandemia refers to an excess of band cells (immature white blood cells) released by the bone marrow into the blood.

In medicine, granulocytosis is the presence in peripheral blood of an increased number of granulocytes, a category of white blood cells.

Neutrophilia (also called neutrophil leukocytosis or occasionally neutrocytosis) is leukocytosis of neutrophils, that is, a high number of neutrophil granulocytes in the blood.

Basophilia is a condition where the basophil quantity is abnormally elevated (more than 1010 basophils per liter of blood).

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