Neutropenia

An abnormal decrease in the number of circulating neutrophils. It may be cyclic in nature.

A disorder of the blood, characterized by abnormally low levels of neutrophils.

An abnormal decrease in the number of neutrophils, a type of white blood cell.

Presence of abnormally small numbers of neutrophils in the circulating blood.

A condition in which there are fewer neutrophils than usual in the blood.

Elevated levels of neutrophils in blood.

Abnormal decrease in the number of neutrophils (a type of white blood cell) in the blood; it is associated with infection, rheumatoid arthritis, leukemia, and certain vitamin deficiencies.

Condition of diminished quantity of white blood cells in the circulating blood.

A decrease in the number of neutrophils in the blood. Neutropenia may occur in a wide variety of diseases, including certain hereditary defects, aplastic anemias, tumors of the bone marrow, agranulocytosis, and acute leukemias. It results in an increased susceptibility to infections.

A reduction in the number of neutrophil leucocytes per cubic millimetre of circulating blood to a figure below that found in health. A count of fewer than 1,500 per mm} would be generally accepted as constituting neutropenia. Several infective diseases are characterized by neutropenia, including typhoid fever, influenza and measles. It may also be induced by certain drugs, including chloramphenicol, the sulphonamides, chlorpromazine and many cytotoxic drugs used to treat cancers.

The presence of an abnormally small number of neutrophils in the blood, usually less than 1500 to 2000 per microliter. Severely low levels of neutrophils predispose patients to infection.

An unusually low count of neutrophils, a kind of white blood cell, in the bloodstream leads to a heightened risk of infections. This can manifest as symptoms like fever or a sore throat. Causes of neutropenia can range from aplastic anemia and agranulocytosis to conditions like acute leukemia or the use of certain medications, including chemotherapy drugs.
