Agranulocytosis is a condition that results from failure of an individual's bone marrow to produce a sufficient quantity of white blood cells, or increased destruction of the white blood cells. As a result, the white blood cell count will be low. Acquired agranulocytosis occurs most often as a result of medications or treatments. A congenital agranulocytosis is a condition that someone is born with. Agranulocytosis usually responds well to treatment, so contact your doctor if you think you may have this condition.
Agranulocytosis can be caused by a variety of factors, including:

Talk with your doctor about the best treatment plan for you. Treatment options include the following:
Transfusion of white blood cells to replace deficit may be of benefit in certain people.
Used to treat infection that could be causing agranulocytosis or resulting from agranulocytosis.
Depending on the cause, some people may benefit from treatments with granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF).
Remove toxin/drug or treat primary disorder.
