name
descriptionA diagnostic bone marrow aspiration may be used to determine the cause of unexplained low or high blood cells counts, including too few or too many white blood cells (WBCs) (leukopenia or leukocytosis). A variety of disorders and conditions may be identified, monitored, and/or staged with this process. For example, leukemia is a cancer of the blood cells which results in the excessive production of one type of white blood cell, resulting in the presence of large quantities of cells that do not function as normal ones do and the absence of the typical distribution of white blood cells.
