Bone marrow biopsy

A bone marrow biopsy is the removal of marrow from inside bone. Bone marrow is the
soft tissue inside bones that helps form blood cells. It is found in the hollow
part of most bones.
Bone marrow biopsy is not the same as bone marrow aspiration. An aspiration removes
a small amount of marrow in liquid form for examination.
How the Test is Performed
A bone marrow biopsy may be done in the health care provider's office or in a
hospital. The sample may be taken from the pelvic or breast bone. Sometimes,
another area is used.
Why the Test is Performed
Your provider may order this test if you have abnormal types or numbers of red or
white blood cells or platelets on a complete blood count (CBC).
This test is used to diagnose:
Anemia (some types)
Infections
Leukemia
Other blood cancers and disorders
It may also be used to help determine if a cancer has spread or responded to
treatment.
Normal Results
A normal result means the bone marrow contains the proper number and types of
blood-forming (hematopoietic) cells, fat cells, and connective tissues.
