Bone marrow biopsy
Biopsy - bone marrow
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.
Biopsy
A biopsy is the removal of a small piece of tissue for laboratory examination.
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.
Marrow is removed in the following steps:
- If needed, you are given medicine to help you relax.
- The provider cleans the skin and injects numbing medicine into the area and surface of the bone.
- A biopsy needle is inserted into the bone. The center of the needle is removed and the hollowed needle is moved deeper into the bone. This captures a tiny sample, or core, of bone marrow within the needle.
- The sample and needle are removed.
- Pressure and then a bandage are applied to the skin.
A bone marrow aspiration may also be done, usually before the biopsy is taken. After the skin is numbed, the needle is inserted into the bone, and a syringe is used to withdraw the liquid bone marrow. If this is done, the needle will be removed and repositioned. Or, another needle may be used for the biopsy.

How to Prepare for the Test
Tell the provider:
- If you are allergic to any medicines
- What medicines you are taking
- If you have bleeding problems
- If you are pregnant
How the Test will Feel
You will feel a sharp sting when the numbing medicine is injected. The biopsy needle may also cause a brief, usually dull, pain. Since the inside of the bone cannot be numbed, this test may cause some discomfort.
If a bone marrow aspiration is also done, you may feel a brief, sharp pain as the bone marrow liquid is removed.
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).
Complete blood count
A complete blood count (CBC) test measures the following:The number of red blood cells (RBC count)The number of white blood cells (WBC count)The tota...
This test is used to diagnose leukemia, infections, some types of anemia, and other blood 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.
What Abnormal Results Mean
Abnormal results may be due to cancers of the bone marrow (leukemia, lymphoma, multiple myeloma, or other cancers).
The results may detect the cause of anemia (too few red blood cells), abnormal white blood cells, or thrombocytopenia (too few platelets).
Thrombocytopenia
Thrombocytopenia is any disorder in which there is an abnormally low amount of platelets. Platelets are parts of the blood that help blood to clot. ...
Specific conditions for which the test may be performed:
- A body-wide fungal infection (disseminated coccidioidomycosis)
-
A white blood cell cancer called
hairy cell leukemia
Hairy cell leukemia
Hairy cell leukemia (HCL) is an unusual cancer of the blood. It affects B cells, a type of white blood cell (lymphocyte).

Risks
There may be some bleeding at the puncture site. More serious risks, such as serious bleeding or infection, are very rare.

Bone marrow aspiration - illustration
A small amount of bone marrow is removed during a bone marrow aspiration. The procedure is uncomfortable, but can be tolerated by both children and adults. The marrow can be studied to determine the cause of anemia, the presence of leukemia or other malignancy, or the presence of some storage diseases, in which abnormal metabolic products are stored in certain bone marrow cells.

Bone biopsy - illustration
A bone biopsy is performed by making a small incision into the skin. A biopsy needle retrieves a sample of bone and it is sent for examination. The most common reasons for bone lesion biopsy are to distinguish between benign and malignant bone tumors, and to identify other bone abnormalities. Bone biopsy may also be performed to determine the cause of bone pain and tenderness.
