Bone marrow biopsy
Definition:
Bone marrow is soft tissue found inside some of the larger bones in the body. The marrow produces platelets and red and white blood cells. A biopsy is a method of removing a small tissue sample from the body to have it examined under a microscope and possibly analyzed by other tests. Alternative Names:

How the test is performed:
The bone marrow biopsy may be done in the health care provider's office or in a hospital. The sample is usually taken from the hip bone. The skin is cleansed, and a local anesthetic is injected to numb the skin. The biopsy needle is then inserted into the bone. The core of the needle will then be removed, and the needle is pressed forward and rotated in both directions. This forces a tiny sample of the bone marrow into the needle. The needle is then removed. Pressure is applied to the biopsy site to stop bleeding, and a bandage is applied. An aspirate may also be performed, usually before the biopsy is taken. After the skin is anesthetized, the aspirate needle is inserted into the bone, and a syringe is used to withdraw the liquid bone marrow. If this is performed, the needle will be removed and either repositioned, or another needle may be used for the biopsy. How to prepare for the test:
Inform the health care provider if you have allergies to any medications, about which medications you are taking, and if you have bleeding problems. The health care provider should also know if you are pregnant. You must sign a consent form. For infants and children: The preparation you can provide for this test depends on your child's age and experience.
