A bone marrow biopsy involves removing a small sample of the bone marrow inside your bones for testing. Bone marrow is a soft tissue in the center of most large bones. It makes most of the body's blood cells.
The biopsy is done using a small needle inserted into the bone. The bone marrow tissue is removed and then sent to a lab and checked under a microscope. You may be given a shot (injection) of a local anesthetic before the biopsy. This will numb the area so you don’t feel any pain.
A bone marrow biopsy is usually done if your healthcare provider thinks that you have a problem making blood cells. A specialist called a pathologist examines blood and bone marrow samples in a lab. The pathologist can check your bone marrow for any of the following:
