Bone Marrow Biopsy
Bone Marrow Biopsy Introduction
Bone marrow is the spongy material found in substantial amouts in the center of most large bones in the body. The different cells that make up blood are made in the bone marrow after birth. Prior to our birth, this activity primarily goes on in the liver and slpeen. Bone marrow produces red blood cells for energy and the transportation of oxygen to the tissues, white blood cells to fight infection and support our immune systems, and platelets to help our blood clot. During the biopsy procedure (properly called bone marrow aspiration and biopsy), the liquid portion of the marrow is sampled by aspiration, and then the solid portion of the marrow and surrounding bone are taken in the biopsy.
- Why the procedure is performed: A bone marrow aspiration and biopsy procedure is done for many reasons.
- The test allows the doctor to evaluate bone marrow function. It may aid in the diagnosis of low numbers of red blood cells (anemia), low numbers of white blood cells (leukopenia), or low numbers of platelets (thrombocytopenia), or an abnormal appearance these types of blood cells.
- The doctor can also determine the cause of some infections, diagnose tumors, determine how far a disease, such as lymphoma, has progressed or spread, and evaluate the effectiveness of chemotherapy or other bone marrow active drugs.
- Where the procedure is performed: Bone marrow aspirations and biopsies can be performed in doctor's offices, outpatient clinics, and hospitals. The procedure itself takes 10 to 20 minutes with much of that time taken both cleaning the skin over and then numbing the surface of the area to be sampled.
