BONE MARROW BiOPSY TEST

A bone marrow test is a way of testing cells from your bone marrow. Bone marrow is the spongy tissue inside your bones that makes blood cells. 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.
