A bone marrow aspiration and biopsy removes a small amount of bone and a small amount of fluid and cells from inside the bone (bone marrow). It is often done to find the reason for many blood disorders and may be used to find out if cancer or infection has spread to the bone marrow.
Examination of the bone marrow is necessary to make the diagnosis of myeloma and to estimate the extent of the disease. A bone marrow aspiration and biopsy is the procedure to collect a sample of bone marrow. 1  Two types of bone marrow samples are taken: liquid bone marrow (an aspirate) and solid bone marrow within bone core (a biopsy). The test is usually performed on the back of the hip bone.
