- bone marrow aspiration and biopsy
- listen (bone MAYR-oh AS-pih-RAY-shun ... BY-op-see)
A procedure in
which a small sample of bone marrow (soft, sponge-like
tissue in the center of most bones) and bone is removed. A
small area of skin and the surface of the bone underneath
are numbed with an anesthetic. Then a special wide needle
is pushed into the bone. A sample of liquid bone marrow is
removed with a syringe attached to the needle. The syringe
is then removed and the needle is rotated to remove a
sample of the bone and the bone marrow. Both the bone
marrow and bone samples are sent to a laboratory to be
looked at under a microscope.
