Bone marrow samples are usually taken from the pelvic bone or breastbone, also called the sternum. The skin over the bone is first cleaned with an antiseptic solution.

A small sample of marrow is sucked, or aspirated, into the syringe and placed on a glass microscope slide. The slide can then be examined under a microscope.
