How is the Test Performed?
The site of puncture will be cleansed with an antiseptic solution, and you will be given a local anesthetic at the area. The site may be the pelvic bone or the breastbone.
Occasionally, another bone is selected. Then, a thin aspirating needle (a needle with a syringe attached that will create a suction) is inserted, and a small sample of the bone marrow fluid is withdrawn. The fluid is placed on a slide for microscopic examination.
