Sternal Tap

Sternal Tap is the removal by suction of fluid from the soft, spongy material that lines the inside of most bones.

Purpose of Sternal Tap

This test is used to diagnose leukemia and other disorders that affect the blood. It may help determine if cancers have metastasized (spread). It is also helpful in diagnosing some types of anemia and infections.

How a Sternal Tap is 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needle with a syringe attached that will create a suction) is inserted, and a small sample of the bone marrow fluid is withdrawn.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.
