Why are Bone Marrows done?
The site of puncture is cleansed with an antiseptic solution, and the patient is given a local anesthetic at the area. The site may be the pelvic bone (ilium) or the breastbone. Occasionally, another bone is selected. A special needle (a needle with a syringe attached that will create a suction) is inserted into a bone that contains marrow, and a small sample of the bone marrow fluid (called marrow aspirate) is withdrawn. The fluid is placed on a slide for microscopic examination.
There will be a needle prick and slight burning sensation with the local anesthetic. As the needle is inserted into the bone, slight pressure may be felt. There is a sharp sucking sensation as the marrow is aspirated, which lasts for a few moments.
Some bleeding may occur at the puncture site. More serious risks, such as heavy bleeding or infection, are rare. Before the procedure, the patient should be sure to tell his/her doctor what medications are being taken, if he/she any known allergies, if he/she has any bleeding problems, or if she may be pregnant.
The HPA pathologists communicate results of every test to the patient's primary physician. This is usually done within 2-3 days.
