Your doctor has determined that you need a procedure called a "Bone Marrow Biopsy." Please follow any instructions given to you by your doctor or his/her nurse. This pamphlet contains general information and should not replace any direction given to you by your doctor.
A Bone Marrow Biopsy removes a small amount of fluid and cells from inside the bone (bone marrow). Bone marrow is where your body makes red blood cells, white blood cells and platelets. This procedure is done to check for problems with any of the blood cells made in the bone marrow. The sample collected will be sent to a lab and examined under a microscope. Additional tests will be performed on your sample to determine if there are any abnormalities.
There are a number of reasons why you may be advised to have this test. The test may be done to determine the reason for a low or high number of red blood cells, white cells or platelets. It may be done to investigate various blood disorders or types of blood cancers. It may also be done to collect cells needed for genetic testing.
Bone marrow samples are taken from the top of the pelvic bone. You will be asked to lay on your stomach or on your side during this procedure. The skin over the punctured site will be cleansed with a special antiseptic solution and some local anesthetic (numbing medication) will be injected to ease your discomfort. A needle will then be pushed through your skin and into the bone.
During the aspiration (removal of fluid and bone marrow), you may feel a quick, sharp pain in your bone or down your leg. This only lasts a second or two and the pain stops as soon as the sample is removed. Usually after the aspiration is completed, a core biopsy will be obtained. This is done by inserting a larger needle through the same puncture site. Instead _ of suction, there may be a twisting or grinding sensation. A small plug of bone is then removed with this special needle.
This test is usually performed as an outpatient here at the office.
There are no restrictions for eating or drinking prior to this test. Please arrange for someone to drive you home after your procedure. Occasionally, you may be given medication to help you relax during your Bone Marrow Biopsy.
Please talk to you doctor about any concerns you may have regarding the need for this biopsy, the risks, how the test will be performed and what the results might indicate. You will be asked to sign a consent form.
After the biopsy you will be asked to remain lying down for 10 to 15 minutes and light pressure may be·applied to the site to stop any bleeding. A bandage will be applied to the biopsy site and this area should remain covered for 24 hours after you test has been performed. You should also avoid soaking in bath tubs or swimming pools for 48 hours after your biopsy. You will need someone to drive you home after your procedure. The biopsy site may feel sore for several days and you·may experience bruising. Ice can be placed on the biopsy site and Tylenol may be used for any discomfort you may have.
Please call our office if you experience any additional symptoms or have any concerns after your procedure.
