Bone Marrow Biopsy


A bone marrow biopsy is a procedure to remove a small amount of bone marrow from inside your bone. The sample is tested for disease or infection.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • Blood tests: You may need blood taken to give caregivers information about how your body is working. The blood may be taken from your hand, arm, or IV.
  • Chest x-ray: This is a picture of your lungs and heart. Caregivers use it to see how your lungs and heart are doing. Caregivers may use the x-ray to look for signs of infection like pneumonia, or to look for collapsed lungs. Chest x-rays may show tumors, broken ribs, or fluid around the heart and lungs.
  • Heart monitor: This is also called an ECG or EKG. Sticky pads placed on your skin record your heart's electrical activity.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.

During your procedure:

You may be given medicine to help you relax or make you drowsy. The biopsy is taken from the front or back of your hip bone. Caregivers will give you local anesthesia to numb the biopsy area. Your caregiver will insert a needle into your bone. You may feel pressure and discomfort. Samples of your marrow will be sent to a lab for tests. The biopsy may take about 30 to 45 minutes.

After your procedure:

A bandage will be put on the area to keep it clean. Your caregiver will apply pressure to stop any bleeding. You may be asked to lie on the biopsy area for 1 hour or longer. This may help prevent more bleeding. Do not get out of bed until your caregiver says it is okay. Your caregiver will tell you when you can go home.

  • Pain medicine: You may be given a prescription medicine to take away or decrease pain. Do not wait until the pain is severe before you ask for more medicine.
  • Activity: Rest for the remainder of the day after your biopsy.


You may bleed or get an infection from your procedure. You may feel pain or discomfort. Without the bone marrow biopsy, caregivers may not know how to treat your illness, and your symptoms may get worse.


You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
