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:

  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
  • Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
  • Ask caregivers about directions for eating and drinking.
  • Arrange a ride home. Ask a family member or friend to drive you home after your surgery or procedure. Do not drive yourself home.
  • Write down the correct date, time, and location of your procedure.

The day of your procedure:

  • Ask your caregiver before taking any medicine on the day of your procedure. These medicines include insulin, diabetic pills, high blood pressure pills, or heart pills. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital.


What will happen:

  • You may be given medicine to help you relax or make you drowsy. The biopsy will be 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. 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 more after the biopsy. Do not get out of bed until your caregiver says it is okay.


  • You have a fever.
  • You have questions or concerns about your procedure.


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.
