Fast Facts About the Bone Marrow Aspiration and Biopsy

  • A bone marrow aspiration is a test to remove a small sample of fluid from inside the bone so that it can be tested and studied under a microscope.
  • A bone marrow biopsy is a test to remove a small sample of bone so that it can be tested and studied under a microscope.
  • Many patients will receive both tests at the same time, but some may only receive the bone marrow aspiration.
  • Both samples are taken from the large hip bone in your child’s lower back.
  • Your child will receive sedation medication for this test. This medication will make your child very relaxed during the test so that he or she will feel less pain and have no memory of it afterward.
  • When sedation medication is given, there are special rules for eating and drinking that must be followed.
  • Each test takes about 15 minutes, followed by 30 minutes of rest.
