How you prepare

By Mayo Clinic Staff

Bone marrow exams are often performed on an outpatient basis. Special preparation usually isn't needed. However, you may want to:

  • Tell your doctor about medications and supplements you take. Certain medications and supplements may increase your risk of bleeding after a bone marrow biopsy and aspiration.
  • Tell your doctor if you're nervous about your procedure. Discuss your worries about the exam with your doctor. In some cases, your doctor may give you a sedative medication before your exam, in addition to a numbing agent (local anesthesia) at the site where the needle is inserted.
