Bone Marrow Biopsy

Alternate Names

  • Bone Marrow Aspiration
  • Bone Marrow Test

Red and white blood cells and platelets are formed within the bone marrow. A small amount of bone marrow is removed with a needle under local anesthetic and then examined with a microscope. This exam will count the number of red and white blood cells and platelets, and examine each of these cells for size, color, and shape. Bone marrow biopsies are ordered to diagnose blood diseases such as anemias and bone marrow diseases, infections, chronic inflammatory diseases, AIDS, and cancer, and are also used to determine the stage of certain cancers.
