We recommend that a CBC with Differential and - if anemia is the indication for the marrow examination - a Reticulocyte Count be ordered on the same day as the bone marrow collection.

Order Iron Stains separately, if desired. Additional cytochemical (e.g. myeloperoxidase, non-specific esterase) and histologic stains, including immunohistochemical stains, will be ordered by the pathologist if indicated.

Processing of bone marrow samples for histologic examination during non-routine times: the material, in 10% neutral buffered formalin fixative, will be prepared and stored in Hematology until routinely processed by Histopathology. Questions about Histopathology processing during non-routine times should be directed to the Anatomic Pathology Resident on call.
