  • Clinical Indications
  • Bone Marrow Procurement
      • Bone Marrow Procurement
      • Bone Marrow Procurement: Supplies
      • Bone Marrow Procurement: Aspirate
      • Bone Marrow Procurement: Core Biopsy
      • Aspirate: Optional Immediate Bedside Smear Preparation
      • Core Biopsy: Optional Immediate Bedside Imprint Preparation
      • In adult patient populations, what is the preferred site for the collection of bone marrow aspirates and biopsies?
      • The core biopsy should be red, with grossly identifiable bone particles.
  • Bone Marrow Core Imprints
      • Bone Marrow Core Imprints (Touch Preparation)
  • Bone Marrow Aspirate Preparation: Anticoagulated Sample
      • Anticoagulated Aspirate Sample: Bone Marrow Layers
      • Occasionally, the percentages of the bone marrow "crit" are difficult to discern and re-centrifugation might help.
  • Bone Marrow Aspiration: Laboratory Technical Preparation
  • Bone Marrow Clot Preparation
      • Bone Marrow Clot Preparation
      • The clot section includes the remaining particles from the aspirate and red blood cells. Three levels, usually cut at 3 microns thick, are stained wit...
  • Bone Marrow Core Biopsy
      • Bone Marrow Core Biopsy
      • Bone marrow core biopsy specimens do NOT allow for the best evaluation of bone marrow cellularity, cellular distribution, and cellular relationships a...
  • Iron Stain on Spun Bone Marrow Aspirate Fat-Perivascular Layer
      • Iron Stain on Spun Bone Marrow Aspirate Fat-Perivascular (F-PV) Layer
      • In order to not disrupt fat cells, alcohol fixation of the fat-perivascular (F-PV) slide used for iron store evaluation with the Prussian blue iron st...
  • Iron Stain on Bone Marrow Concentrate (Myeloid Erythroid Layer)
  • Immunohistochemical (IHC) Stains
  • Special Stains
      • Reticulin Stain
      • Prussian Blue Iron Stain
      • Bacterial and Fungal Stains
      • Amyloid Stain
      • Amyloid deposits are most commonly identified on core biopsy specimens, but may also be seen on aspirate smears.
      • Which stain is commonly utilized to detect iron in bone marrow specimens?
  • Histochemical Stains
      • Enzyme Stains
      • The application of enzyme/histochemical stains by the pathologist will NOT change the classification of the disease in a bone marrow biopsy specimen s...
