Classification of Normocytic Anemia

By William Aird

There are many causes of normocytic, normochromic anemia. It helps to use an organizing framework that sorts causes into big, then smaller buckets:

  • Hypo- vs. hyperproliferative
    • Hyperproliferative:
      • Bleeding
      • Hemolysis
    • Hypoproliferative:
      • Nutrition
        • B12 deficiency
        • Folate deficiency
        • Fe deficiency
      • Inflammation
      • Organ dysfunction
        • Liver
        • Kidney
        • Endocrine
        • Bone marrow (BM)
