Table 3: Hemoglobin Content (MCHC) Classification

Cell TypeImageCellular DescriptionAssociated Diseases and Conditions
Normochromic
  • Normal MCH and MCHC (32–36 g/dL or 32–36%)
  • Small central pallor

Normal but can go along with those conditions that are seen with normocytic cells, such as:
  • Hemolytic anemias
  • Hemoglobinopathies
  • Aplastic anemias
  • Leukemias
Hypochromic
  • MCHC <32 g/dL (or <32%)
  • Red blood cells (RBCs) have a larger than normal central pallor (>3 µ in diameter) due to low hemoglobin content.

  • Iron deficiency anemia
  • Thalassemias
  • Sideroblastic anemia
  • Lead poisoning
  • Some cases of chronic inflammation
Polychromatophilic
  • Little or no central pallor
  • Reddish-blue in color
  • Slightly larger than normal RBCs
  • Supravital staining identifies these cells as reticulocytes
  • Hemorrhage-related conditions
  • Hemolysis
  • Autoimmune hemolytic anemia
  • Newborns
  • Reflective of increased bone marrow compensation
