Table 3: Hemoglobin Content (MCHC) Classification
Cell Type
Image
Cellular Description
Associated 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
