About Author

  • Hemoglobin
  • Red blood cell indices
    • Mean corpuscular volume (MCV) gives us a measure of red cell size; reduced MCV indicates microcytosis suggestive of iron deficiency and increased MCV is suggestive of megaloblastic anemi
    • Red cell distribution width (RDW): A high value indicates the degree of anisocytosis which is often a marker of nutritional anemia. Iron deficiency being a nutritional anemia would show cells of different sizes (small and normal sized red cells) thus increasing RDW. Thalassemia trait is a genetic condition where all red cells produced from the bone marrow are uniformly small. Thus in patients with low MCV along with normal RDW, thalassemia trait should be ruled out.
  • Peripheral smear: A good peripheral smear gives us clues to the etiology of anemia as well as information about the other cell lines.
  • Hemoglobin electrophoresis to rule out hemoglobinopathies if indicated.
