Course Description: The role of the laboratory in diagnosing microcytic anemia cannot be overstated. The most common cause of anemia worldwide is iron deficiency which can easily be identified through the work of the hematology and clinical chemistry laboratories. However, there are other causes of microcytic anemia that must be differentiated in order to ensure the proper treatment. This course will provide a brief review of normal erythrocyte maturation, morphology, and function, as well as the classification of anemia before looking more closely at the classification, etiology, and specific diagnostic tests used to properly identify the cause of microcytic anemia.
