When a normocytic normochromic anemia is encountered, classify the anemia into three possible etiologies (ie, blood loss, hemolysis, decreased production). In most anemias, one of these causes is the dominant factor. However, in certain anemias, more than a single cause may play an important role. For example, pernicious anemia is predominantly due to decreased production of erythrocytes, but hemolysis adds significantly to the severity of anemia.
