==Overview==
The differential diagnosis for hemolytic anemia is broad and includes a variety of conditions that affect [[red blood cells]]. [[Nutritional deficiencies]] and [[Thalassemia|thalassemias]] are important components of the differentiation. Certain laboratory tests and physical exam features can help to distinguish these conditions. The treatment of these conditions are quite different, so it is important to distinguish hemolytic anemia from other causes of [[anemia]] or other conditions that present similarly.

Overview

The differential diagnosis for hemolytic anemia is broad and includes a variety of conditions that affect red blood cells. Nutritional deficiencies and thalassemias are important components of the differentiation. Certain laboratory tests and physical exam features can help to distinguish these conditions. The treatment of these conditions are quite different, so it is important to distinguish hemolytic anemia from other causes of anemia or other conditions that present similarly.
