Spherocytosis is an auto-hemolytic anemia (a disease of the blood) characterized by the production of spherocytes - red blood cells (RBCs), or erythrocytes, that are sphere-shaped, rather than bi-concave disk shaped. Spherocytes are found in hereditary spherocytosis and autoimmune hemolytic anemia.
