It is recognized that the nonspherocytic congenital hemolytic anemias are composed of a variety of syndromes with similar red blood cell (RBC) morphology. In 1954, the autohemolysis test was described,1 and helped to categorize the nonspherocytic congenital hemolytic anemias. The precise method of performing the autohemolysis test is described elsewhere.2 Briefly, the patient's blood is collected in a sterile manner and defibrinated. Two milliliters of the sterile defibrinated blood is added to sterile screw-capped vials. Sterility is important, for bacterial contamination will hemolyze RBC.
