ABSTRACT
The purpose of the study is to establish a colorimetric method of HEC toxin hemolysis test for diagnosis of paroxysmal nocturnal hemoglobinuria (PNH). RBCs from normal persons and patients with PNH and non-PNH anemia were treated with HEC toxin secreted by Aeromonas hydrophila J-1 strain and the absorbance at 630 nm was measured to quantitate the extent of hemolysis. The results demonstrated that the RBCs from PNH patients showed resistance to the toxin hemolysis, which was in accord with the percentages of CD59(-) cells, while the RBCs from normal persons and non-PNH anemic patients were nearly totally lysed. It is concluded that the method can be considered as a simple, specific and reliable method for the diagnosis of PNH.
