PNH Diagnostic Blood Test - Paroxysmal Nocturnal Hemoglobinuria (PNH) Test

It's not a single test, but a comprehensive laboratory diagnosis of paroxysmal nocturnal hemolysis, a rare acquired blood disorder. This is achieved through flow cytometry to detect the absence or deficiency of glycosylphosphatidylinositol (GPI)-stabilized proteins on the surface of red blood cells, white blood cells, and platelets. This deficiency makes red blood cells susceptible to hemolysis by the complement system.
