su·crose he·mol·y·sis test

isotonic sucrose promotes binding of complement to red blood cells; in paroxysmal nocturnal hemoglobinuria a proportion of the cells is sensitive to complement-mediated lysis, and hemolysis ensues.

sucrose hemolysis test

A screening test for paroxysmal nocturnal haemoglobinuria (PNH), which is based on binding of complement to red cell membranes. In the test, red cells from a patient are incubated in isotonic saline mixed with sucrose in barbital. Lysis of > 10% of tested red cells is typical of PNH.
