Hematology Test
 

Sugar Water Test Screen/ PNH Test Screen/ Sucrose Hemolysis Test
Lab Test
Test Sugar Water Test Screen/ PNH Test Screen/ Sucrose Hemolysis Test
Indication The screening test for suspected paroxysmal nocturnal hemoglobinuria (PNH). Confirm the test with Ham Test.
Normal Range If no hemolysis is present, the patient probably does not have PNH provided multiple recent transfusions have not reduced the proportion of abnormal cells.
Test Results If the sugar water test is positive, a subsequent Ham test is strongly recommended. A negative sugar water test rules out PNH in most instances, provided the proportion of patient cells has not been reduced by previous transfusion. It has been demonstrated that the most complement sensitive cells in PNH are younger RBCs and reticulocytes. Increased sensitivity can be obtained for the assays by separating young RBCs from old by centrifugation.
Related Tests Erythrocyte complement fixation Test,Ham Test
