Osmotic fragility test
{"Image DocumentName": "Osmotic fragility test", "Image ImageDescription": "The classic laboratory test for HS is the osmotic fragility test. In this test, erythrocytes are incubated in saline solutions with osmolality ranging from normal to pure water. Percent hemolysis is measured by spectrophotometry. Erythrocytes from patients with HS hemolyze at higher saline concentrations than normal cells. The difference is exaggerated by incubating the cells for 24 hours in the absence of glucose. It is important to remember that increased osmotic fragility is not specific for HS; any cause of spherocytosis results in increased osmotic fragility.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
