Mechanical fragility (MF) refers to the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to mechanical stress, such as (typically) some kind of shear stress. Yet unlike with osmotic fragility, no single approach for testing mechanical fragility has yet gained sufficient acceptance to enable standardization. This has led to some insurance companies not currently covering the test. WebDetermination of hemoglobin and RBC osmotic fragility. Hemoglobin and RBC osmotic fragility were determined by the method of Dacie et al. (13). For practical purposes, mean corpuscular fragility was employed for data analysis of RBC osmotic fragility defined as the NaCl concentration (g/l) causing 50% RBC lysis (13). RBC incubation tests
