Rbc fragility test
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. WebIn this month’s “Hot Topic,” James Hoyer, M.D., discusses the importance of using a control tube during osmotic fragility testing.
