WebJun 1, 2002 · An osmotic fragility test primarily indicates the surface area-to-volume ratio (SAVR) of red blood cells (RBC). Osmotic fragility of RBCs is defined as the ease with which the cells burst in hypotonic solutions and is expressed in terms of the concentration of the saline solution in which the cells are hemolyzed ( Fig. 1 ). WebErythrocytes from blood stored in CPD-A2 were found to have a markedly increased osmotic fragility. A major portion of this increase was found to be due to accumulation of lactate, which is only slowly transported from within erythrocytes and which therefore exerts a strong osmotic effect in the usual osmotic fragility test.
