WebOsmotic fragility was measured by traditional method. For performing the fragility test of RBC, a series of hypotonic solution of NaCl were made with different strength in twelve test tubes, numbered serially (no-1 was 0.9% of NaCl to no -12 was 00%) and kept in the test tube rack. One drop of anticoagulant mixed blood was added WebWith the technique of Parpart et al (1947), the normal range for osmotic fragility of red blood cells had been estimated to include 5%--45% haemolysis at a salt concentration corresponding to 4.5 g NaCl/l (Dacie 1954). This estimate may be questioned, however. Thus, nearly 20% of the data obtained f …
