Osmotic Fragility Test Of Erythrocyte
Osmotic Fragility Test Of Erythrocyte INTRODUCTION Red blood cell membrane restricts the solutes and allows only water to pass through them(osmosis). if the cells are placed in hypertonic solution sodium chloride (solution concentrated than normal saline e.g. 2%, (W/V), they shrink due to exosmosis. The red cells absorb water when kept in hypertonic solution (solution
