The Hypertonic saline solution lyses the cells within the tissues by the mechanism of osmotic shock and dissociation of DNA from proteins [18].
In a previous study, hemolysis generated by the osmotic shock method led to elevated measured plasma ammonia concentration, whereas hemolysis generated by the shearing method had little to no effect on plasma ammonia measurement.
