title: Osmotic effects on neutrophil segmentation. An in vitro phenomenon.
abstract: Segementation of the nucleus is an important morphologic characteristic of mature neutrophils and is a useful parameter for their identification in various body fluids. From our studies, we have demonstrated that when mature neutrophils are placed in low specific gravity urine, cellular enlargement and a loss of nuclear segmentation occur, resulting in inaccurate identification. Both cytotechnologists and investigators involved in neutrophil research should be aware of the effects of tonicity on morphologic characteristics.
