Low urine osmolality indicates
WebThe U Osm is equal to the number of excreted osmoles divided by the urine volume. Therefore, during a water diuresis, the U Osm reflects the osmole excretion rate and the volume of filtrate delivered to the distal nephron (which largely determines the urine volume in this setting). For example, if the rate of excretion of osmoles is 800 mosmol ... Web24 jan. 2024 · Osmolality indicates the concentration of all the particles dissolved in body fluid.
