Free water clearance

Summary of Free water clearance
Free water is defined as distilled water that is free of solutes. In the nephron of the kidney, free water is generated in the diluting segments, which are the thick ascending limb and the early distal tubule. These sections are impermeable to water, thus solute is reabsorbed without water. Measurement of free water clearance provides a method for assessing the function of the kidney.
