Significance of negative free water clearance
WebIn the physiology of the kidney, free water clearance (CH2O) is the volume of blood plasma that is cleared of solute-free water per unit time. An example of its use is in the determination of an individual's state of hydration. Conceptually, free water clearance should be thought of relative to the production of , which would be equal to the osmolarity of the … WebThe urine is hyposmotic, and free-water clearance is positive. When ADH levels are high, all of the free water generated in the thick ascending limb and the early distal tubule is reabsorbed by the late distal tubule and collecting duct. The urine is hyperosmotic, and free-water clearance is negative. Measurement of CH2O. Free-water clearance ...
