      Evaluating the diluting and concentrating capacity of the kidney can be accomplished with three basic laboratory tests, urine and plasma osmolalities, and circulating levels of antidiuretic hormone. When used with simple techniques to stimulate dilution and concentration, these tests will provide critical clinical information in patients with defects in either dilution or concentration of the urine.
