A urine concentration test measures the ability of the kidneys to conserve or excrete water.
A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that's too concentrated could mean that your kidneys aren't functioning properly or that you aren't drinking enough water.
Urine is concentrated in the final stages of its production: water is absorbed, in excess of solute, from the collecting ducts and into the vasculature of the medulla, thus increasing the osmolality of the collecting duct fluid and thus the osmolality of the urine that emerges from the collecting ducts.
