Urine Osmolality

A Urine Osmolality Test is used to measure the ability of the kidneys to concentrate urine. This is a good indicator of the proper functioning of the kidneys. Urine Osmolality can also be used to identify electrolyte and water imbalance.

Often, the serum and urine osmolality tests are run together. When done together, the two tests are most informative about the body’s ability to properly maintain water and electrolyte balance, and may also indicate dehydration or over-hydration.
