A urine specific gravity test compares the density of urine and water. It can help doctors diagnose a variety of conditions, including dehydration.

Your urine specific gravity is generally considered normal in the ranges of 1.005 to 1.030. If you drink a lot of water, 1.001 may be normal. If you avoid drinking fluids, levels higher than 1.030 ...

commonly known as relative density, specific gravity is the ratio of density between a particular object and a standardized object such as water and air, acting as a basic comparison.

For example, the specific gravity of a urea solution of 2 gm. per 100 ml. is 1.0058, but that of a sodium chloride solution of 2 gm. per 100 ml. is 1.0146; to put it differently, an increase of ...
