Urine specific gravity test. Urine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine. After you provide a urine sample, it is tested right away. The health care provider uses a dipstick made with a color-sensitive pad. The color the dipstick changes to will tell the provider the specific gravity of your urine. The dipstick test gives only a rough result. For a more accurate result, your provider may send your urine sample to a lab. Your provider will ask you to temporarily stop taking any medicines that may affect the test results.
From Wikipedia: Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. As a ratio, it is dimensionless - there is no unit of measure. It does not matter what units you use for the mass of the substance and the reference, as long as they are the same units.
