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.
1 Specific gravity of urine is a measure of the amount of solutes dissolved in urine as compared to water (1.000). 2  Specific Gravity measures the ability of the kidney to concentrate or dilute the urine and is directly proportional to urine osmolality (solute concentration). Specific Gravity measures the ability of the kidney to concentrate or dilute the urine and is directly proportional to urine osmolality (solute concentration). 2  Specific gravity between 1.002 and 1.035 on a random sample is normal IF kidney function is normal.
