A urine-specific gravity test compares the density of urine with the density of water. The test may help healthcare professionals identify dehydration, a kidney problem, or a condition like diabetes ...

Density and specific gravity instruments are meters used to determine the density and specific gravity of a mixture that may be solid, gas, or liquid. Specific gravity is the heaviness of a substance ...

The density of a substance is the ratio of its mass to its volume. It is always necessary to state the units of density because it may be expressed in a number of different mass and volume units.

THE clinical value of the urinary specific gravity is unchallenged by the thousands who routinely perform it as part of every urinalysis. The claim that it differentiates transudate from exudate in ...
