Body fluid specific gravity is a laboratory test that measures how dense a fluid sample from your body is compared to water, which helps doctors understand what substances are present in that fluid. You might need this test if your doctor is investigating kidney problems, dehydration, or other conditions affecting how your body processes fluids, or if they're checking a sample from an unusual body fluid collection. The test itself is simple—a small sample of your urine, cerebrospinal fluid, or other body fluid is collected and analyzed using specialized equipment, with results typically available within a day or two.
