MEDICAL PHYSIOLOGY

Detailed explanation-1: -URINE SPECIFIC GRAVITY (USG) measures the concentration of particles in urine and the density of urine compared with the density of water. Measuring USG is an easy and convenient way to gauge a patient’s hydration status as well as the functional ability of his kidneys.

Detailed explanation-2: -Urinary specific gravity (SG) is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with water density and provides information on the kidney’s ability to concentrate urine. A urinary specific gravity measurement is a routine part of urinalysis.
