Andrea, Oliver, and Jerome filled a 28.50-gram pycnometer. When filled full of water, it weighs 53.50 grams, and when filled with their urine sample, it weighs 54.64 grams (Andrea), 53.57 grams (Oliver), and 53.91 grams (Jerome), respectively. EVALUATE THE STATEMENT. (I) Andrea’s urine sample has a specific gravity of 1.0046, while (II) Oliver’s is 1.0028. I is true, II is false. I is false, II is true. Both I and II are true. Both I and II are false.
Urine-specific gravity is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with the water density and provides information on the kidney’s ability to concentrate urine. A urinary-specific gravity measurement is a routine of urinalysis. The normal reference range is 1.005 to 1.030.
