What is the normal range for urine specific gravity?

What is the normal range for urine specific gravity?

• A. 1.005 to 1.030
• B. 0.985 to 1.005
• C. 1.040 to 1.050
• D. 1.000 to 1.010

Answer: (B)

Urine specific gravity shows how concentrated the urine is, reflecting the kidney’s ability to dilute or concentrate it in response to hydration and antidiuretic hormone. The normal range is about 1.005 to 1.030. Values at the low end indicate dilute urine (well-hydrated or diuresis), while values at the high end indicate concentrated urine (dehydration or increased ADH effect). Lab reference ranges can vary slightly, but 1.005–1.030 is the standard benchmark.
