Which statement about urine specific gravity 1.035 is true?

• A. It is above the normal reference range.
• B. It is within the normal reference range.
• C. It indicates fully hydrated status.
• D. It indicates kidney failure.

Answer: (A)

Urine specific gravity shows how concentrated the urine is, reflecting how well the kidneys are concentrating urine and how hydrated a person is. A normal range is roughly 1.005 to 1.030. A value of 1.035 is higher than that upper limit, so the urine is concentrated. This points to dehydration or conditions that promote water reabsorption (like increased ADH activity). It’s not a sign of being fully hydrated—in fact, it suggests the opposite. It also doesn’t by itself indicate kidney failure; in kidney failure the kidneys often lose the ability to concentrate urine, which can produce a low or normal isosthenic value rather than a high one.
