Which statement is accurate about urine specific gravity ranges?

Which statement is accurate about urine specific gravity ranges?

• A. Values above 1.030 indicate dilute urine.
• B. The normal range is 1.020-1.040.
• C. The normal range is 1.010-1.030.
• D. Values below 1.010 indicate concentrated urine.

Answer: (C)

Urine specific gravity shows how concentrated or dilute urine is, reflecting hydration status and the kidney’s ability to concentrate filtrate. A normal range is about 1.010 to 1.030, meaning urine is neither too dilute nor too concentrated under typical conditions. Values above 1.030 indicate concentrated urine, which can occur with dehydration, limited fluid intake, or increased ADH activity. Values below 1.010 indicate dilute urine, seen with overhydration, diuretic use, or impaired concentrating ability. Therefore, the statement that the normal range is 1.010-1.030 is accurate. The other options misstate the direction of concentration with higher or lower values or shift the normal range outside what is typically expected.
