What is the normal range for urine specific gravity in functioning kidneys?

The normal range for urine specific gravity in functioning kidneys is 1.002 to 1.030. This measurement indicates the concentration of solutes in the urine, which provides important insights into a person's hydration status and kidney function. A specific gravity within this range suggests that the kidneys are effectively concentrating urine and maintaining fluid balance in the body.

When specific gravity is below 1.002, it can be an indication of dilute urine, which could occur in situations of excessive hydration or certain renal pathologies. Values above 1.030 often imply concentrated urine, which may arise from dehydration, but could also indicate possible kidney conditions.

This range is essential for midwives and healthcare providers to understand as it helps them assess not only the hydration status of their patients but also to monitor kidney health. Evaluating urine specific gravity routinely allows for early intervention if abnormalities are found.
