Urine Specific Gravity
Urine specific gravity measures how concentrated urine is compared with pure water and reflects the kidney's ability to concentrate or dilute urine. Low values suggest overhydration or impaired concentrating ability in diabetes insipidus, while high values indicate dehydration, glycosuria, or proteinuria. It is interpreted together with clinical hydration status and other urinalysis findings.

What is Urine Specific Gravity?
Urine specific gravity measures how concentrated urine is compared with pure water and reflects the kidney's ability to concentrate or dilute urine. Low values suggest overhydration or impaired concentrating ability in diabetes insipidus, while high values indicate dehydration, glycosuria, or proteinuria. It is interpreted together with clinical hydration status and other urinalysis findings.
Why It Matters
Measures urine concentration, reflecting kidney's ability to concentrate or dilute urine. Low values suggest overhydration or kidney concentrating defect;high values indicate dehydration or conditions causing excess solutes.
