What is Urine Specific Gravity?
Measures urine density or concentration compared to pure water. It reflects the kidney's ability to concentrate or dilute urine, indicating hydration status and renal concentrating ability. Low SG suggests dilute urine (e.g., overhydration, diabetes insipidus); high SG suggests concentrated urine (e.g., dehydration, glycosuria, proteinuria, SIADH).
