Random Urinary Calcium/Creatinine Ratio as a Predictor of Dehydration in Hypercalcemic and Normocalcemic Patients
Background/Objectives: Dehydration is an under-recognized cause of hypercalcemia, and no validated bedside marker exists to distinguish it from other etiologies. We evaluated the urinary calcium-to-creatinine ratio (uCa/Cr) and the fractional excretion of calcium (FeCa) as predictors of dehydration across a spectrum of...
