Random Urinary Calcium/Creatinine Ratio as a Predictor of Dehydration in Hypercalcemic and Normocalcemic Patients

Paper C Peer reviewed Observational

Key takeaways

This study tested whether one urine sample, comparing calcium against creatinine, can flag dehydration. Creatinine is a waste product used to judge how concentrated the urine is. It is an observational study, so it shows a link, not proof of cause. Spotting dehydration early matters because it can injure the kidneys.
