Test Detail

Calcium/Creatinine Ratio, Urine spot

A calcium/creatinine ratio (Ca/Cr) in a spot urine sample helps evaluate calcium handling and metabolism, detecting abnormal calcium levels in the urine (hypercalciuria or hypocalciuria) and helping to diagnose related kidney or metabolic disorders. No special preparation is needed for the test, which involves providing a single urine sample to be analyzed for its calcium and creatinine content. An elevated ratio can signal conditions like hypercalciuria, while a low ratio might suggest hypocalciuria or other kidney issues.
