Urinary Calcium / Creatinine Ratio (24 Hrs)
Also Known As:
24 Hrs Calcium/Creat Ratio
About This Test
The Urinary Calcium/Creatinine Ratio (24 Hours) measures the relative excretion of calcium compared to creatinine in a 24-hour urine sample.
Because creatinine excretion is relatively constant, this ratio normalizes calcium output against urine concentration, helping assess calcium metabolism, bone turnover, and renal handling of calcium.
It is particularly useful for:
1. Detecting hypercalciuria (excess calcium excretion)
2. Evaluating renal calcium leak as a cause of kidney stones
3. Differentiating causes of hypercalcemia
4. Monitoring treatment of calcium metabolic disorders

Yes — a 24-hour urinary calcium/creatinine ratio (Ca/Cr ratio) test can detect early health problems, particularly those related to kidney function, calcium metabolism, and bone health.
TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
