Urine Calcium/Creatinine Ratio Test

The Urine Calcium/Creatinine Ratio test measures the levels of calcium and creatinine in the urine to evaluate calcium metabolism, kidney function, and the risk of kidney stone formation. This test helps in diagnosing conditions related to abnormal calcium excretion, such as hypercalciuria (high urinary calcium levels) or hypocalciuria (low urinary calcium levels).

Why is the Urine Calcium/Creatinine Ratio Test Important?

• High calcium/creatinine ratio may indicate hyperparathyroidism, vitamin D toxicity, excessive calcium intake, or kidney stones.
• Low calcium/creatinine ratio may be seen in vitamin D deficiency, malabsorption disorders, or certain kidney diseases.
• This test is particularly useful in assessing children with suspected metabolic bone diseases and individuals with a history of kidney stones.
