Clinical Significance
Used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease, and tetany (intermittent muscular contractions or spasms).
The main significance in determining urinary calcium lies in the differentiation between hypercalciuria and hypocalciuria and the differential diagnosis of nephrolithiasis.
