Calcium, Urine

Diagnostic Use

Calcium is an electrolyte which plays an important role in many physiological processes throughout the body. In normal health, almost all of the filtered calcium is reabsorbed in the post-glomerular nephron.

Urinary calcium excretion exhibits diurnal variation, largely reflecting dietary intake. As such, a 24 hour collection is the best way to assess urine calcium status.
