Sulfate, Quantitative, 24-Hour Urine

The determination of sulfate in urine is of interest in sulfur metabolism studies. The urinary sulfate is mainly derived from sulfur-containing amino acids and is therefore determined by protein intake. This assay is also useful as part of a kidney stone risk profile.

This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
