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

Spectrophotometry
Reference Interval
