Test Details
Methodology
Spectrophotometry
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
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.
