U.S., April 9 -- ClinicalTrials.gov registry received information related to the study (NCT06916559) titled 'Comparison of Different Methods for Measuring Urinary Oxalate and Citrate: An Observational Study' on April 01.
Brief Summary: This observational study aims to compare three different laboratory methods for measuring urine oxalate and citrate concentrations. The primary objective is to evaluate whether an improved High-Performance Liquid Chromatography (HPLC) method-using a novel derivatization reagent-can achieve similar accuracy to the gold standard Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) while offering advantages in cost, speed, and ease of use in routine clinical settings.
The study will involve the collection...
