Introduction: Urinary oxalate is recognized as an important biomarker for the diagnosis and monitoring of hyperoxaluria responsible for oxalocalcic lithiasis.
Objective: The main objective of our study, carried out in the Biochemistry and Analytical Chemistry Laboratory of the Pharmacy Department at the Université Mouloud Mammeri Tizi-Ouzou (UMMTO), is to develop and validate a method for the determination of urinary oxalate by reverse-phase HPLC, to be applied routinely in the biochemistry laboratory for the benefit of patients.
Method: Determination of urinary oxalate by reverse-phase HPLC (C18) after derivatization with ophenylenediamine. Validation according to SFSTP 2006 protocol V2 followed by stability study and establishment of internal quality controls.
Results: The method.. View more»
