Oxalate determination in urine by oxsalate oxidase on the solid carrier

A biosensor for determination of oxalate concentration was obtained by immobilisation of oxalate oxidase on the catalysed oxalic acid oxidation with simultaneous production of hydrogen peroxide. Oxalate oxidase catalysed oxalic acid oxidation with simultaneous production of hydrogen peroxide.Hydrogen peroxide concentration was measured amperometrically and the current produced was proportional to oxalic acid. Biosensor linearity was measured in aqueous solutions of oxalic acid. Sensitivity and specificity of the biosensor were examined with gas chromatography as reference. The reference values of urine oxalate were expressed according to the urine creatinine concentration.
