Isotachophoretic Determination of Oxalate in Unprocessed Urine
Measurement of urinary oxalate is important in the elucidation of the mechanisms of renal stone formation. Methods recently described for measuring oxalate depend mainly on colorimetry or enzymatic destruction utilizing the specific enzyme oxalate decarboxylase (E.C. 220.127.116.11). All of the colorimetric methods1,2,3 and most of the decarboxylase methods4,5,6 require treatment of urine prior to measurement. This introduces the possibility of incomplete recovery and conversion of other substances into oxalate7. The pre- treatment procedures described involve precipitation with calcium2, pre-treatment with anion-exchange columns2, or precipitation of calcium oxalate with 14C-oxalate4.
