We describe a new sensitive and specific method for determination o f oxalate in human serum. By using the chemiluminescence decay of monoperoxyoxalic acid very low concentrations o f oxalate (200 nmol/L) can be determined. The mean serum oxalate level in apparently healthy controls was 14.5 f 8.5 p

A procedure for the estimation of oxalic acid in urine based upon its quantitative reaction with 1,2-diaminobenzene and subsequent estimation of the quinoxaline by reverse-phase highperformance liquid chromatography has been developed. The method has given good reproducibility; recovery of added oxa
An isotope dilution procedure for oxalate based upon [1,2-'T,]oxalic acid is described. For routine determinations of urinary concentration, a known quantity of sodium [1,2-1 'Tloxalate is admixed with the sample, total oxalate precipitated as the calcium salt, and converted by BF, catalysis to di-n
