[A modified method for the quantitative determination of urinary oxalic acid].
The present paper describes a modified method of the quantitative determination of oxalic acid in the urine which is based on the reduction of oxalic acid to glycolic acid and on the transformation with chromotropic acid to a colorimetrically well measurable complex of colours. The method ascertains a good reproducibility and is simply to be performed in every clinico-chemical laboratory.
