A method for determination of oxalic acid in urine, described by Zarembski & Hodgkinson in 1965, was discussed and its reproducibility, recovery and relation to vitamin C were sutdied. A part of vitamin C in sample is determined as oxalic acid by this method. The good relationship between this method and Yarbro & Simpson's method (1956), r=0.862, was found.
