Background. Hyperoxaluria is a major risk factor for kidney stone formation. Although urinary oxalate measurement is part of all basic stone risk assessment, there is no standardized method for this measurement. Methods. Urine samples from 24-h urine

We report that conditions employed in the pre-treatment of the urine are crucial to the correct estimation of oxalate. Interference of ascorbic acid, a common urinary constituent, has been noted in a number of different methods. After systematic inve
