Determination of Urinary Creatine

[摘要] A method of separation of creatine using ion-exchange chromatography is described. This method is suitable for serial determinations of urinary creatine despite a small contribution by creatinine and guanidino compounds to the color value of the α-naphthol and diacetyl reaction. The creatine coefficients of four patients, determined in duplicates, before and after the induction of creatinuria by X-irradiation are presented to illustrate the applicability of the method described.
