[A photometric determination of copper in urine (author's transl)].
A photometric determination for urinary copper excretion in 24-hour urine is described. 6-methylpicolonic acid-thioamide as a 3.3 mmol/l solution in methanol is used as the reagent. It is highly specific and sensitive for copper-I ions, and stable. The method can be used for qualitative screening for Morbus Wilson, and for monitoring the urinary copper excretion fo Morbus Wilson patients under penicillamine therapy.
