A method for the determination of copper in hepatolenticular degeneration patient's serum and urine by flame atomic absorption spectrometry was developed, and the meaning of clinic diagnosis and therapy for copper lever of hepatolenticular degeneration patient in serum and urine was discussed. The detection limit and linear range for copper are 7.3 x 10(-3) micrograms.mL-1 and 0.008-5 micrograms.mL-1 respectively. The relative standard deviation is less than 1.4% and the recovery is 94%-104%. The experimental results show that serum copper and urine copper contents are really important reference index for diagnosing the disease, with guiding significance for timely monitoring and controlling serum copper and urine copper excretion, especially in therapy, although they do not have separate diagnosing significance for hepatolenticular degeneration disease and have to be combined with clinic symptoms and other biochemical indexes to make a comprehensive diagnosis. This method has been applied to clinic diagnosis and therapy with satisfactory results.
