[A micromethod for determination of serum zinc and copper concentration in infants aged 1-3 months in Chengdu].
A micromethod for the measurement of serum zinc and copper concentration of peripheral blood by wave-oscillopolarography is introduced in this article. The method is superior to the commonly used flame atomic absorption spectrophotometry (AAS) in its simplicity in sampling and operating and in its inexpensiveness. Yet the results are identical with those obtained by ASS, the method is good enough to replace ASS in clinical work, especially in the field of pediatrics. Serum zinc and copper concentrations in 243 infants aged 1-3 months in Chengdu were detected by this method. The data were found to be slowly distributed without age and sex differences. For the infants of 1-3 months in Chengdu, the reference values of serum zinc and copper concentration are 6.69-25.46 mumol/L and 8.70-28.07 mumol/L respectively.
