摘要
介绍利用国产仪器,采取指微量血液测定血清锌的方法,建立正常值.方法 采用阳极溶出分析技术.结果 测量范围0.37μmol/L~33.6μmol/L,批内变异系数3.1%,批间4.3%,平均回收率98.7%,调查569名健康小儿正常参考值((?)±s)为14.18μmol/并与静脉血配对比较h=0.986.结论 本法简单快速、灵敏精确、经济实用,尤适于大批普查,值得推广.
To introduce a method for analysing serum Zn by Chineses apparatuses and its normal datums. Specimen was minimal blood from finger extremity. Methods Positive pole hemdysitic analytical technique. Results 569 healtly children were investigated. Normal datums (x±s) was 14. 18μmol/L±2. 44 μmol/L. Assay range was 0. 37μmol/L - 33. 6 μmol/L. Within groups CV value was 3. 1 % and among groups CV value was 4. 3%. Mean recovery rate was 98. 7%. Correlation coefficient with specimen of vein blood was r=0. 968. Conclusions The assay is suitable for wide investigation and worth being popularized, which is simple、rapid、sensitive、accurate、 useful and practial.
