To determine the adult reference intervals for the Siemens IgG subclass reagents.
636 blood samples of healthy adults were analyzed to determine the level of IgG subclass using the reagents of Siemens immunonephelometric assay with molecular biology kits.
IgGSc reference intervals were as follows: IgG1 4.45-9.76 g/L, IgG2 2.07-8.57 g/L, IgG3 0.08-0.80 g/L and IgG4 0.05-1.54 g/L. There was an excellent correlation between the total IgG and the sum of the IgG subclasses. No significant gender and age differences were observed.
Our data provide the missing reference intervals and enable the use of the nephelometric IgG subclass reagents in Chinese. The study can offer reference on clinic diagnose.
确定西门子IgG亚类试剂的成人参考区间。
采用西门子免疫比浊法分子生物学试剂盒试剂，对636例健康成年人血液样本进行分析，以确定IgG亚类水平。
IgG亚类参考区间如下：IgG1 4.45 - 9.76 g/L，IgG2 2.07 - 8.57 g/L，IgG3 0.08 - 0.80 g/L，IgG4 0.05 - 1.54 g/L。总IgG与IgG亚类总和之间存在良好的相关性。未观察到显著的性别和年龄差异。
我们的数据提供了缺失的参考区间，并使免疫比浊法IgG亚类试剂能够在中国使用。该研究可为临床诊断提供参考。
