Objective: To determine the adult reference intervals for the Siemens IgG subclass reagents. Methods: 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. Results: 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. Conclusions: 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.
