Abstract: Objective To establish reference interval of hemoglobin A1c(HbA1c) determined in healthy adults in northeast Si-chuan .Methods Venous blood was pumped from 494 individuals without previously diagnosed diabetes and other critical illness . The HbA1c level ,blood routine examination ,blood lipids ,fasting plasma glucose ,liver and kidney function were measured . Reference value of HbA1c was determined by 95% confidence interval through the mean of HbA1c .Results The HbA1c level took on normal distribution in 494 healthy individuals ,and the reference interval was 4 .482% -6 .012% .There was no statistical signifi-cance of HbA1c level between different genders(t= -0 .905 ,P= 0 .366) .The levels of HbA1c in 20 - < 35 years old people , 35- <65 years old people and ≥65 years old people were(5 .109 ± 0 .150)% ,(5 .224 ± 0 .122)% ,(5 .444 ± 0 .125)% ,and the differences were statistically significant among different age group(P<0 .05) .The HbA1c level and age were positively correlated (r=0 .338 ,P<0 .01) .Conclusion It is necessary to establish appropriate reference intervals of HbA1c for different laboratories or areas .
