Objective To observe the interference of glucose-6-phosphate dehydrogenase (G6PD) deficiency on glycated hemoglobin (HbA1c) detected by three measurement systems.Methods A total of 286 cases of blood and serum samples were collected at Zhongshan Hospital of Sun Yat-Sun University from August 2012 to April 2016.The blood samples were divided into healthy control group (122 cases),diabetes group (82 cases),glucose-6-phosphate dehydrogenase deficiency group (61 cases) and diabetes with G6PD deficiency group (21 cases).The levels of HbA1 c were detected by three measurement systems,including Primus Ultra2,Variant lⅡ Turbo 2.0 and Modular P.The results of HbA1c were converted into the estimated average blood glucose concentration (eAG).The values of A eAG-FPG in different groups were calculated and statistical analysis was performed for evaluation of the differences from the three measurement systems.Results The HbA1c results measured by the three systems and AeAG-FPG values in G6PD deficiency group were all lower than healthy control group(all P <0.05).The measured results were similar in both diabetes group and diabetes with G6PD deficiency group.Conclusion G6PD deficiency may cause false H-bA1c results detected by three measurement systems.In the case of HbA1c for evaluating blood glucose control,the interference of G6PD deficiency should be noticed.

HbA1c measures chronic glycemia and is widely used to judge the adequacy of diabetic treatment and adjust therapy.According to ADAG study,the relationship between HbA1c and the calculated AG can be expressed as the linear regression:eAG(mg/dL)=28.7?HbA1c-46.7.ADA has adopted this equation on its website.In the same unit of measurement as used in self-monitoring blood glucose,eAG would facilitate the doctors to communicate with patients in the daily glucose control.
