Diagnostic and therapeutical value of FPG,GA,HbA1c and GA/HbA1c ratio in T1 DM/T2 DM / 中国免疫学杂志

ABSTRACT

Objective:To investigate the diagnostic and terapeutical value of FPG,GA,HbA1c and GA/HbA1c ratio in T1DM/T2DM.Methods:The study was made by case-control method.In our study,30 healthy subjects were selected from health physical ex-amination as control group while 160 diabetics were selected as case group,in which there are 76 TIDM and 84 T2DM.Analyzing the difference of relevance of FPG,GA and HbA1c,the difference of GA/HbA1c and threshold of the case and the control,and this analysis was also used between the T1DM and the T2DM.The data was managed by independent-sample t test,ROCK and Pearson correlation test of SPSS.Results:The results of FPG,GA ,HbA1c and GA/HbA1c ratio of T1DM and T2DM were significantly higher than those in the control group(P0.05),and weakly negative correlative with HbA1c(P>0.05);in T2DM group,there were positive correlation among FPG,GA and HbA1c(PFPG/GA>FPG/HbA1c;analyzing the ROC of measures in T1DM group,the sensitivity and specificity were re-spectively 86.8% and 100% for diagnosing DM when FPG threshold was set on 5.86 mmol/L ( AUC=0.922 ) ( P0.05).Conclusion:FPG,GA, HbA1c and GA/HbA1c ratio are of high value in monitoring of blood glucose, diagnosis and typing in T1DM and T2DM.There are missed diagnosis when we diagnose T1DM and T2DM by the upper limit of reagent instruestion of FPG,GA,HbA1c.It is more important for a person with T1DM to monitor FPG than others.
