Abstract:
Objective To study the values of glycosylated hemoglobin in screening for patients with prediabetic state in Guang-zhou region .Methods 525 Guangzhou people who had accepted health examination were enrolled and were subjected to oral glucose tolerance test(OGTT) .BIO-RAD D-10 automatic glycosylated hemoglobin analyzer was employed to detect their glycosylated he-moglobin A1c(GHbA1c) .OGTT results were served as diagnostic criteria ,Receiver operator characteristic (ROC) curve analysis was performed to obtain the optimal threshold of GHbA1c in diagnosing impaired glucose regulation (IGR) .Results The optimal threshold of GHbA1c in diagnosing IGR was 5 .95% .The sensitivities of GHbA1c≥5 .95% and GHbA1c≥5 .7% in diagnosing IGR were 53 .3% and 84 .8% ,respectively ,while their specificities were 72 .8% and 31 .0% ,respectively .The difference of sensitivity between GHbA1c≥5 .95% combined with FPG≥5 .6 mmol/L and GHbA1c≥5 .7% alone in diagnosing IGR showed no statistical significance(P= 0 .406) ,while the specificity increased obviously (P= 0 .000) .Conclusion The criteria of GHbA1c≥5 .7% can be used for prediabetic state screening but not for diagnosis .GHbA1c≥5 .95% combined with FPG≥5 .6 mmol/L can be used effectively for prediabetic state screening in Guangzhou people .
