目的:探究并分析糖化血红蛋白(HbA1c)在糖尿病(DM)诊断中的价值。方法:选取自2011年6月-2013年6月来上虞区第二人民医院检查确诊或可疑有糖尿病的100例患者,将其作为观察组;另选取同期在该院进行体检的100例健康人,作为对照组。两组患者均行口服葡糖糖耐量试验(OGTT),对两组患者进行空腹血糖(FPG)以及HbA1c的测定,分别计算其两组空腹血葡萄糖和糖化血红蛋白检测的特异度和灵敏度情况,分析并比较FPG和HbA1c在DM诊断中的准确度。结果:观察组患者FPG、2hPG及HbA1c等三项指标检测水平明显高于对照组患者,组间比较具有统计学意义(P<0.05);HbA1c对DM诊断的灵敏度及特异度均高于FPG,且均与金标准所得诊断结果相似;不同临界值的HbA1c诊断检测的灵敏度和特异度明显高于临界值≥7.0mmol/L的FPG,P<0.05,讨论:HbA1c在糖尿病诊断中的特异度、灵敏度较FPG高,在DM早期诊断中具有显著的价值,可作为DM诊断的有效指标,值得在临床上广泛推广。
Objective: To investigate and analyze the value of glycosylated hemoglobin (HbA1c) in the diagnosis of diabetes mellitus (DM). Methods: A total of 100 patients with confirmed or suspicious diabetes from No.2 People’s Hospital of Shangyu District from June 2011 to June 2013 were selected as the observation group. Another 100 healthy subjects People, as a control group. The oral glucose tolerance test (OGTT) was performed in both groups. Fasting blood glucose (FPG) and HbA1c were measured in both groups. The specificity and sensitivity of fasting blood glucose and glycosylated hemoglobin were calculated and analyzed respectively And compare the accuracy of FPG and HbA1c in the diagnosis of DM. Results: The levels of FPG, 2hPG and HbA1c in observation group were significantly higher than those in control group (P <0.05). The sensitivity and specificity of HbA1c in DM diagnosis were higher than that in FPG, The sensitivity and specificity of the HbA1c diagnostic tests with different thresholds were significantly higher than those with the critical levels ≥7.0mmol / L, P <0.05. Discussion: The specificity of HbA1c in the diagnosis of diabetes, Sensitivity than FPG high in the early diagnosis of DM has a significant value, can be used as a valid indicator of DM, it is worth widely disseminated in the clinic.
