目的探讨HbA_1c作为糖尿病诊断标准的临床应用价值。方法对43例个体行75gOGTT和HbA_1c检测。结果 HbA_1c≥6.0%和≥6.5%分别作为诊断糖调节异常和糖尿病的标准,其灵敏度分别为70.59%和50.00%,特异度为88.89%和77.78%。结论以HbA_1c≥6.0%作为糖调节异常的诊断标准具有较好的临床应用价值,但以HbA_1c≥6.5%作为糖尿病诊断标准的应用价值并不满意。 Objective To investigate the clinical value of HbA_1c as a diagnostic criterion for diabetes mellitus. Methods 43 cases of individual line 75gOGTT and HbA_1c detection. Results HbA_1c≥6.0% and≥6.5% were used as the standard for diagnosis of abnormal glucose regulation and diabetes mellitus. The sensitivity was 70.59% and 50.00% respectively, and the specificity was 88.89% and 77.78% respectively. Conclusion The diagnostic value of HbA_1c≥6.0% as a diagnostic criteria for glucose regulation has a good clinical value, but the value of HbA_1c≥6.5% as a diagnostic criteria for diabetes is not satisfied.
