目的　探讨在体检人群中进行餐后2h指血血糖检测筛查糖尿病的临床意义。方法　对2 081例体检人群行100g标准粉馒头餐餐后2h指血血糖( 2hPBG) 检查, 2hPBG≥6. 5mmol/L者, 进一步行75g口服葡萄糖耐量(OGTT) 检查。结果　经100g馒头餐后2hPBG筛查, 2hPBG≥6 5mmol/L者609例, 其中68例进行了75gOGTT检查, 确诊糖尿病16例, 葡萄糖调节受损者36例。结论　在健康体检中加测2hPBG有助于早期筛查出糖尿病, 减少漏诊。 Objective To investigate the clinical significance of detecting blood sugar in blood test in patients after 2 hours of meal examination. Methods The blood glucose (2hPBG) was measured at 2 h after meal check of 2 081 healthy volunteers and 2g PBG≥6.5mmol / L at 2h after meal inspection. The oral glucose tolerance (OGTT) of 75g was further tested. Results 100g steamed bread 2hPBG after screening, 2hPBG≥6 5mmol / L were 609 cases, of which 68 cases were 75gOGTT examination, diagnosed with diabetes in 16 cases, impaired glucose regulation in 36 cases. Conclusion Adding 2-hPBG in healthy physical examination can help early screening out diabetes and reduce missed diagnosis.
