口服葡萄糖筛查试验1小时静脉血浆血糖7.84 mmol/L已作为界值广泛应用于GDM的筛选,该界值用于筛选符合NDDG标准的糖尿病很有价值。Carpenter和Coustan提出了界值更低的100gOGTT标准,这个标准能筛选出程度较轻的糖代谢异常人群。近年来研究发现轻微糖代谢异常(包括糖筛查异常而OGTT正常和OGTT单项异常)者巨大胎儿及其他一些围产期并发症的发病率较正常人 Oral glucose screening test 1 hour venous plasma glucose 7.84 mmol / L has been widely used as a cutoff in the screening of GDM, which is valuable in screening NDDG-compliant diabetes. Carpenter and Coustan proposed a lower-bound 100gOGTT standard, which screened out to a lesser extent the population with impaired glucose metabolism. In recent years, studies have found that the incidence of macrosomia and other perinatal complications is slightly higher than that of normal people in mild glucose metabolism abnormalities (including normal glucose screening and normal OGTT and single OGTT abnormalities)
