答案:【计分规则】: 1) It is recommended that all pregnant women who have not been diagnosed with PGDM or GDM be given 75gOGTT at the time of the first visit of 24-28 weeks of gestation and after 28 weeks of pregnancy.The diagnostic criteria of 75gOGTT: fasting, 1 hour and 2 hours after taking the blood sugar level are lower than 5.1mmol / L, 10.0mmol / L, 8.5mmol / L GDM can be diagnosed at any point when the blood glucose value reaches or exceeds the above criteria.2) In areas where pregnant women have high risk factors for GDM or lack of medical resources, it is recommended to check FPG first in 24-28 weeks. FPG ≥5.1mmol / L can be diagnosed as GDM without OGTT.
