Gestational-diabetes-mellitus - Diagnosis

Although the risk of GDM is higher in certain groups of women, it can happen to any woman in her pregnancy. In Singapore, all pregnant women will be offered screening for GDM with an oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy.

If you have had GDM before, having glucose in the urine, or symptoms suggestive of diabetes, the OGTT will be performed earlier in pregnancy and repeated again at 24 – 28 weeks if the first test was normal. 

Detection of GDM is important so that appropriate treatment can be given to reduce the risks to the pregnancy.

An OGTT to diagnose GDM requires:
  • Fasting overnight (not eating or drinking anything besides water)
  • Blood test for glucose in the morning, followed by a 75g glucose drink
  • Repeat blood test for glucose at 1 hour and 2 hours after the glucose drink
