title: Are the WHO (1980) criteria for the 75 g oral glucose tolerance test appropriate for pregnant women?
abstract: OBJECTIVE
  To determine the normal response to a 75 g glucose challenge in the context of an oral glucose tolerance test in the third trimester of pregnancy.
  
  
  METHODS
  Prospective observational study.
  
  
  METHODS
  Antenatal clinic, Kandang Kerbau Hospital, Singapore.
  
  
  METHODS
  Sixty-four normal pregnant women with a low risk for diabetes.
  
  
  METHODS
  Glucose (75 g) challenge following an overnight fast after 28 weeks of gestation.
  
  
  METHODS
  Venous plasma glucose levels taken before and 2 h after the glucose challenge.
  
  
  RESULTS
  Upper limits of normality were found to be fasting glucose 4.9 mmol/l and 2 h glucose 9.2 mmol/l.
  
  
  CONCLUSIONS
  The WHO (1980) criteria should not be used in pregnancy.
