Brief Summary:

Gestational diabetes mellitus (GDM) is an asymptomatic disease. Diagnosis is based on a oral glucose tolerance test (OGTT) requiring pregnant women to absorb 75g of glucose while fasting since midnight and to stay sober for another two hours. These OGTTs are poorly tolerated by pregnant women. As many OGTT are false positive according to self-monitoring blood glucose (SMBG), the investigators need now to determine the percentage of OGTT results that are false negative.

The comparison of the two tests (OGTT and SMBG) in the same patient with normal results of OGTT will determine the exact percentage of false negative OGTT results.

The opinion of women will also be taken into account. In the everyday clinic, many report that they prefer SMBG to OGTT because they do not have to be fasting, to drink non palatable drink and to attend a 2-hour visit in their schedule. However, no opinion study has yet been performed, the investigators will investigate formally what women think using a questionnaire.

Intervention Details:
  • Procedure: Diagnosis
    Oral glucose tolerance test and self-monitoring blood glucose

Primary Outcome Measures :
  1. proportion of OGTTs falsely negative [ Time Frame: Will be evaluated when participants finished SMBG i.e. 7 days after the OGTT ]

Secondary Outcome Measures :
  1. preference of participants regarding the two tests (OGTT vs. SMBG) [ Time Frame: Will be evaluated when participants finished SMBG i.e. 7 days after the OGTT ]
    Evaluated by questionnaire
