Early Screening for Gestational Diabetes Mellitus
Early Screening for Gestational Diabetes Mellitus
The working hypothesis of this proposal is that screening for gestational diabetes mellitus
 as early as the 1st trimester is efficient for detecting the forthcoming presence or absence
 of gestational diabetes mellitus. The investigators long-term goal is the prevention of
 gestational diabetes mellitus onset i.e. the prevention of progression to gestational
 diabetes mellitus, in order to enable delivery of appropriate counselling, diagnostics and
 treatment for pregnant women, as well as to improve pregnancy outcomes. Therefore, robust 1st
 trimester screening criteria is needed.

 The overall objective of this proposal is to determine an accurate and valid 1st trimester 1h
 post 50g oral glucose challenge test plasma glucose cut-off value that is predictive of
 gestational diabetes mellitus onset.
