Evaluation and Validation of New Biomarkers by Mass Spectrometry (DG7)

May 2, 2018 updated by: Jean-Luc Ardilouze, Université de Sherbrooke

A New Approach by Mass Spectrometry for Evaluation and Validation of New Biomarkers of Fetus and Mother

The investigators will perform biochemical and metabolic evaluations on cord blood, venous blood of the mother and urine of the foetus and mother using time-of-flight and tandem mass spectrometry. The investigators could evaluate, dose and validate gestational diabetes mellitus biomarkers of the fetus and mother.
