Prediction of gestational diabetes at early pregnancy by using a clinical prediction model

The oral glucose tolerance test (OGTT) is recommended to rule out gestational diabetes mellitus (GDM) at 24+0 to 27+6 weeks of gestation. However, it is an ongoing debate how to reduce the number of invasive and expensive OGTT examinations in the clinical setting of pregnancy care. This study aims to assess the predictive accuracy of a previously defined risk estimation model (Göbl 2012) at a very early stage of pregnancy.
