There are two main methods for diagnosing GDM. The One-step approach: 75-g Oral glucose tolerance test; and the Two-step approach with a 50-g (non-fasting) screen, followed by a 100-g OGTT for those who screen positive. Both methods can accurately diagnose GDM, but one-step strategy has been adopted internationally and has improved pregnancy outcomes with cost savings and may be the preferred method of diagnosing GDM.
