In the United States, GDM is diagnosed by a 3 hour GTT when 2 or more values are above a designated cut off. But what happens when only one value is elevated? In this session, we will review the data regarding this clinical dilemma. We will also review if there is a clinical difference if the 1 elevated value is the fasting blood sugar or 1 of the 3 post glucose challenge. Data taken from SMFM briefings.
