In 2010, the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) panel published consensus-based recommendations on the diagnosis and classification of hyperglycemia in pregnancy (1). Within that document, the recommendations regarding early pregnancy testing were designed to facilitate early detection and treatment of hyperglycemia (HbA1c ≥6.5% [48 mmol/mol], fasting venous plasma glucose ≥7.0 mmol/L, random plasma glucose ≥11.1 mmol/L with confirmation) that, outside pregnancy, would be classified as diabetes. The term “overt diabetes” was suggested to describe these women. Subsequently, the World Health Organization (WHO) adopted the IADPSG criteria with some modifications and promoted the use of the term “diabetes in pregnancy” (2) for this group.
Cognizant that milder degrees of hyperglycemia would also be detected by early pregnancy testing, the IADPSG also recommended that fasting …
