A study conducted by the University of Queensland has called for an “urgent need” to revisit the diagnostic criteria for gestational diabetes mellitus (GDM) diagnosis, encouraging the review of the one-step diagnosis recommended by the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) and practiced widely in Australia.
Australia currently undertakes the one-step diagnosis where a fasting patient undergoes a 75-gram, oral glucose tolerance test with measurements of blood glucose concentrations taken at the first hour and the second hour after administration of the glucose solution. The result would be considered abnormal if any one measurement, the fasting blood glucose concentration; taken prior to administration or the 1 hour, or 2-hour result is above a specified threshold.
