What are the diagnostic criteria for gestational diabetes? A glucose level of 190 mg/dL, or 10.6 mmol/L, is indicative of gestational diabetes. On a glucose challenge test, a blood sugar level below 140 mg/dL (7.8 mmol/L) is often regarded within the normal range, however this may vary by clinic or laboratory.
What is the diagnostic gold standard for gestational diabetes? Gestational diabetes mellitus (GDM) is connected with maternal and fetal diabetic problems throughout pregnancy. The typical Gold Standard (GS) for the diagnosis of GDM is a 75 g oral glucose tolerance test (OGTT) performed between 24 and 28 weeks of pregnancy, which appears a bit late for appropriate management.
WHO suggested OGTT? DIPSI advises a non-fasting Oral Glucose Tolerance Test (OGTT) with 75g of glucose and a cut-off of 140 mg/dl after 2 hours, however WHO (1999) suggests a fasting OGTT with 75g of glucose and a cut-off of 140 mg/dl after 2 hours.
