IGT is defined on the basis of an abnormal oral glucose tolerance test (OGTT). Persons without diabetes but with an OGTT 2-hour value of 140-199 mg/dl are considered to have IGT. Recent national and international randomized controlled trials have shown that diabetes can be delayed or prevented among persons with IGT.

2024年7月18日 · Discover the Oral Glucose Tolerance Test (OGTT), used to diagnose diabetes and assess glucose metabolism over time, with detailed procedure and interpretation.

Fasting plasma glucose (measured before the OGTT begins) should be below 5.6 mmol/L (100 mg/dL). Fasting levels between 5.6 and 6.9 mmol/L (100 and 125 mg/dL) indicate prediabetes ("impaired fasting glucose"), and fasting levels repeatedly at or above 7.0 mmol/L (>126 mg/dL) are diagnostic of diabetes.

Definition: An OGTT is commonly used in the U.S. The OGTT assesses how an individual uses glucose over time by measuring the participant’s plasma glucose level before and at defined intervals for 2 hours after drinking a solution containing 75 grams (or 1.75 g/kg) of glucose.
