Impaired glucose tolerance (IGT): A person is said to have impaired glucose tolerance when the fasting plasma glucose is less than 126 mg/dl and the two hour glucose level is between 140 and 199 mg/dl. This is sometimes referred to as prediabetes because people with IGT have a higher risk of developing diabetes.
Please note that for a glucose tolerance test, you will need to stay in the laboratory for one or two hours (depending on the specific test your doctor ordered), so you may want to bring a book, game or handwork to do while you wait. Here are answers to some commonly asked questions about fasting.
