[QUOTE="Lamont D, post: 1992610, member: 85785"] For type two or prediabetes, an OGTT is standard at 75g of pure glucose, the fasting or none fasting glucose tolerance test is dependent on what they are looking for. The tests are not as thorough as they once were. Indeed, I have heard that only pre glucose drink and two hour readings are only taken in some such tests, not the usual, reading every fifteen or thirty minutes readings. And no c-peptide or GAD test either. A true diagnosis for an extended OGTT, requires fasting reading, readings every fifteen minutes, for first hour, then half hourly, till up to five hours after, unless the readings go too low. As well as a venous blood sample taken, pre glucose, an hour and when the test is finished. The reason for the extended test is to discover what happens after the two hours. Because some blood glucose levels do not drop into the patients hba1c levels until after the two hour mark. A c-peptide and GAD are necessary as a diagnostic tool to measure insulin levels. Some type two have symptoms and hypoglycaemic episodes similar to Reactive Hypoglycaemia! Some metabolic syndrome conditions, within the diabetes or endocrine need longer than the standard two hour glucose tolerance test! [/QUOTE]
