Tests for prediabetes and diabetes Fasting plasma Oral glucose Hemoglobin A1c glucose tolerance test (HbA1c) * (OGTT) * Normal Below 100 mg/dL Below 140 mg/dL Below 5.7% Prediabetes 100 to 125 mg/dL 140 to 199 mg/dL 5.7% to 6.4% Diabetes Above 125 mg/dL Above 199 mg/dL Above 6.4% * The OGTT and HbA1c are both simple tests.
Table 3 The mean and standard deviation of fasting blood glucose and blood glucose in oral glucose tolerance test (GTT) in nondiabetic case of lichen planus.
After glucose stimulation, the acute insulin secretary response (AIR[sub]0′~10′)[sup][9], I[sub]P/I[sub]0,[sup][5] and the area under the glucose curve of intravenous glucose tolerance test (AUC[sub]ins-IVGTT)[sup][10] were adopted to assess the first-phase insulin secretion.
Numbers of other screening tests are also available including glycosuria random blood sugar levels fasting blood glucose level timed sugar testing glycoslated haemoglobin but they are less sensitive in detection of diabetes.2 Finally glucose tolerance test (GTT) was used as confirmatory test for the diagnosis of diabetes.
The chart below contains the FPG test's blood glucose ranges for prediabetes and diabetes: Blood Glucose Range Diagnosis 100 to 125 mg/dL Prediabetes (also called Impaired Fasting Glucose) 126 mg/dl or more Diabetes mellitus (typs 2 diabetes) Oral Glucose Tolerance Test (OGTT) This test measures how well the body handles a standard amount of glucose.
KRG treatment decreased 75g-oral glucose tolerance test plasma glucose indices by 8-11 %, and fasting-plasma insulin and the 75g-oral glucose tolerance test plasma insulin indices by 33-38%, and increased fasting-insulin sensitivity and 75g -insulin sensitivity indices by 33%;, compared with placebo (p < 0.05 for all measures).
Toward universal criteria for gestational diabetes: the 75-gram glucose tolerance test in pregnancy.
The prior criteria for diagnosing diabetes relied heavily on performing an oral glucose tolerance test (OGTT).
When they gave subjects the glucose tolerance test, a standard measure of how well the body processes sugar, they found 326 women had impaired glucose tolerance -- flawed glucose metabolism that leads to Type II diabetes in some cases.
(13) If patients were not diabetic, an Oral Glucose Tolerance Test (OGTT) was performed in the morning after an overnight fast as recommended by the National Diabetes Data Group.
The metabolic syndrome group was obese and at high risk of developing diabetes (as determined by a glucose tolerance test).
