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.
During that period, NHANES conducted oral glucose tolerance tests
of persons in that age group and estimated that 40% of adults aged 40-74 years had impaired fasting glucose, impaired glucose tolerance, or both (2).
Effects of oral glucosamine sulphate on serum glucose and insulin during an oral glucose tolerance test
of subjects with osteoarthritis.
The first protocol was to continue the previously recommended 50-g glucose challenge test with a diagnostic 3-h 100-g oral glucose tolerance test
(OGTT) if the glucose concentration was increased at 1 h after the 50-g load.
But when Dutch researchers gave 13 women with diabetes 1 1/2 grams of ground cinnamon (3/4 teaspoon) every day for six weeks, they did no better on an oral glucose tolerance test
than similar women who were given a placebo.
The prior criteria for diagnosing diabetes relied heavily on performing an oral glucose tolerance test
In this criteria, two or more abnormal glucose values in the 3-h, 100-g oral glucose tolerance test
(OGTT) were considered pathological (3).
In studies that involved those at high risk of the disease, magnesium supplementation was associated with significantly improved plasma glucose levels compared to a placebo following a two-hour oral glucose tolerance test
and a trend toward reduced insulin resistance.
Gestational impaired glucose tolerance (IGT) is defined as an abnormal glucose level obtained in an oral glucose tolerance test
(OGTT) during pregnancy.
This was after adjustment for age, prepregnancy BMI, previous gestational diabetes status, and number of weeks' gestation at the time of the oral glucose tolerance test
, according to a paper published in Diabetes Care.
Objective: To compare efficiency of glucose challenge test with oral glucose tolerance test
for detection of gestational diabetes mellitus (GDM).Methods: This observational cross sectional study was conducted in The Department of Obstetrics and Gynaecology Sharif Medical and Dental College / Sharif Medical City Hospital from December 2012 to June 2013.1000 consecutive pregnant ladies were included during this period between the gestational age group of 26 to30 weeks by using convenient sampling technique after analysis of risk factors.
