A 2-hour oral glucose tolerance test
is far more sensitive than the standard fasting blood glucose test in identifying obese children at increased risk for type 2 diabetes or metabolic syndrome.
The FPG test and the 75-g oral glucose tolerance test
(OGTT) are both suitable tests for diabetes," (1) and
It is widely recognized that diagnosis of diabetes mellitus by fasting plasma glucose (FPG) and the oral glucose tolerance test
(OGTT) are not equivalent.
2) Diagnostic criteria for GDM using the 100-g oral glucose tolerance test
(OGTT) have been defined by the National Diabetes Data Group.
While the oral glucose tolerance test
was previously considered the standard for diabetes screening, diagnosis using hemoglobin A1C does not require a long fast beforehand, making it easier for patients.
Study limitations included the fact that the participants were volunteers and that the researchers used a single glucose tolerance test
as their standard rather than two glucose tolerance tests
The participants underwent an antepartum glucose challenge test (GCT) and a 3-hour oral glucose tolerance test
(OGTT), an assessment of obstetric outcome at delivery, and a metabolic characterization by OGTT at 3 months post partum.
6 mmol/L (119 mg/dL), a 3-hour glucose tolerance test
by venous plasma glucose was arranged within a week.
Participants underwent an oral glucose tolerance test
if they had no history of diabetes, and LV geometry and LV systolic and diastolic function were analyzed by Doppler echocardiography.
In addition, a risk assessment based on history, physical-examination findings, and common blood measures such as lipids and fasting glucose was able to identify three-quarters of the people diagnosed with diabetes using an oral glucose tolerance test
Rhoda Cobin's claim that there were "few arguments against" the recent recommendation of an expert panel that all women with polycystic ovary syndrome be screened for diabetes ("Oral Glucose Tolerance Test
Urged for All PCOS Patients," March 1, 2008, p.
Women who have an abnormal glucose tolerance test
result during pregnancy but do not develop gestational diabetes still face an increased risk of developing type 2 diabetes later on, investigators reported.
