After an overnight fast, subjects were given a 75-gram oral glucose tolerance test
. Two hours later, a glucometer was used to measure their capillary glucose.
For gestational diabetes testing, a formal oral glucose tolerance test
is indicated if a blood sugar level of >140 mg is achieved following a 50-gram oral dose of glucose.
Regardless, ingesting water during a glucose tolerance test
is not likely to affect the results to any significant degree, and little evidence exists that it should be restricted.
Roughly one in four (23.3%) of those screened for the NAVIGATOR trial via an oral glucose tolerance test
were found to have previously undiagnosed type 2 diabetes.
In a series of 69 women who had glucose tolerance tests
during two or more sequential pregnancies at one medical center, only 1.6% of women with a negative result in their first test had a positive screening result during a subsequent pregnancy, reported Dr.
 All the more reason for generalists and laboratorians to focus more attention not only on the oral glucose tolerance test
but also the hemoglobin Alc assay, which may be useful in diagnosing dysglycemic syndromes of IGT and diabetes.
Exercise tolerance test
has played a central role in the diagnostic workup of CAD for almost a century8.
Among 33 men who had an oral glucose tolerance test
10 to 12 years after entering the study, diabetes or prediabetes develop in 20 (61%): 15 had prediabetes and 5 had diabetes.
Many cases of concurrent diabetes and or patients having impaired glucose tolerance test
results have been reported in lichen planus,8-12 but this association has not been supported in other studies.13,14 We decided to evaluate the frequency of impaired glucose metabolism in our population, and for comparison we have used the study conducted on a general population in Iran by Azizi et al.15
The researchers observed no significant differences between treatment groups at baseline, 12 months, or 15 months in ?-cell function, body mass index (BMI) percentile, hemoglobin A1c (HbA1c), fasting glucose, or oral glucose tolerance test
two-hour glucose results.
The A1c is a simple, relatively inexpensive test that doesn't require the fasting of the standard fasting plasma glucose test or the fasting and waiting time of the two-hour oral glucose tolerance test
Your doctor can check your blood glucose with a fasting glucose test (FGT) or an oral glucose tolerance test
