(3-5) Based upon this analysis and the ADA position statements, laboratorians should not discourage the use of the 2-point (zero time and +2 h) 75-g oral glucose
tolerance test in the diagnosis of diabetes or pre-diabetes if the initial FPG result is not elevated (e.g., <110 mg/dL).
Rhoda Cobin's claim that there were "few arguments against" the recent recommendation that women with polycystic ovary syndrome be screened for diabetes ("Glucose
Tolerance Tests Urged for All With PCOS," Jan.
"It's a big barrier to get them into the system, to get them to the lab to do a formal glucose
tolerance test. This [capillary glucose tolerance test] is a proxy for that.
Physicians must be aware, however, that an abnormal glucose
tolerance test in the absence of fasting glucose levels >140 mg/dL or a two-hour postprandial glucose level of >200 mg/dL indicates glucose intolerance, and not necessarily diabetes.
A: Your question begs a larger one that challenges the usefulness of a glucose
tolerance test (GTT) in the first place.
He reported on 17,532 individuals who underwent an oral glucose
tolerance test as part of the screening process for participation in the Nateglinide and Valsartan in Impaired Glucose Tolerance Outcomes Research (NAVIGATOR) trial.
A woman at low risk of gestational diabetes, based on a negative result from a 1-hour, 50-g glucose
tolerance test, will remain at low risk during a subsequent pregnancy within the next 4 years.
[24] The only way to know whether a patient has IGT is to perform an oral glucose
tolerance test, which, therefore, should be run on subjects with repeated fasting plasma glucose levels exceeding 90 mg/dL (see Table 2, on page18).
Some of the tests that your doctor might require to confirm the condition include a lactose
tolerance test, hydrogen breath test, small bowel biopsy, and milk

All study participants had an initial fasting glucose test and an oral glucose
tolerance test. Both tests measure glucose (sugar) in blood.
Methods: Fifty-two patients with mucosal or cutaneous lichen planus disease were evaluated regarding disease characteristics, fasting blood sugar levels and glucose
tolerance test (GTT) results.
