There is still disagreement concerning the optimal procedure for the diagnosis of milder degrees of hyperglycaemia in pregnancy. We have compared the results of a 75 g oral glucose tolerance test (OGTT) and a standardised breakfast test performed one week apart in 102 non-diabetic women with a singleton pregnancy. There was poor correlation between the two tests (r = 0.15) at two hours, and nei...

DEFINITIONS Patient (Pt) testing options for glucose testing are shown below. Protocols and interpretations for individual glucose tolerance tests follow along with information on pediatric dosing. All samples are heparinized plasma unless otherwise stated. Provider specifies what patient may eat and when collection is to occur after eating, prior to this draw. No reference range is provided. G...

D of the category of impaired glucose tolerance by the National Diabetes Data Group (NDDG) and by the World Health Organization (WHO) has served to highlight the dearth of knowledge about the significance of glucose tolerance levels that fall short of being diagnostic of diabetes, but that are above normal if these are defined as glucose levels above the mean plus two standard deviations in hea...

UNLABELLED Aims/Introduction:  The computed tomography (CT) value of the pancreas was examined across the range of glucose tolerance, and the relationships between pancreatic CT values and factors responsible for glucose intolerance were analyzed. MATERIALS AND METHODS   A total of 167 health-check examinees were classified into normal glucose tolerance (NGT), impaired glucose tolerance (IGT)...

FIG. l.-Glucose tolerance curves in Subjects 8 and 10, showing pronoi variation in peak blood sugar levels. this impairment, for treatment with a progestational agent alone does not alter glucose tolerance (Puchulu et al., 1967) or may even improve it (Benjamin and Casper, 1966). This suggested the possibility that changes in endogenous oestrogen levels occurring during the normal menstrual cyc...

To estimate the prevalence of glucose intolerance in the elderly, oral glucose tolerance tests were performed as part of the Rotterdam Study, a population-based study in subjects aged 55 years and over. The study population consisted of 2,668 men and 3,950 women. Diabetes mellitus was defined as the use of antidiabetes medication, or a random or post-load serum glucose level of > or = 11.1 mmol...

BACKGROUND AND PURPOSE The prevalence of diabetes is high among patients with ischemic stroke. However, the prevalence of abnormal glucose regulation and clinical characteristics among patients with stroke in the Chinese population is uncertain. We investigated the prevalence of prediabetes and diabetes in Chinese patients after stroke onset in a nationwide cohort study and investigated abnorma...

OBJECTIVE Hyperinsulinaemia is associated with development of chronic metabolic disease and is emerging as a health risk independent to that of insulin resistance. However, little is known to what extent hyperinsulinaemia occurs with normal glucose tolerance in lean subjects. METHOD Oral glucose tolerance tests with concurrent insulin assay were conducted during the 1970s-1990s. Participants ...

OBJECTIVE Type 2 diabetes in obese youth is an emerging problem. The metabolic and anthropometric predictors of change in glucose tolerance status in obese youth are unknown. RESEARCH DESIGN AND METHODS A total of 117 obese children and adolescents were studied by performing an oral glucose tolerance test (OGTT) at baseline and after approximately 2 years. Data from both OGTTs and changes in ...
