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...

Impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) represent intermediate states between normal fasting glucose (NFG) or normal glucose tolerance (NGT), respectively, and diabetes (1). The regulation of fasting and glucose concentrations after an oral glucose load is dependent on different physiological mechanisms (2), and current evidence suggests that IFG and IGT have differe...

The present study was planned to elucidate the role of fasting on the intestinal absorption of monosaccharides particularly--glucose and xylose in inbred female albino rats. Rats (weighing 250-300 grams) were divided into three groups. One group of rats served as control while the other two were experimental. One of the experimental groups was starved for 48 hours while the other for a period o...

OBJECTIVE To evaluate the role of adiposity in the relationship between specific and surrogate estimates of insulin-mediated glucose uptake (IMGU) in a large nondiabetic population. RESEARCH DESIGN AND METHODS Healthy volunteers were classified by BMI into normal weight (<25.0 kg/m(2), n = 208), overweight (25.0-29.9 kg/m(2), n = 168), and obese (>or=30.0 kg/m(2), n = 109) groups. We then ass...

We previously reported that type 2 diabetes risk, early impaired glucose tolerance and insulin resistance can be predicted by measuring the fasting levels of certain biomarkers. Here we validated these findings in randomly recruited healthy volunteers (n = 101) based on biomarker expression as well as various non-invasive indices. Weight, body mass index, waist circumference and visceral fat di...

BACKGROUND Helicobacter pylori infection raises basal and meal stimulated serum gastrin concentrations and lowers iron stores, which may in turn reduce fasting plasma glucose concentrations in the population. AIM To determine whether H pylori infection leads to lower fasting plasma glucose concentrations in the population. METHODS One hundred and seventy three women and 165 men, randomly se...

background a fall in plasma concentration of energy status related hormones (leptin, insulin-like growth factor-1 (igf-1) and insulin) and body energy expenditure occurs in response to short term fasting. nevertheless, the relations of the fasting-induced changes in energy related hormones and metabolites with fasting energy expenditure (fee) under extended fasting condition have received littl...

OBJECTIVE Although A1C is now recommended to diagnose diabetes, its test performance for diagnosis and prognosis is uncertain. Our objective was to assess the test performance of A1C against single and repeat glucose measurements for diagnosis of prevalent diabetes and for prediction of incident diabetes. RESEARCH DESIGN AND METHODS We conducted population-based analyses of 12,485 participant...

OBJECTIVE This study determined the relationship between fasting glucose levels of cerebral infarction patients and the hospitalization time and relapse and mortality rates. METHODS A retrospective study was conducted between February 1996 and December 2006 involving 974 inpatients with cerebral infarctions. Fasting blood glucose and lipid levels and blood pressure were measured the morning a...

OBJECTIVE To determine the feasibility of using either fasting plasma glucose or HbA(1c) to identify individuals in the U.S. population who meet the Diabetes Prevention Program (DPP) criteria for intervention, defined as BMI >/=24 kg/m(2), fasting plasma glucose level 96-125 mg/dl, and 2-h glucose level 140-199 mg/dl in an oral glucose tolerance test (OGTT). RESEARCH DESIGN AND METHODS Analys...
