Oral glucose tolerance testing and cardiovascular disease

Oral glucose tolerance testing.

The oral glucose tolerance test (OGTT) is currently the gold standard for the diagnosis of diabetes. The recommended preparation for and administration of the OGTT are important to ensure that test results are not affected. Interpretation is based on venous plasma glucose results before and 2 hours after a 75 g oral glucose load.

Pathogenetic Mechanisms and Cardiovascular Risk Differences between HbA1c and oral glucose tolerance test for the diagnosis of glucose tolerance

RESEARCHDESIGNANDMETHODSdA total of 844 subjects (44%men; age 49.56 11 years; BMI 296 5 kg/m) participated in this study. Parameters ofb-cell functionwere derived from deconvolution of the plasma C-peptide concentration after a 75-g OGTT and insulin sensitivity assessed by homeostasis model assessment of insulin resistance (IR). Cardiovascular risk profile was based on determination of plasma l...

Prediction of Glucose Tolerance without an Oral Glucose Tolerance Test

Introduction Impaired glucose tolerance (IGT) is diagnosed by a standardized oral glucose tolerance test (OGTT). However, the OGTT is laborious, and when not performed, glucose tolerance cannot be determined from fasting samples retrospectively. We tested if glucose tolerance status is reasonably predictable from a combination of demographic, anthropometric, and laboratory data assessed at one ...

[Fasting glucose versus oral glucose tolerance testing in the diagnosis of diabetes mellitus].

The relationship between diabetes mellitus (DM) and cardiovascular disease is well recognized.1,2 The oral glucose tolerance test (OGTT) (World Health Organization [WHO] 1985 and 1999)3,4 and fasting plasma glucose (FBG) (American Diabetes Association [ADA] 1997 and 2003)5 are both methods for diagnosing DM. The agreement between these methods has been questioned in several epidemiological stud...
