It's also called a glucose tolerance test and is safe for adults and children. For the test, you drink a syrupy solution after not eating for a while (fasting).

The OGTT assesses how an individual uses glucose over time by measuring the participant’s plasma glucose level before and at defined intervals for 2 hours after drinking a solution containing 75 grams (or 1.75 g/kg) of glucose.

2024年5月3日 · The glucose tolerance test measures the body's response to sugar, also called glucose. Another name for this test is the oral glucose tolerance test. This test can be used to screen for type 2 diabetes or prediabetes before you have symptoms of either condition. Or it can help find out whether diabetes is causing existing symptoms.

Because of the increasing occurrence of diabetes in younger people, NHANES added the Oral Glucose Tolerance Test (OGTT) component to the examination protocol to reassess the prevalence of diabetes and impaired glucose tolerance (IGT) in the U.S. population.

2022年1月11日 · 糖耐量试验（GTT），也被称为葡萄糖耐量试验，是诊断糖尿病的一种实验检查方法。 目前临床中主要有静脉和口服两种，静脉称为 IVGTT，口服就是我们常说的 OGTT。 快速静脉注射葡萄糖会导致血糖浓度在 3 ～ 5 min 内迅速升到峰值，随后呈指数型下降到正常水平。 注射后 10 ～ 30 min 内血糖下降速率可用于确定葡萄糖消失的常数，这就是葡萄糖耐量指标 [2，3]。 注：该方法目前只用于评价葡萄糖利用的临床研究手段，或胃切除患者后，吸收不良综合征等 …

2015年9月22日 · 口服糖耐量试验（ogtt）是口服一定量的葡萄糖后 2 h 内做系列血浆葡萄糖浓度测定，是评价个体血糖调节能力的标准方法，并可了解胰岛 β 细胞的功能。

HOW THE TEST IS PERFORMED? The most common glucose tolerance test is the oral glucose tolerance test (OGTT). The test detect how quickly glucose is metabolized from the bloodstream for use by cells as energy source. The normal rate of glucose clearing depends on the amount of glucose ingested.

The Royal Australian College of General Practitioners (RACGP) recommends an OGTT when the results of fasting or random blood glucose are equivocal (Figure 1): fasting 5.5–6.9; random 5.5–11.0 mmol/L.1 An OGTT is unnecessary if fasting or random blood glucose values are clearly in the nondiabetic or diabetic range: fasting or random <5.5 ...
