2024年8月16日 · What is a glucose tolerance test? A glucose tolerance test (GTT) is a test that checks to see if your body can use and store glucose (sugar) as it should. Healthcare providers most often use this test to diagnose diabetes. But there are other diabetes diagnostic tests, like an A1C test and fasting blood sugar test, and other purposes for a GTT.

2024年5月3日 · Results. Results of the glucose tolerance test are given in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Type 2 diabetes or prediabetes. If you're being tested for type 2 diabetes or prediabetes, two hours after drinking the glucose solution: A healthy blood glucose level is lower than 140 mg/dL (7.8 mmol/L).

2023年4月23日 · A glucose tolerance test (GTT) is a procedure that determines whether a patient can use and store glucose normally. The test is usually used to test for diabetes mellitus, insulin resistance, impaired pancreatic beta cell function, and sometimes reactive hypoglycemia or acromegaly, or rarer disorders of carbohydrate metabolism. [2]

The glucose tolerance test is a lab test to check how your body moves sugar from the blood into tissues like muscle and fat. The test is often used to diagnose diabetes. Tests to screen for diabetes during pregnancy are similar, but are done differently. The most common glucose tolerance test is the oral glucose tolerance test (OGTT).

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; fasting...

Here are the general ranges for a normal test result, based on the most common oral glucose tolerance test (OGTT): If your blood glucose levels are higher than normal at any stage of the test, your healthcare provider may diagnose you with pre-diabetes or diabetes.

A GTT should not be performed if: The patient is ill. The test is invalid in the presence of intercurrent illness (e.g. infection), or. The patient has symptoms suggestive of diabetes mellitus, with either fasting plasma Glucose ≥7.0 mmol/L or random plasma Glucose ≥11.1 mmol/L, or two results in these ranges in the absence of symptoms.

2024年3月21日 · What do the results of a GTT indicate? The GTT results indicate how effectively the body processes glucose. Normal levels signify efficient glucose metabolism, while high levels suggest diabetes or impaired glucose handling.

2024年12月10日 · The glucose tolerance test results are used to diagnose and monitor conditions related to blood sugar regulation. The results are typically interpreted as follows: normal glucose tolerance, impaired glucose tolerance, or diabetes. The specific values used to diagnose these conditions are: fasting blood glucose level < 92 mg/dL, 1-hour level ...

The OGTT normal range for fasting results is between 100 – 125 mg/dL for prediabetes, 126 mg/dL or greater for diabetes and greater than 92 mg/dL for gestational diabetes.
