How reliable is the Glucose tolerance test in diabetes?

Glucose tolerance test in diabetes is more effective in diagnosing gestational diabetes. The test can be effective in diagnosis of diabetes 2. But it may be necessary to administer it several times. Some individuals who test outside the normal range may not develop diabetes if they adjust their eating and physical fitness habits. Regarding long -term accuracy, the test tolerance of glucose to diabetes is good in predicting possible development of the disease.

The purpose of the Glucose tolerance test on diabetes is to measure how the individual's system reacts to a high level of sugar. If the pancreas is unable to produce enough insulin to control the amount of blood sugar levels that circulate at once, these levels may become more than 140 milligrams per deciliter (mg/dl). Anything between 140 and 199 mg/dl indicates glucose intolerance, which is considered to be a pre-diabetes condition. When the Glucose tolerance test in diabetes brings 200 mg/dl or more, this may indicate that the individual has fully developed illnessand.

In order to be as effective as possible, the glucose tolerance test must be administered under certain conditions. The patient should be affected for at least eight hours before the test. Anyone undergoing glucose tolerance testing must be aware that results can be influenced by other underlying diseases or conditions. Some doctors recommend consuming a high carbohydrate diet at least three days before the test.

When the test results indicate that the patient may have type two diabetes, a second or third test can be given to confirm the diagnosis. This is because there are so many circumstances that could distort the test results, including the level of physical activity, slight illness, inability to properly and timing. Some results of individual tests may indicate borderlohladins of blood glucose, which may need to be re -checked and evaluated accuracy.

Glucose tolerance tests do not necessarily have to be administered to diagnose diabetes 2. They tend to be used to determine whether a woman has developed diabetes as a result of her pregnancy. The test is usually given to someone who has a good medical history is relatively physically active and is not on any prescription medicines that could distort the results. Drinking coffee and cigarette smoking on the day of the test can also dramatically change the accuracy of the test.
