A glucose tolerance test is a health check examination in which glucose is given and blood samples taken after that to cease off how quickly it is cleaned from the blood.[1] The test is regularly used to investigate meant for diabetes, insulin resistance, and occasionally reactive hypoglycemia or rarer disorders of carbohydrate metabolism. In the most commonly performed version of the test, an oral glucose tolerance test (OGTT), a standard dose of glucose is ingested by mouth and blood levels are checked two hours late

Pregnancy Glucose Tolerance Test,

To undergo the Pregnancy Glucose Tolerance Test, the patient should be in fast for the duration of the past 8-14 hours. Only water is permitted. The test begins in the morning hours. The point in time is approximately in the interior 0700 am to 0800 am. This is because the glucose tolerance exhibits a diurnal time with a sensibly a good amount of decrease   all the way through the afternoon time. Then a zero point in occasion blood sample is drawn. The patient is again prearranged glucose solution to gulp. Blood is taken at regular intervals for measurement of glucose and sometimes even insulin levels


Normal blood values for a 75-gram oral glucose tolerance test used to check for type 2 diabetes:

  • Fasting: 60 -100 mg/dL

  • 1 hour: less than 200 mg/dL

  • 2 hours: less than 140 mg/dL. Between 140 – 200 mg/dL is calculated impaired glucose tolerance (sometimes called “prediabetes”). This group is at improved risk for increasing diabetes. Bigger than 200 mg/dL is a sign of diabetes mellitus.

Normal blood values for a 50-gram oral glucose tolerance test used to screen for gestational diabetes:

  • 1 hour: equal to or less than 140 mg/dL

  • Glucose tolerance test diabetes

  • The glucose tolerance test is a physical situation to  check test  in which the glucose is given abnormally to the person to be experienced and after that blood samples are taken to finish how rapidly does the body absorbs it or it gets cleared. It is been done in particular intervals to determine glucose tolerance of a particular body. The test is usually done to test diabetes,

Fasting blood glucose test

The fasting blood glucose plane 70 to 100 mg/dl, in the meantime your blood sugar level  should be checked later than two hours should be a reduced amount of than 140 mg/dl. If your blood glucose level would be in the middle of 140 and 200 mg/dl, then you may contain pre-diabetes ( or impaired blood glucose level). If you come out with consequences more than 200 mg/dl, then you may think the opportunity to have diabetes. But to verify this, you must do once more the test. On the other hand, high levels of blood glucose may draw from from additional health problems. For this you must make certain with your physician
