Glucose Tolerance Test (GTT) Cost

Glucose Tolerance Test finds the body's response to sugar. This test is used as a screening tool for Type-2 diabetes as well. The Glucose Tolerance Test should be reserved principally for patients with “borderline” fasting plasma glucose levels. The test is necessary for diagnosis of impaired fasting glucose and impaired glucose tolerance. This test is also known as Oral Glucose Tolerance Test (OGTT).

The Glucose Tolerance Test is ordered to find Type-2 diabetes in a person or if an expecting woman has gestational diabetes. If you are pregnant and have a body-mass index, that is more than 30kg/meter square, you may be having gestational diabetes. If you are an expecting woman and your parent/sibling has diabetes, then that ups the risk of gestational diabetes for you as the expecting mother.

All pregnant women should be tested for gestational diabetes millitus with a 50-g dose at 24 to 28 weeks of pregnancy; if that is abnormal, OGTT should be performed for confirmation and is gold standard for diagnosis of gestational DM.

The Glucose Tolerance Test is generally scheduled early in the morning. This ensures that the person completes fasting of atleast 8 hours after dinner. The doctor also may ask you to go off birth control pills and diuretics for avoiding results to be affected by their presence in the body. If you are on drugs for any mental disorder or neurological problems, those medications need to be discontinued with the doctor's consent.

A blood sample is taken from the person's arm for testing. If you are a pregnant woman getting yourself tested for diabetes, you may be asked to do 8 hour fasting. You will be asked to drink about 100 grams of sugar. The blood sugar levels are checked in 3 hours. If type-2 diabetes is being checked, the person is made to drink 75 grams of sugar and blood sugar levels are checked after 2 hours.

Normal blood sugar levels for Type-2 diabetes is less than 140 mg/dL. Blood sugar levels that are in range of 140mg/dl- 199 mg/dl are precursors to type-2 diabetes. Likewise, a blood sugar level below 95 mg/dl is normal for pregnant women. Any blood sugar levels that range in 140 mg/dl-180 mg/dl are considered as abnormal and the woman is diagnosed with gestational diabetes. Elevated blood glucose levels could be as a result of a stroke or a heart attack. In some cases, HbA1c test may be ordered instead of GTT test.

Glucose Tolerance Test (GTT) FAQs
Q: What is glucose tolerance test?
A: Glucose tolerance test (GTT) is a method to determine the presence of diabetes. This test has great value in diagnosing gestational diabetes.
Q: Why is glucose tolerance test needed?
A: Apart from diabetes, a GTT helps in diagnosing impaired function of beta cells (in pancreas), reactive hypoglycemia & acromegaly, insulin resistance or diseases affecting metabolism of carbohydrates.
Q: Is there any special preparation required before a Glucose Tolerance Test?
A: Yes. In the few days before testing you will be asked to have a good carbohydrate diet. Fasting is required for 8-12 hours before the test. Preferably you should not be ill and avoid medications like oral contraceptives, salicylates, diuretics and anti-convulsants for some time (only after getting the approval of your doctor).
Q: How is GTT performed?
A: Some blood is withdrawn from the vein and marked as baseline sample. A certain amount of glucose is given in solution form to drink, 2 hours after which another blood sample is taken. If renal glycosuria is suspected, urine samples may also be taken at same time intervals.
Q: What do the results of a GTT indicate?
A: A GT test shows the levels of glucose and the person's ability to metabolize it. The results of GTT in different conditions are indicated below:
In absence of diabetes
  • Fasting glucose – Less than 100 mg/dL
  • 2 Hour glucose – less than 200 mg/dL
Impaired Glucose Tolerance (Prediabetes)
  • Fasting glucose – Less than 126 mg/dL
  • 2 Hour glucose – Between 140 mg/dL – 199 mg/dL
  • Fasting glucose – more than 126 mg/dL
  • 2 Hour glucose – more than 200 mg/dL
Gestational Diabetes
  • Fasting glucose – more than 92 mg/dL
  • 2 Hour glucose – more than 153 mg/dL
