Description

Oral Glucose Tolerance Test

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 the diagnosis of impaired fasting glucose and impaired glucose tolerance. This test is also known as the Oral Glucose Tolerance Test (OGTT).

What is the GTT test?

GTT, short for the Glucose Tolerance Test, is a test designed to assess the body response to glucose. In GTT, the patient is given a glucose solution and blood samples are drawn afterword at intervals to measure how well the body cells can absorb glucose. There are several variations to the glucose tolerance test used in different conditions but, the most common one of them is the Oral glucose tolerance test or OGTT.

The OGTT is mainly used in the diagnosis of gestational diabetes. For OGTT, the patient is required to fast for 8-10 hours and then a fasting plasma glucose is tested after that oral glucose solution is given. After that, blood samples can be drawn up to 2-4 times at different intervals to measure the blood glucose. An OGTT is usually performed in the morning as glucose levels normally fall by afternoon.

Why do a GTT test?

OGTT used to be the gold standard in the diagnosis of diabetes type 2 but, is now being replaced with other GTT methodologies. The GTT is primarily used for the diagnosis of diabetes, insulin resistance, impaired beta-cell function, carbohydrate metabolism disorder and also reactive hypoglycemia and acromegaly.

Who needs a glucose tolerance test?

The GTT is usually given to pregnant women during the 24th and 28th weeks of pregnancy. This test is also given to pregnant women who have diabetes symptoms or have the risk of developing diabetes prior to pregnancy.

Besides that, the GTT is also given to other patients who are experiencing symptoms of varied diseases that can cause high glucose levels in the bloodstream or restrict the proper absorption of glucose by the body cells.

What is the procedure for a glucose tolerance test?
  • Have a normal diet like any other day.
  • Fasting is required for 8 to 10 hours prior to the test, and only water is allowed during this period.
  • At first, a zero -time or baseline blood sample is drawn.
  • Then the patient is given a specific dose of glucose solution to drink (Usually 75grm)
  • After that, the blood samples are drawn at regular intervals to measure the blood sugar levels and also insulin levels in certain cases. The blood sampling can be done as requested by the doctor and could involve up to 6 hours of testing (2-4 times).
  • Home Visit Collection Facility Not Available Only For GTT Test. You can include GTT test with other blood and urine tests to avail home collection service.

Glucose Tolerance Test

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 have 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.

What is a GTT test during pregnancy?

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

The Glucose Tolerance Test is scheduled early in the morning. This ensures that the person completes fasting at least 8 hours after dinner. The doctor also may ask you to go off birth control pills and diuretics to avoid 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 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 an 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 are less than 140 mg/dL. Blood sugar levels that are between 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 abnormal, and the woman is diagnosed with gestational diabetes. Elevated blood glucose levels could result from a stroke or a heart attack. Sometimes, the HbA1c test may be ordered instead of the GTT test.

Note:

  • Overnight fasting is required
  • Inform the doctor about the varied prescription drugs you are taking, like certain drugs like corticosteroids, diuretics and antidepressants can cause false results.
  • Doctor’s prescription may be needed
  • The normal test result may vary depending on age, health history, etc.
  • The GTT is not to be done on a sick person
  • Home visit collection facility only for GTT test is not available. Your total test amount should be above Rs999.00 to avail home visit collection service.
