“The Money Spent on Health is a Worth Pound of Cure”. The progression of medical diagnostics has been highlighting the pursuit of improved well-being, health, deep knowledge, and management of various health conditions. According to the World Health Organisation, it is estimated that in India, nearly 77 million people are suffering from diabetes. Diabetes is a common group of endocrine diseases where the pancreas does not produce enough insulin or cells of the body become unresponsive to the hormone’s effects. Therefore, the article discusses the Glucose Tolerance Test which measures the body’s response to glucose and how exactly your body processes sugar. Unlike other tests, the GTT test is usually prescribed to pregnant ladies. 

Overview of the Article

Among the diagnostic blood tests available today, let us delve into the intricacies and esteemed urgency of GTT in the following article. The document covers:-

  • Complete GTT Test Procedure,
  • The reference levels for a Glucose Tolerance Level,
  • What If Glucose Tolerance Test Results are Present/ Absent,

  • Why is Grace Laboratory a Leader in the field of GTT Blood tests?

Explore the article below and unveil the importance of the most significant test- GTT ( Glucose Tolerance Test) and early detection and timely intervention.

What If Glucose Tolerance Test Results are Present/Absent


What is the Glucose Tolerance Test- The glucose tolerance test serves as a pivotal tool in diagnosing diabetes and assessing glucose mechanism. Subsequently, if the results indicate normal or abnormal glucose tolerance, the information gathered provides valuable insights into your metabolic health. Early detection for people with abnormal results  allows timely intervention and management, potentially preventing complications associated with diabetes. Therefore, we can say that  the glucose tolerance test (GTT) holds significant importance, particularly in assessing how our bodies regulate blood sugar levels. 

What If Glucose Tolerance Test Results Are Present/Absent?- Elevated blood sugar levels throughout the test may suggest that your body is unable to efficiently process glucose, indicating diabetes mellitus. Further tests and evaluations would be needed to confirm the diagnosis and determine the type of diabetes. Some implications are:- 

  •  GTT is performed during pregnancy and the results indicate abnormal glucose tolerance, it may suggest gestational diabetes. This condition requires careful management to ensure the health of both the mother and the baby during pregnancy.
  • If your GTT results show normal glucose tolerance, it generally indicates that your body is effectively processing glucose. 
  • As medical science advances, the glucose tolerance test remains a cornerstone in the proactive management of metabolic health, empowering individuals to take charge of their health outcomes through informed decisions and lifestyle choices.

If your glucose level is in the normal range, it means your body is effectively managing the glucose. However, on the other hand, if the patient has an elevated glucose level, it may point to impaired glucose tolerance. The GTT test results can also indicate a hypoglycemic condition if you have a low blood sugar level. Please refer to the below paragraph to commiserate the reference level.

Understanding The Reference Level To Determine the Glucose Level

It is important to note the reference level as it indicates that your body is not effectively processing the glucose developing the risk of prediabetic, gestational diabetes, hypoglycemic conditions, kidney failure, and heart stroke. The GGT test detects Type 1, Type 2, and Gestational Diabetes. The below paragraph determines the normal and abnormal levels of blood glucose to understand how well your body can metabolize glucose.

Normal Range- The range for Type 1, Type 2, and Gestational Diabetes is:-

  • Fasting Glucose Level: 60 to 100 mg/ dL
  • One- hour Glucose Level: Less than 200 mg/ dL
  • Two- hour Glucose Level: Less than 140 mg/ dL
  • Gestational Diabetes: Less than 90 mg/ dL 


Diabetic Glucose Level- The range for Type 1, 2 and Gestational Diabetes is:-

  • Fasting Glucose Level: 100 to 125 mg/ dL
  • Two- hour Glucose Level: 140 to 200 mg/ dL
  • Gestational Diabetes: More than 95 mg/dL


Glucose Tolerance Test During Pregnancy- This is considered a common routine glucose screening test in modern science. Your healthcare provider can recommend a GGT test before the 24th and 28th week of pregnancy to reduce the risk to both mother and baby. If the pregnant lady is detected with gestational diabetes, the GTT test is recommended much earlier. This test is generally performed to diagnose gestational diabetes and early detection can ensure a healthy pregnancy.  

Please note that the reference level slightly varies from laboratory to laboratory. You can discuss it with your doctor to understand more about the Glucose Tolerance Test Results.

How to Prepare for GTT Test Procedure

In order to get an accurate result it is advisable to maintain a normal diet followed by your day-to-day activity for atleast three days before the GTT test. The test stands as a significant diagnostic procedure to diagnose diabetes and other conditions related to glucose metabolism. The paragraph clearly explains the complete process from preparation to GTT Test Procedure aiding in the timely diagnosis of chronic conditions. 

  • Before the Test- The individuals should fast for 8- 12 hours before the GTT test to get the accurate and most precise result. Fasting is crucial except for water as recent food intake can influence the GTT result.
  • During the Procedure- Before the test begins, you are asked to drink a glass of concentrated glucose sugar solution, usually up to 50- 75 grams. After two to three hours have passed, a small amount of blood is drawn from the vein to determine and measure the blood glucose level. Normally, the GTT test is a two-three glucose tolerance step as you’re asked to drink the solution again and wait for some time. The whole process is repeated. Please note that for a pregnant woman, the GTT test is recommended before 24 weeks of pregnancy.  
  • After the Test- You can resume your normal activities and regime after the test including eating and drinking. The GTT test results are interpreted in milligrams per deciliter(mg/dL) and you can probably get the results within 24 hours. 

Hence, we can say that the GGT test method is an effective way to get an early diagnosis to reduce the risk of long-term complications. I tried shedding light on every aspect of the test and I hope the article explained the clear insights and addressed all your doubts related to the GTT Test Procedure.
