Glucose Tolerance Test (GTT) - 3 Samples

Glucose Tolerance Test, commonly known as GTT, is an important diagnostic tool used to evaluate how your body regulates blood sugar levels. It is particularly helpful in diagnosing conditions like diabetes and gestational diabetes, a type of diabetes that occurs during pregnancy. The test involves taking blood samples at different intervals after consuming a glucose solution, which helps in understanding how your body is processing glucose.


  • Profile Name: Glucose Tolerance Test (GTT) - 3 Samples
  • Sample Type: Blood
  • Preparations Required: You will need to fast for at least 8 hours before the test. Only water can be consumed during the fasting period.
  • Report Time: 4 hours

In the 3-samples version of GTT, blood is drawn initially to measure your fasting blood glucose levels. You will then be given a sugary drink, and blood samples are taken again at one and two hours after consuming the drink. This provides the doctor with a clear picture of how your body is handling glucose over time.
