GTT

GTT or Glucose Tolerance Test is a medical test used to diagnose diabetes or prediabetes. It measures the body's ability to metabolize glucose, a type of sugar that is the primary source of energy for cells.

Procedure

The GTT is usually performed in the morning after an overnight fast. The patient is given a drink containing a certain amount of glucose, and blood samples are taken at specific intervals to measure the blood glucose level. The standard intervals are before the test (fasting), and 1 hour, 2 hours, and 3 hours after drinking the glucose solution.

Interpretation

The results of the GTT are interpreted based on the blood glucose levels at the different intervals. If the blood glucose level is above a certain threshold at any of the intervals, it may indicate diabetes or prediabetes.

Risks and Complications

While the GTT is generally safe, it may cause some side effects such as nausea, vomiting, or fainting. It may also cause a temporary increase in blood sugar levels, which can be harmful for people with certain conditions such as gestational diabetes.
