A standard OGTT typically uses a 75-gram glucose solution for the test.
What is the primary purpose of the oral glucose tolerance test (OGTT)?
The OGTT is used to diagnose diabetes and prediabetes by measuring how well the body processes glucose.
What should a patient avoid before taking the OGTT to ensure accurate results?
Patients should avoid intense physical exercise before the OGTT as it can affect blood glucose levels and skew the test results.
What is considered a normal blood glucose level two hours after drinking the glucose solution?
A normal blood glucose level two hours after drinking the glucose solution is below 140 mg/dL.
Which hormone's function is primarily assessed by the OGTT?
The OGTT primarily assesses the function of insulin, which is responsible for regulating blood glucose levels.
How many hours of fasting are required before taking the OGTT?

In which population is a 100-gram glucose solution used for the OGTT?

A blood glucose level between 140 and 199 mg/dL two hours after the OGTT indicates:
A blood glucose level between 140 and 199 mg/dL indicates impaired glucose tolerance, which is a sign of prediabetes.
What blood glucose level two hours after the OGTT confirms a diagnosis of diabetes?
A blood glucose level of 200 mg/dL or higher two hours after the OGTT confirms a diagnosis of diabetes.
