FREE OGT Diagnosing Diabetes Questions and Answers
How long after drinking the glucose solution are blood samples typically taken in the OGTT?
Blood samples are taken at multiple intervals (usually fasting, 1 hour, 2 hours, and sometimes 3 hours) to monitor glucose levels.
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.
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 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.
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.
During the OGTT, what type of solution is the patient required to drink?
The patient drinks a glucose solution to measure how their body processes the glucose over a period of time.
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.
How many hours of fasting are required before taking the OGTT?
Patients are required to fast for at least 8 hours before undergoing the OGTT to ensure accurate results.
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 much glucose is typically used in the solution for a standard OGTT?
A standard OGTT typically uses a 75-gram glucose solution for the test.
In which population is a 100-gram glucose solution used for the OGTT?
A 100-gram glucose solution is used for the OGTT in pregnant women to test for gestational diabetes.
