Question

Which test results would best confirm a diagnosis of type 2 diabetes in a symptomatic patient?

Answer 1

The best tests for confirming a diagnosis of type 2 diabetes in a symptomatic patient are the glucose tolerance test (GTT), insulin tolerance test (ITT), and glucagon tolerance test (GuTT).

Step-by-step explanation:

The best tests to confirm a diagnosis of type 2 diabetes in a symptomatic patient include:

1. Glucose tolerance test (GTT): This test is performed on patients suspected of having diabetes mellitus. It measures blood glucose levels after the consumption of a glucose solution to determine how well the body processes glucose.
2. Insulin tolerance test (ITT): This test helps confirm the type of diabetes. Hypoglycemia is seen in cases of Insulin Dependent Diabetes Mellitus (IDDM).
3. Glucagon tolerance test (GuTT): This test is utilized to detect the type of diabetes. If hyperglycemia is observed, it indicates diabetes is due to defective insulin receptors, while no change in blood glucose levels suggests diabetes is due to excessive insulin antagonists.
