A member asked:

What are the normal values for serum insulin in glucose tolerance test (75g) after 60 and 120 minutes?

A doctor has provided 1 answer

Serum insulin: levels are very unreliable and of almost no use in a GTT. The labs don't measure them accurately either. Insulin is supposed to increase during a GTT and will go up more if you are overweight and insulin resistant. There are so-called "normals" but they are inaccurate and worthless.
