Hi General, it sounds like you will have a fasting blood test (normally first thing in the morning before eating anything), then eat a meal and then back to the lab for another blood test after 2 hours. You're right. This isn't a troublesome test, and I know you've been through worse. Another test would be the glucose tolerance in which your blood is taken (normally first thing in the morning), then you drink a very sugary liquid, 1 hour and 2 hours later the lab takes another blood test. Good luck with the test. It could be that you are at the very beginnings of diabetes, but these tests are needed to be sure. If this turns out to be true, you'll need to change all those carbs and sugary foods! Let us know what happens, ok?
