OK I talked to them and they have the same package with the NMR for a little more and its only $30 more to add the fasting glucose.

I remember reading that what you eat in the days leading up to the test can effect results. I want to get results that are as accurate as possible. Is there anything I can do that will help make the test more accurate? What if I'd been fasting 24 hours when I went for the test, would that make any difference? (I only eat dinner and the lab is not that far away, I could go in the morning or in the afternoon before dinner).
