I'm scheduled to have an OGTT on Friday, and I'd appreciate if anyone could reply today or tomorrow.

The doctor told me they'd be checking my Glucose and C-Peptide levels during the 3-hour test, because I occasionally have hypoglycemic symptoms.

My fasting glucose has been in the range of 100-106 (5.6-5.9mmol/L) in the past 8 years, except for a couple of times when it went as high as 111 and 115 (6.2 and 6.4mmol/L). I'm not on any medication, have never been.

Now, my question is whether measuring only the C-Peptide levels without Insulin is enough for an accurate diagnosis of whatever I have.

I'd like to add that in my country I'm free to choose whatever test I want to undergo, so I may just pay for Insulin and have that done, too. But in that case, does it make sense to have C-Peptide and Insulin tested at every hour, alongside Glucose?

The only reason I'm not very enthusiastic about doing both C-Peptide & Insulin is the cost. I'll have to pay for each test as if it were a routine one, not a part of the OGTT.

Thanks for any input.

Editing to say oops I noticed I mistyped OGTT in the title, but hope it's not too misleading. I just can't change it.
