C- Peptide result is normal :) is this a false hope?

Not really knowing what's going on inside my Endocrine system!!!
I was asked to fast for insulin testing recently.

I'm sure I recall the Diabetologist saying they wanted to check if I was 'making enough insulin' and 'if it was being used properly'

I asked the nurse who took my blood what various things will be looked at and she said something about C-Peptide (google has helped me understand what this is).

Well, my GP told me yesterday my insulin production is normal. Great news right? So I'm making it but my body's not using it properly and I believe 'insulin resistance' is a typical sign of T2.

Is having a normal C-Peptide result typical for a recently diagnosed T2?
 
How long is a piece of string!
This is a far better account of the difficulties in interpreting C peptide than I could do. It's a blog so
google ' diabetes update What does that C-peptide test result mean?
 
Thanks Pheonix I read that blog thanks, it gives a nice clear run down on this type of tests and what the results could indicate - in general though, the internet's giving me conflicting opinions.

Some are cynical on the way the C Peptide levels are tested in the lab.
Seemingly it's even more unreliable if folk are on insulin already (I'm not on any meds yet)
Some say normal to high C Peptide levels are indicative of T2.
Some say normal C Peptide with moderately high glucose levels or well controlled but moderate glucose levels indicates MODY.

Internet information seems to say that a normal result still doesn't help to identify if the beta cells are functioning adequately unless the C Peptide is low which is T1 - so clearer indicator for T1 rather than other forms of Diabetes.

Did you get this test done?
 
Yes, but I was in hospital with some symptoms of DKA, high ketones and high glucose level .. don't know how high I was after eating but the fasting test that decided they needed to admit me was 385mg/dl (21.3mmol/l). The GP wa sceptical when I told him I thought I had diabetes (don't blame him he'd never seen me before and I was very, very thin by then). He told me to go to the lab for a fasting test next day and said that if the results were above 126mg/dl to come back , I think he thought he'd never see me again. (in fact, he's only seen me once more in 6 years, my diabetologue seems to act as my GP!) The lab faxed the results to him and by midday I was in a hospital bed. They took 'armfuls' of blood and that was one of the tests. I only know it was 'negative', though I'm pretty sure that like most people diagnosed as adults I have a bit of beta cell function still there.
 
I'm so sorry to hear about the traumatic experience you go through and then trying to tell the GP the obvious problem.

I'm very lucky that I've not experienced that high a level or the DKN/ketones etc.

I'll just need try and have faith in the Diabetologist, at least he's trying out various tests and not rushing to a conclusion and sending me off with a potential misdiagnosis.
