C Peptide Results-type unknown

[lcarter]

Hi. I have been a type 1 for 10 years, diagnosed at 26. Recently a registrar thought it would be interesting to do my c peptide bloods as when I was diagnosed my blood test was negative to autoimmunity. So I chased it up today and they've said yes, I am producing some insulin, but they dont know if it's enough. So I've got to do a urine test 2 hours after eating, then they will know.

Has anyone been through this? I know you cant diagnose, but is it even possible that type 1s can still produce insulin?

They are not sure if I'm a type 2.

Thanks

In some cases individuals do continue to produce some insulin, although susually at modest levels, meaning they require insulin, but often not as much as another "average" T1 (whatever average means!).

I personally know of one such person, diagnosed as T1, but still producing insulin after a very long time, but he is not a member here. Others, whether T1, or classified as LADA can find their honeymoon period lasts years. Member @Ian DP is such a person. If you read the detail on his profile, it's interesting.

Some type 1s have a honeymoon where they do still produce insulin. I would look up Honeymoon phase on this forum to find some interesting threads.
No personal experience as I was diagnosed aged 10 and went straight into it but have read in Dr Bernstein's book The Diabetic Solution that a low carbohydrate diet goes some way to preserving beta cell function but cannot recover it it its already low. If you type in Dr Bernstein Type 1 Honeymoon Phase you will get to it (note he is an elderly American in his mid 80s and lived with type 1 since 1948 so be patient!)

From what I've read over the years there is a complete spectrum of T1 insulin production types. The assumption that T1s produce no insulin is not really valid. I've seen posts over the years from T1s who take little insulin yet have good BS control thru to those who obviously have no insulin and really struggle. It would be useful for us all to have c-peptide tests just for interest and perhaps for research purposes but that isn't going to happen.

Hi diagonised type 2 in 2016 things have changed over last 2.5 years bad time end of last year since then been on insulin and recently advised to have c peptic test as like you they feel i may be producing some insulin but not enough therefore could be technically reclassed as type 1 awaiting results of test

Well, in the UK you're probably better off with a T1 diagnosis if only because T1s get better access to NHS treatment (hospital appointments rather than GP clinics, libre prescriptions etc etc). Do T2s on insulin get referred to hospital clinics???

I haven't as of yet only had blood test at hospital
