A year ago had a cpeptide test to try and clarify a T1 or T2 diagnosis

The results came back at 600 and my consultant said I was T2... I asked about stopping insulin and she said that may be possible

Friday I saw my DVLA consultant and spoke to him and he said no chance at 600 that is so little it can't happen.. he said at 600 he would give a T1 diagnosis as a T2 should have well over 1000 for a c-pep test.

Any one know much about c-pep and the results

What should I say to my current consultant? Should I be pushing for a T1 diagnosis?

I think I'd be pushing for a second c peptide test.... If it's T1/LADA I'd expect your levels to go down.

I had my c peptide done and I think my level was 400? I am now treated as T1 despite being antibody negative. I think they come to this conclusion as I was only 26, healthy weight and had lost a stone in 3 weeks prior to my diagnosis.

I would push for a second c peptide!

Spoke to a geneticist today who's is going to do another cpep. And depending on the results do genetic testing to get a true type

I am antibody negative healthy weight.. lose weight fas without insulin..

I'm treated as a type 1... but my official diagnosis on my medical records is type2

That’s strange - are you on insulin already?

I think my official diagnosis is ‘insulin dependant diabetic’ so now for ease I just say T1!

Ah yes been on insulin for 9 years. But still been told I'm T2

I need a conclusive T1 or T2 diagnosis

If type 2 then my plans is to withdraw insulin treatment if T1 this obviously isn't possible

But as I said 1 consultant says type 2, another says with low insulin production I'm T1 or some other variant of it ie lada or mody

Just for my information what units are you using? I've had three c-peptide test and they've gone from 1.7 ng/mL to 2.4 ng/mL and back to 1.7 ng/mL. In my case the reference range is 0.8-3.1 ng/mL (or 0.26-1.03 nmol/L), so I'm in range but lower down. I've had my tests done privately, do the NHS use different units. Very confusing!

As a follow up to this.. I had a new c-pep test done by a genetic diabetes consultant and the level had dropped from 629 to 60

Which she said is very low, and she has recategorised me as a type 1 so definitely no getting Off insulin for me
