My favourite topic I think my cpeptide might have been 265, with bg of 18 at the time.
Basically it all depends on your bg. If when you had that cpeptide taken your bg was normal and you hadn’t eaten then it points to t2
If your bg was high at the moment you had that cpeptide taken eg you’d just eaten or were high as always are, then you fall into the intermediate range. A T2 would fairly reliably produce more insulin than that, and a T1 would fairly reliably produce less, unless still in honeymoon.
I fell in that intermediate zone 15+ years after diagnosis, I only had one weakly positive antibody. They’ll likely take the overall picture into account, you do have some other pointers that it might be T1, if you have any antibodies that will make it more certain. I was left as a type ? for a while after my cpeptide and antibody test, before we decided to record it formally as type 1, and informally keep it as a ?
