C-peptide and antibody testing

Hello fellow sufferers. I was diagnosed a year and a half ago with type 1 (I’m young, healthy/normal BMI, no family history of either T1 or T2, experienced large amounts of weight loss prior to diagnosis along with the polydipsia, polyuria, exhaustion, etc —> so type 2 was ruled out pretty quickly).

I’ve been on 3U of long lasting insulin/day since then, with no fast acting (although I only end up taking it about twice a week). A1C at diagnosis was 18, since then it's ranged from 5.5 - 7. About a year ago, I had two GAD65 antibody tests, both came back with elevated levels (second was done for confirmation). I just had a c-peptide done - 1.96nmol/L, with provided reference ranges for non-diabetic patients being between 0.5 - 0.9nmol/L for nondiabetic patients. Does anyone know what to make of this? My doctor's said to enjoy it, but I was wondering if anyone has had similar surprising labs.
