The positive antibody test indicates that you have the “Potential” for type 1 diabetes. The C-Peptide test indicates you are making enough insulin with a high A1C, which indicates insulin resistance (type 2).

A low C-Peptide (below normal) test along with a high fasting glucose (higher than normal, but less than 255) qualifies you for medicare type 1 classification.

From my understanding, low c-peptide and a reasonable normal fasting glucose also qualifies by Medicare’s standard – at least when it comes to reimbursement for insulin pumps and supplies (which is probably the most important reason to care about the label at that point). (Specifically, “CMS has determined that fasting C-peptide levels will only be considered valid when a concurrently obtained fasting glucose is ≤ 225 mg/dL. Insulinopenia is defined as a fasting C-peptide level that is less than or equal to 110 percent of the lower limit of normal of the laboratory’s measurement method.” (see: NCA - Insulin Pump: C-Peptide Levels as a Criterion for Use (CAG-00092R) - Decision Memo)
Indeed. And it’s worth noting that T1 with insulin resistance is not at all unheard of today. It’s quite possible.
