Routinely testing for C-peptide when patients with type 1 diabetes visit their treating doctor might result in some of them being diagnosed with a different type of diabetes, researchers say.
Endocrinologists from an outpatient clinic in Edinburgh, Scotland, tested non-fasting C-peptide levels when patients diagnosed with type 1 diabetes mellitus (T1DM) for at least three years came for a routine consultation.
