Search Links: General Info : Protocols : Patient Info

DescriptionUrine C-peptide is a simple, practical and non-invasive alternative to serum C-peptide measurement which can easily be performed in the outpatient department and primary care setting (McDonald et al. 2009 Clin Chem). A urine sample collected 2 hours after the biggest meal of the day permits assessment of residual beta cell function and is discriminative between type 1 diabetes and other sub-types of diabetes. For more information, see
