| Clinical Use | <p>Evaluate residual beta cell function in patients with diabetes mellitus treated with insulin; investigate possible surreptitious injection of insulin. C-Peptide can be used in assessment of beta-cell activity in insulin-treated diabetes mellitus. Progressive exhaustion of beta-cell reserves, as monitored by C-peptide level, can be used to measure metabolic stability or "brittleness" of diabetes mellitus. In transient diabetes mellitus, the return of C-peptide concentrations to within the normal range provides evidence of remission.</p> |
