About the test
C-Peptide is a substance produced in the pancreas, released into the bloodstream in equal amounts to insulin. Measuring C-peptide levels helps assess how much insulin the body is producing, which can aid in distinguishing between type 1 and type 2 diabetes or evaluating insulin-producing tumors (insulinomas).
