C-Peptide, Serum - (QUEST DIAGNOSTICS)

Description: C-Peptide is useful in the evaluation of pancreatic beta cell function (e.g., helping distinguish type 1 from type 2 diabetes mellitus, or monitoring patients who have received islet cell or pancreatic transplants) and for determining the source of insulin in patients with hyperinsulinemic hypoglycemia (e.g., distinguishing insulin-secreting tumors from exogenous insulin administration). It is also sometimes measured as an additional means (more resistant to hemolysis than is insulin itself) for evaluating glucose tolerance tests.

Significant deviations from the normal range may require further evaluation by your physician.

Includes: C-Peptide, Serum

Alternative Name(s):
C-Terminal Insulin
