Ulta Lab Tests

C-Peptide Response to Glucose Test 6 Specimens

The C-Peptide Response to Glucose Test with 6 specimens measures pancreatic beta cell activity and insulin secretion at six timed intervals. Tracking C-peptide levels across multiple points provides a detailed profile of insulin production, glucose regulation, and metabolic health, supporting assessment of insulin resistance, hypoglycemia, diabetes risk, and overall endocrine function.

The C-Peptide Response to Glucose Test 6 Specimens test contains 1 test with 2 biomarkers .

C-Peptide is useful in distinguishing insulin-secreting tumors, i.e., insulinomas, from exogenous insulin administration. C-Peptide concentrations are severely depressed or absent in Type 1 diabetes mellitus. C-Peptide is also useful in monitoring patients who have received islet cell or pancreatic transplants. It is also measured as an additional means for evaluating glucose tolerance and glibenclamide-glucose tests.
