This test is ideal if you're experiencing unexplained low blood sugar episodes, have been diagnosed with diabetes and want to understand how much insulin your body is making, or if your doctor suspects an insulin-producing tumor. It helps distinguish between type 1 and type 2 diabetes, monitors pancreatic function after transplants, and clarifies whether blood sugar problems are due to your body's own insulin production or external insulin. Many people use this test to get a clearer picture of their diabetes management strategy.
You'll need to fast for 12 hours before your blood draw. This means no food or beverages except water during this time. Fasting ensures accurate C-Peptide measurement since eating affects insulin and C-Peptide release. Schedule your test for early morning so you can fast overnight, and bring any medications to take after your test is complete.
This test measures C-Peptide, a protein released by your pancreas when it produces insulin. C-Peptide levels reveal how much natural insulin your body is making, which is crucial for understanding the root cause of blood sugar imbalances and distinguishing between different types of diabetes. Unlike insulin measurements, C-Peptide provides a more stable and accurate picture of your pancreatic function, making it invaluable for diagnosis and ongoing diabetes management.
What this means
Your C-Peptide level is below the optimal range, indicating that your pancreas is producing less insulin than ideal. This may suggest diminished pancreatic beta cell function, which is common in type 1 diabetes or advanced type 2 diabetes, and may explain difficulties with blood sugar control.
Recommended actions
Discuss insulin therapy options with your healthcare provider or endocrinologist
Focus on a balanced diet with consistent carbohydrate portions to manage blood sugar
Monitor your blood glucose regularly to track patterns and response to meals
Consider retesting C-Peptide in 3-6 months to monitor pancreatic function trends
