About the C-Peptide, Blood Test
A C-peptide blood test measures C-peptide, a small protein released in equal amounts with insulin when the pancreas produces the hormone. Because C-peptide stays in the blood longer than insulin and is not present in injected insulin, it gives a reliable picture of how much insulin the body is making on its own. The test helps distinguish type 1 from type 2 diabetes, investigate episodes of low blood sugar, evaluate insulinomas, and monitor beta-cell function after pancreatic surgery.
Who this test may be right for
- People being evaluated for the type of diabetes they have
- Individuals with unexplained low blood sugar episodes
- Patients with a suspected insulin-producing tumor
- People being monitored after pancreatic surgery or injury
- Individuals with suspected insulin misuse
What this test measures
- C-Peptide A marker released with insulin that reflects the pancreas's own insulin production.
Before your visit
- Fasting is often required; follow the instructions included with your order
- Tell the phlebotomist if you use insulin or diabetes medications
- Timing relative to meals may matter; collect when advised
- Report any recent illness or stress, which can affect results
Understanding your results
A low C-peptide level suggests the pancreas is producing little insulin, as seen in type 1 diabetes or advanced beta-cell failure. A high level indicates the body is making excess insulin and can occur with insulin resistance, type 2 diabetes, or an insulinoma. Levels are interpreted with glucose and clinical history. Discuss your C-peptide result and what it suggests about your insulin production with a healthcare provider.

Why measure C-peptide instead of insulin?
C-peptide is released with insulin and is not present in injected insulin, so it gives a clearer measure of the insulin your pancreas makes on its own.
Does injected insulin affect C-peptide results?
Injected insulin does not directly raise C-peptide. This is why C-peptide can help show whether low blood sugar is caused by the body's own insulin or by external insulin.
