C-Peptide Blood Test

C-Peptide provides early insight into pancreatic function and insulin resistance. Proactive testing supports early detection of metabolic changes before diabetes develops.

Doctor's Assessment Included

C-Peptide: what this test measures

This test measures the level of C-Peptide in your blood. Since C-Peptide is produced in equal amounts to insulin, it reliably reflects your pancreas's insulin-producing capacity.

C-Peptide: why this value matters

C-Peptide helps distinguish between type 1 and type 2 diabetes and assesses how well the pancreas is functioning. It can also help evaluate insulin resistance. Consult your healthcare provider for interpretation.

C-Peptide: when is testing worthwhile?

Testing may be recommended to evaluate pancreatic function, distinguish diabetes types, monitor insulin-producing tumours, or assess unexplained low blood sugar episodes.

C-Peptide: symptoms of a high or low value

Low Levels

Low C-Peptide may indicate that the pancreas is producing little or no insulin, which is typical of type 1 diabetes. Symptoms may include excessive thirst, frequent urination, and weight loss.

High Levels

High C-Peptide may indicate insulin resistance, type 2 diabetes, or an insulin-producing tumour. Symptoms may include weight gain, fatigue, and difficulty managing blood sugar levels.

C-Peptide: lifestyle and this value

Regular physical activity, a balanced diet with controlled carbohydrate intake, maintaining a healthy weight, and managing stress can all support healthy insulin function and C-Peptide levels.

C-Peptide: frequently asked questions

Why test C-Peptide instead of insulin?
C-Peptide is more stable in the blood and is not affected by injected insulin, making it a more reliable measure of your body's own insulin production.
Can C-Peptide help diagnose diabetes type?
Yes, low C-Peptide suggests type 1 diabetes (insufficient production), while high levels may suggest type 2 diabetes (overproduction due to resistance). Your healthcare provider can confirm.
Do I need to fast for this test?
Fasting may be required depending on the clinical question. Your healthcare provider will advise on preparation.
