Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Diagnosis and management of diabetes mellitus
  • ✓Evaluation of suspected insulin resistance
  • ✓Assessment of pancreatic beta-cell function
  • ✓Investigation of hypoglycemia
  • ✓Differentiating between Type 1 and Type 2 diabetes
  • ✓Monitoring response to diabetes treatment

In plain language

What this test helps you understand

Assessing endogenous insulin production, differentiating between Type 1 and Type 2 diabetes, monitoring pancreatic function, evaluating hypoglycemia.
The Cpeptide Fasting Serum Test is a diagnostic procedure used to measure the level of C-peptide in the blood. C-peptide is released in equal amounts to insulin when the pancreas produces insulin. This test is particularly useful for individuals with diabetes to understand how much insulin their body is producing.

This test measures the concentration of C-peptide in the serum after a period of fasting. C-peptide levels can provide valuable insights into pancreatic function and the body's insulin response.

Understanding your insulin production is crucial for effective diabetes management and treatment decisions. This test helps healthcare providers assess pancreatic function and guide appropriate treatment strategies.

Questions people ask

Frequently asked questions

C-peptide is a substance released by the pancreas along with insulin. Measuring C-peptide levels helps assess how much insulin your body is producing.
Fasting ensures that insulin and C-peptide levels are measured under baseline conditions, providing a more accurate assessment of your body's natural insulin production.
Typically, an overnight fast of 8-12 hours is required. Please confirm the exact fasting duration with the laboratory.
High C-peptide levels usually indicate high insulin production, while low levels suggest low insulin production. Your doctor will interpret the results based on your overall health.
This test can help differentiate between Type 1 diabetes (low C-peptide) and Type 2 diabetes (normal or high C-peptide initially), and is used in the management of both.
