The C-peptide fasting test is a blood test that checks the amount of C-peptide present in the bloodstream. C-peptide is released whenever the pancreas produces insulin. Insulin is a hormone made by the beta cells of the pancreas and plays a key role in regulating blood glucose levels. Insulin and C-peptide are released into the bloodstream simultaneously and in equal quantities, which allows this test to help doctors determine how much insulin the body is producing. This test may also be referred to as connecting peptide insulin, insulin C-peptide, or proinsulin C-peptide.

After food is consumed, the body breaks it down into glucose and other nutrients. In response, the pancreas releases insulin, which helps transport glucose from the blood into the cells, where it is either used for energy or stored for later use. For a long time, C-peptide was considered only a by-product of insulin production. However, research has shown that C-peptide can influence the body in different ways and may have pro-inflammatory or anti-inflammatory effects depending on its concentration.

The C-peptide fasting test is useful for evaluating how effectively the body is producing insulin. It helps doctors differentiate between type 1 and type 2 diabetes and understand whether the pancreas is still making insulin. The price of C-peptide fasting may vary from lab to lab. One should always be interpreted by a qualified healthcare professional, who can assess them in the context of symptoms, medical history, and other diagnostic findings to ensure accurate evaluation and appropriate treatment planning.

When is the C-Peptide Fasting Test Prescribed?

A C-peptide test is commonly recommended for individuals diagnosed with type 1 or type 2 diabetes to evaluate how effectively the pancreas is producing insulin. In cases of type 2 diabetes, the test helps monitor beta-cell function and insulin secretion, allowing doctors to determine whether insulin therapy is necessary. It is also used to assess metabolic response and weight-related outcomes following bariatric surgery, as well as to evaluate the potential risk of developing diabetes. The test may be advised if symptoms suggest low blood sugar (hypoglycaemia). These symptoms include:

Blurry vision
Frequent hunger and thirst
Excessive sweating
Lethargy
Heart problems
Difficulty concentrating

How to Interpret the C-Peptide Fasting Test Result?

Understanding the ranges can help in discussing the results more accurately and confidently with the doctor. The normal range for C-peptide levels in the blood is between 0.5 and 2.0 nanograms per millilitre (ng/mL).

C-peptide Level	Interpretation	Possible Implications
Normal	The pancreas is producing insulin at a healthy rate	Indicates normal insulin production and pancreatic function
High	The body is producing excess insulin	May indicate insulinoma or other conditions causing overproduction of insulin
Low	The pancreas is not producing enough insulin	May indicate type 1 diabetes or other conditions affecting insulin production

How To Prepare for the C-Peptide Fasting Test?

Before the C-peptide test, patients fast for 8-12 hours with water only and pause medications as advised by their physician. The C-peptide fasting serum test is suitable for all age groups and requires no special preparation. Individuals can check the fasting C-peptide test price online and schedule the test.

Once the sample is collected, the fasting peptide test results are available on the same-day report if the sample is collected before 2 PM, next-day report if the sample is collected after 2 PM. The fasting C-peptide blood test helps evaluate insulin production, and the fasting serum C-peptide level assists in clinical assessment and treatment planning.

Frequently Asked Questions (FAQ's) about C-Peptide Fasting

The C-peptide fasting test measures C-peptide levels in blood or urine. C-peptide is released by the pancreas when insulin is produced. It is primarily used to evaluate pancreatic beta-cell function, differentiate types of diabetes, and investigate causes of hypoglycemia.

The test is ideally performed in the morning after an overnight fast.

Elevated C-peptide levels may indicate that the body is producing excess insulin. This could suggest conditions such as insulinoma or other disorders causing overproduction of insulin by the pancreas.

Yes, but one should avoid consuming any other beverages, such as juice or cold drinks, during the fasting period.

The price may vary between laboratories. At Max Lab, the fasting C-peptide test costs INR 1100.
