The C-peptide test measures the amount of C-peptide in the blood or urine. The pancreas releases C-peptide when it makes insulin.

Interesting Facts About Insulin
- Insulin is a hormone produced by the pancreas.
- It regulates blood sugar levels by facilitating glucose uptake.
- Insulin deficiency causes diabetes mellitus.
Here are some purposes of the C-peptide test:
Here are the points for C Peptide Test preparation:
Summary
Before the C Peptide Test and during the test, a blood sample is collected, and afterward, resume normal activities while expecting minor bruising or soreness at the needle site.
Here are the steps of the C peptide test procedure:

The normal range of the C-peptide level may vary depending on the laboratory and the method used for the test.
C-Peptide Level | Interpretation |
---|---|
0.5-2.0 ng/mL | Normal range |
<0.5 ng/mL | Insufficient C-peptide production |
>2.0 ng/mL | Excessive C-peptide production |
It's important to note that C-peptide levels can also be affected by various factors such as age, sex, and medical conditions, so it's always best to consult a healthcare provider for the interpretation of results.
Here is the table format for interpreting C peptide test results:
C Peptide Test Result | Interpretation |
---|---|
Less than 0.5 ng/mL (0.17 nmol/L) | Indicates low insulin production and may suggest type 1 diabetes or advanced type 2 diabetes |
0.5-2.0 ng/mL (0.17-0.66 nmol/L) | Considered normal range |
More than 2.0 ng/mL (0.66 nmol/L) | Indicates high insulin production and may suggest insulin resistance or early type 2 diabetes |
Note: Normal range values may vary slightly depending on the laboratory where the test is performed. It's important to discuss your test results with your healthcare provider.
Here are some of the common causes of high C Peptide levels in a blood test:
Cause | Description |
---|---|
Insulinomas |
Insulinomas are tumors of the pancreas. They make extra insulin, more than your body can use. |
Insulin resistance |
also known as impaired insulin sensitivity, cells in your muscles, fat, and liver don’t respond as they should to insulin |
Kidney disease |
The most common form of kidney disease is chronic kidney disease. |
Cushing syndrome, an endocrine disorder |
Cushing's syndrome is a disorder that occurs when your body makes too much of the hormone cortisol over a long period of time. |
A class of diabetes drugs - sulfonylureas |
Examples of sulfonylureas include:
|
A low level of C peptide means that your body doesn’t produce enough insulin. Here are some of the common causes of low C Peptide levels in a blood test:
Cause | Description |
---|---|
Both type 1 and type 2 diabetes |
People with type 1 diabetes typically have even lower C-peptide levels than people with type 2 diabetes |
Poorly functioning pancreas |
Poor Pancreas functioning means your body does not produce enough insulin |
Fasting for a long period |
Long-period fasting which affects your insulin levels |
Summary
Elevated levels indicate normal insulin production, while low levels suggest impaired insulin production or insulin resistance.
Here are some points on who should get a C peptide test:
Here are the specimen requirements for the C Peptide Test.
Specimen | Blood Serum |
Volume | 1 ml |
Container | Red-top tube or gel-barrier tub |
Here are some limitations of C Peptide Test.
Here are risk factors associated with the C Peptide Test.
Here are Doctor's recommendations or consult a specialist after the C Peptide Test.
C Peptide Test Result | Doctor to Visit | Reason to Visit |
---|---|---|
High levels | Endocrinologist | Assess for insulinoma or insulin resistance |
Normal levels | Primary Care Physician | Monitor overall diabetes management |
Low levels | Endocrinologist/Diabetologist | Evaluate for insulin deficiency or pancreatic disease |

Summary
Overall, C peptide test measures the level of insulin production by the pancreas and can help diagnose diabetes. Also check Drlogy Test for detailed information about all medical tests for patients, doctors, scholers and medical students.
Reference
A C Peptide Test is a laboratory test that measures the level of C-peptide in the blood.
A C Peptide Test is done to determine the amount of insulin being produced by the pancreas.
The C Peptide Test requires a blood sample, which is usually collected through a venipuncture.
