What is the C peptide?
C peptide or connecting peptide is a protein that is produced along with insulin in the pancreas. It is secreted into blood bloodstream in equal amounts with insulin. By measuring the level of C peptide it is possible to estimate how much insulin is produced by the body. C peptide is important in the assessment of the beta cell function of the pancreas. It is used to support the diagnosis of different types of diabetes and other disorders that are associated with insulin.
The information on C peptide levels is most valuable in the distinction between Type 1 and Type 2 diabetes and the investigation of insulin secretion in patients with hypoglycemia or insulin resistance.
How is the Test Performed?
The test is a simple blood test that involves the withdrawal of blood from the vein in the morning.
Preparation
- Overnight fasting of at least 8 to 10 hours is required for the test
- The doctor advises to avoid certain medications before the test
Collection
- The phlebotomist draws blood from the vein using a needle.
Laboratory Analysis
- The sample is analyzed in the laboratory using the technique ELISA or immunoassay.
What are the symptoms that prompt this test?
Your healthcare provider may suggest a C peptide test if you have some symptoms that are associated with disorders of insulin secretion or action. This test is employed to support the diagnosis of disorders like diabetes, insulinoma, and hypoglycemia. Following are some symptoms that may warrant this test:
Symptoms Exhibited in Children
- Low blood sugar without an unexplained reason
- Extreme irritability
- Lethargy
- Delay in development and growth
Symptoms Exhibited in Adults
- Extreme thirst or hunger
- Weight gain or loss without a known reason
- Urinating frequently
- Fatigue
- Difficulty managing the blood sugar level
- Sudden hypoglycemia symptoms
What are Normal Ranges for This Test?
The C peptide values may vary depending on the age, gender, and health condition of an individual. The generally accepted reference range is mentioned below;
- Adults – 3 to 3.3 ng/mL
- Children – 3 to 3.3 ng/mL
**The values given above are for general guidelines only. Always consult your healthcare provider for the correct interpretation of the results for early diagnosis and management of the disease. **
What Happens if Test Results Show Abnormal Levels?
High or low C peptide levels may be associated with several disorders of the insulin secretory process. Here is what the various results may mean:
Increased C Peptide Levels: The increase may be due to insulin secretion which may be caused by insulinoma, a tumor of the pancreas, or a condition known as insulin resistance which is seen in type 2 diabetes. It may also be a consequence of poor kidney function since the kidney is in charge of removing C peptide from the bloodstream.
Reduced C Peptide Levels: It means that there is inadequate insulin in the blood, which is a characteristic of Type 1 diabetes where the body’s own immune system attacks and destroys the insulin-producing cells in the pancreas. It can be associated with certain kinds of pancreatic dysfunctions or injuries. Sometimes, low C peptide levels may be seen in insulin-dependent diabetes.
If C peptide levels are abnormal then the doctor may advise for other tests like insulin tests, glucose tolerance tests, or imaging procedures to find out the cause.
