What are the benefits of C Peptide Test?

If you have diabetes, you would usually do or get your sugar level tested to check your blood sugar. Sometimes you may also get HbA1c test done every few months. These tests definitely give information about sugar level, but just getting them done does not provide complete information about health. Diabetes patients must get their C-Peptide test done once. Especially those whose sugar is not under control, medicines keep changing, still do not get relief.

What is C-Peptide test? About why it should be done Professor Dr. L.H. Ghotekar, Director, Department of Medicine, Lady Hardinge Hospital. Has told.

What is C-Peptide test?

Dr. Ghotekar tells that diabetes In patients with diabetes, either insulin is not produced or it is produced more or less as per the requirement. When the pancreas makes insulin, a protein is also made in the same process. It is called C-Peptide. C-Peptide test is done only to check the level of this protein in your blood.

Through this test the doctor understands how much insulin the pancreas is producing. If it is not producing it at all or is producing it more or less, then the type of diabetes can also be known accordingly. This also reveals whether there is a deficiency of insulin in the body or whether insulin resistance has occurred.

Why is C-Peptide important for diabetes patients?

The biggest advantage of this test is that type 1 and 2 diabetes can be detected. Understand it this way, if the level of C-Peptide in this test is very low then the pancreas is not producing insulin. That means the patient may have type-1 diabetes. At the same time, if C-Peptide is high then the body is producing insulin but it is not working properly.

This is a sign of type-2 diabetes. Through this test, it is also known whether the patient will be treated with medicines or whether he will have to take insulin now, because many patients keep taking tablets for a long time, while their pancreas has almost stopped producing insulin.
