Understanding C - Peptide, Post Parandial


What is C - Peptide, Post Parandial?

C-PEPTIDE, POST PRANDIAL test helps measure C-peptide level (connecting peptide) in the blood after a meal. This test helps distinguish between type 1 and type 2 diabetes, identify the cause of hypoglycemia, estimate insulin levels, and monitor the treatment of pancreatic tumors. This test may help your doctor know how much insulin your pancreas still makes if you have type 1 diabetes and when to start insulin if you have type 2 diabetes. You may get this test done when you have symptoms such as excessive thirst, frequent urination, and sores healing slowly, indicating diabetes. Measures such as losing extra weight, eating a balanced diet, and regularly monitoring blood sugar levels may help maintain optimal sugar levels in the body.

What is C - Peptide, Post Parandial used for?

The C Peptide test is performed when the patient gets a diabetes diagnosis to determine if sufficient insulin is being produced. It is also performed if anomalies in insulin production are determined, and if the patient blood sugar levels fall repeatedly.
