Also known as: Insulin C-Peptide
What is it? C-peptide is a byproduct created when insulin is produced. The C-peptide test monitors levels of C-peptide in the blood to determine how much insulin is produced by the beta cells of the pancreas. It can also help determine the cause of hypoglycemia.
Why is this test performed? The test is performed on people with diabetes to determine how much insulin is still being produced by the pancreas. Since the C-peptide test can be used to monitor beta cell productivity over time, it can help your doctor determine when to begin insulin treatment. If a person experiences recurring symptoms of hypoglycemia, a C-peptide test may be ordered to diagnose the cause of the hypoglycemia and to monitor its treatment.
How is this test performed? The test consists of a blood draw, usually from inside the elbow or from the back of the hand. You may need to fast for 8 to 10 hours before taking the test.
What do my results mean? The normal range for C-peptide levels is 0.5 to 2.0 ng/mL. This range can vary so you should speak with your doctor about your specific results.
What do abnormal results mean? High levels of C-peptide indicate high levels of insulin in the body due to excessive insulin production. Excessive insulin production is a result of high levels of blood glucose caused by glucose intake or insulin resistance. Low levels of C-peptide (or no C-peptide at all) indicate that your pancreas is producing little to no insulin.

Gone are the days of repelling Mission Impossible-like from the hospital ceiling to retrieve Charlie's medical files before the CDE entered our exam room. It's not that I don't care anymore about his A1c. Of course I care. Maybe in the past I was more consumed by it. For a very long time I so desperately wanted to see an A1c below 8. Now that we've been comfortably in the low to mid-7s for the last couple of years, there's just an expectation. It's become a little anticlimactic....
