Connecting Peptide Insulin, Insulin C-Peptide, Proinsulin C-Peptide

The Purpose of a C-Peptide Test

It’s vital to know how much insulin your body is (or isn’t) producing if you have diabetes, hypoglycemia, or a pancreatic tumor. Insulin is necessary to control your body’s blood sugar levels and prevent symptoms such as arrhythmia, dizziness, impaired vision, and fatigue. This is when a C-peptide lab test can help you.

What Does the C-Peptide Lab Measure?

C-peptide is produced in conjunction with insulin and is easier to measure, making it a reliable barometer for tracking insulin levels.

Who Should Take a C-Peptide Test?

This test is often recommended for people who need a diagnosis of type 1 or type 2 diabetes or want to monitor the effectiveness of their diabetes treatment. It can also be used to help determine if someone has hypoglycemia or pancreatic cancer.

C-Peptide Testing Preparation

A 12-hour fast is required before testing. You must also avoid alcohol for 24 hours prior to the test day.

C-Peptide Blood Test Results

While there are some variations among labs, normal results generally range between 0.5 and 2.0 nanograms per milliliter. C-peptide levels below that range mean your insulin levels are insufficient. You may need further diabetes testing to further explore why your C-peptide labs are low.
