From Healthmatters.io Team
These are the reference ranges for C-Peptide, Ultrasensitive:
Adults 8:00 a.m. fasting: 0.4 - 2.1 ng/mL
2 Hours Post Prandial (Sustacal): 1.2 - 3.4 ng/mL
2 Hours Post Glucose: 2.0 - 4.5 ng/mL
This test measures the level of C-peptide. Measuring C-peptide is an accurate way to find out how much insulin your body is making.
Insulin is a hormone that your pancreas makes. It helps blood glucose (blood sugar) get into your cells, where it can be used for energy. This helps keep your blood glucose at healthy levels.
During the process of making insulin, your pancreas produces C-peptide. C-peptide and insulin enter your bloodstream at the same time and in equal amounts. C-peptide doesn't affect your blood glucose levels, but it stays in your blood longer than insulin, so it's easier to measure accurately.
A C-peptide test can provide important information to help understand, monitor, and/or treat disorders that involve how well your body makes insulin, such as hypoglycemia (low blood sugar) and diabetes.

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
