C-Peptide
C-Peptide is a clinical biomarker on the Pancreas panel, reported in ng/mL. Standard reference range: 0.8–3.85 ng/mL. Functional (optimal) range used by integrative practitioners: 1.2–2.5 ng/mL.
What is C-Peptide?
C-peptide is co-secreted with insulin in equimolar amounts from pancreatic beta cells but is not extracted by the liver, making it a more reliable marker of endogenous insulin production than insulin itself.
Reference ranges
| Range type | Value (ng/mL) | Source |
|---|---|---|
| Standard (lab) | 0.8–3.85 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 1.2–2.5 | Integrative / functional medicine consensus |
How SomaVue interprets C-Peptide
SomaVue maps every result for C-Peptide against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
