A few questions help us personalize your report.
C-Peptide is released in equal amounts with insulin from your pancreatic beta cells, making it a direct measure of endogenous insulin production. It distinguishes type 1 from type 2 diabetes and quantifies insulin resistance more accurately than insulin testing alone. C-Peptide remains measurable even in patients already taking exogenous insulin.
Also known as: C Peptide, C 肽, C-Peptid, C-Peptide, C-펩타이드, Connecting Peptide, C肽, Peptide C
High C-Peptide confirms insulin overproduction from insulin resistance or type 2 diabetes. Low C-Peptide indicates beta cell destruction in type 1 diabetes.
Standard range is 0.8-3.9 ng/mL. Functional practitioners target 1.0-2.0 ng/mL. C-Peptide above 2.5 ng/mL suggests significant insulin resistance.
