What is C-peptide and Why is it Important?

C-peptide is a byproduct of insulin synthesis. When proinsulin is cleaved to form insulin, C-peptide is also produced. Therefore, measuring C-peptide levels in the blood or urine provides insight into how much insulin the pancreas is currently producing.作者：PM McKeigue·2019·被引用次数：79—Non-fasting random C-peptide levels in people with type 1 diabetesare highly correlated with C-peptide levels after a mixed meal [9].

Given the .... As a result, individuals with type 1 diabetes typically have very low or undetectable C-peptide levels, signifying severe insulin deficiency.

Normal C-peptide Levels and What They Mean

C-peptide Levels in Type 1 Diabetes

A defining characteristic of type 1 diabetes is the near-complete absence of endogenous insulin production. Consequently, C-peptide levels in individuals with type 1 diabetes are consequently very low or undetectable. Specifically, a C-peptide concentration of < 0.20 mmol/L is considered consistent with severe insulin deficiency, as seen in type 1 diabetes. In many cases, C-peptide levels may be so low that they are unmeasurable, often reported as less than 0.05-0.10 nmol/L, depending on the assay sensitivity. Some studies suggest that a plasma C-peptide cutoff of ≤0.20 mmol/L is indicative of T1D.

The decline in C-peptide levels in type 1 diabetes can be observed over time2025年11月11日—C-peptide < 0.20 mmol/L is consistent with severe insulin deficiency, as seen in type 1 diabetes.

Research indicates that C-peptide levels changed minimally between approximately 12 and 6 months before diagnosis, with a notable decline in the six months leading up to diagnosisC-Peptide Test: What It Is, Purpose, Procedure & Results. The natural history of type 1 diabetes often involves an initial exponential fall in C-peptide over a period, followed by a prolonged stabilization at very low levels. Studies have shown that among individuals with a duration of 1-5 years of the condition screened, approximately 48% had stimulated C-peptide above 0.2 nmol/l.

While type 1 diabetes is characterized by low or absent C-peptide, individuals with type 2 diabetes often have normal or even elevated C-peptide levels, especially in the early stages, as their pancreas is still producing insulin, albeit ineffectively. A C-peptide level of ≥0.Insulin C-peptide test30 mmol/L in the fasting or random state is often indicative of type 2 diabetes.

What Can Affect C-peptide Levels?

While C-peptide is a reliable indicator of insulin production, certain factors can influence its levels. For instance, prolonged diabetes can lead to a progressive decline in C-peptide. In some instances, even with a type 1 diabetes diagnosis, there might be detectable C-peptide, particularly early in the disease course or in subtypes like LADA (Latent Autoimmune Diabetes in Adults). These residual peptide levels can sometimes be associated with glycemic control. Non-fasting random C-peptide levels in people with type 1 diabetes are generally well-correlated with stimulated C-peptide levels after a mixed meal. Furthermore, certain treatments or medications might also impact C-peptide production or measurement... 1).Low levels of C-peptide may indicate a lack of endogenous insulin production. Genetic markers may also help distinguish type 1 from type 2 diabetes (2)..

Expert Insights and Research

Leading research in diabetes consistently highlights the significance of C-peptide as a biomarker. Studies have explored the predictive ability of C-peptide in distinguishing between diabetes types, with findings consistently showing significantly lower plasma C-peptide concentrations in type 1 diabetes compared to type 2 diabetes. The measurement of C-peptide also plays a role in understanding the natural history and progression of type 1 diabetes, with ongoing research into its decline phases and potential implications for therapeutic interventions. For example, studies on ustekinumab for type 1 diabetes in adolescents have shown associations with higher C-peptide AUC in the treatment group. Understanding peptide levels after diagnosis is also an area of interest, with cases reported of increased fasting and mixed-meal stimulated C-peptide levels even years after a type 1 diabetes diagnosis.
