This blood test measures the amount of C-peptide, a substance that is released when the pancreas produces insulin. By understanding fasting C-peptide levels, healthcare professionals can gain valuable insights into beta-cell function, diagnose different types of diabetes, and investigate conditions like unexplained hypoglycemia.

What is C-Peptide and Why is it Measured?

C-peptide is a byproduct of insulin synthesisValues between 100 and 300 pmol/L indicate intermediate insulin secretion. Values less than 100 pmol/L indicate severe insulin deficiency and individuals should .... When proinsulin, a precursor to insulin, is cleaved in the pancreatic beta cells, it splits into insulin and C-peptide作者：T Ohkura·2013·被引用次数：100—20/(fasting C-peptide × fasting plasma glucose) is a simple and effective index ofinsulin resistancein patients with type 2 diabetes mellitus: .... Because the pancreas releases equimolar amounts of insulin and C-peptide, measuring C-peptide levels provides an accurate reflection of the body's endogenous insulin production. This is particularly important because administering exogenous insulin does not affect C-peptide levels; therefore, the presence of C-peptide indicates that the body is producing insulin itself. In contrast, if only exogenous insulin is administered, C-peptide will be absent.

The Role of Fasting in C-Peptide Testing

A crucial aspect of fasting C-peptide interpretation is the fasting state. Many C-peptide tests require patients to fast for eight to 12 hours, avoiding food and drink other than water. This standardized approach helps to establish a baseline measurement of insulin production when the body is not actively responding to food intake.C-Peptide, Insulin, Proinsulin and Interpretations A fasting C-peptide measurement provides a snapshot of the pancreas's baseline secretory capacityAs such, the presence ofC-peptideindicates endogenous production of insulin, whereasC-peptideis absent if only exogenous insulin is administered.

Interpreting C-Peptide Levels: What the Numbers Mean

The interpretation of fasting C-peptide results depends on the measured levels, which can vary based on units and laboratory reference rangesC-Peptide: Reference Range, Interpretation, Collection and .... However, general guidelines exist:

* Low C-peptide Levels: Low C-peptide levels, often indicated by a fasting C-peptide of less than 0.作者：E Maddaloni·2022·被引用次数：147—While lowC-peptideinvariably predicts insulin deficiency, which at mealtimes provokes marked postprandial hyperglycaemia, a low, but still measurableC-peptideindicates the persistence of residual endogenous insulin secretion, which restrains hepatic glucose production and controlsfastingplasma ...6 ng/ml, or a C-peptide value less than 100 pmol/L, suggest decreased insulin production or beta-cell failure. This is consistent with severe insulin deficiency and is a hallmark of type 1 diabetes.

Other Applications and Considerations

Beyond diabetes, C-peptide levels have been linked to other health outcomes. For instance, fasting serum C-peptide levels have been found to be significantly related to hazards of cardiovascular and overall death in non-diabetic adults and can serve as a better predictor of these outcomes.
