Description complémentaire du produit

C-Peptide Test Kit (CLIA Method) is an in vitro diagnostic test designed to quantitatively determine the C-peptide in human serum and plasma. Clinically, it is intended for professional use as an aid in the diagnosis of patients with abnormal insulin secretion. C-peptide is a single-chain polypeptide composed of 31 amino acids (AA 33-63), with a molecular weight of approximately 3021 Da. It is secreted by pancreatic β cells and cleaved from proinsulin. Numerous studies have confirmed that C-peptide levels directly reflect pancreatic β cell function and aid in disease classification in diabetic patients. In the early stages of diabetes, whether it is type 1 or type 2 diabetes, both insulin and C-peptide levels can reflect β cell function. However, due to limited cellular uptake of C-peptide from peripheral blood, the concentration of C-peptide in peripheral blood closely resembles the initial secretion by β cells. Its clearance rate is relatively stable and is not significantly affected by other influencing factors. Therefore, the C-peptide release curve is superior to the insulin release curve, providing a better reflection of pancreatic β cell function. Moreover, C-peptide does not cross-react with exogenous insulin, and even insulin antibodies do not affect C-peptide levels. Thus, the measurement of C-peptide in the blood serves as a crucial indicator for monitoring pancreatic β cell secretion function, especially in diabetic patients treated with exogenous insulin. In clinical practice, it is primarily used to assess pancreatic islet function.
