2025 #Understanding C-Peptide Reports: From Values to Curves, Decoding the Secrets of Pancreatic Function!# 🔍 What is C-Peptide? Why measure it? C-Peptide (Connecting Peptide) is a “byproduct” of insulin secretion from pancreatic β-cells, produced in equal amounts to insulin. However, it is more stable than insulin—it is not metabolized by the liver and is not … Read more
C-peptide is widely used in daily clinical diagnosis and treatment. So why do we need to test C-peptide? How is C-peptide tested? How do we interpret the results? What is C-Peptide? Why Test for C-Peptide? C-peptide, also known as connecting peptide, is a secretion product of pancreatic β-cells. It shares a common precursor with insulin—proinsulin. … Read more
