Copeptin: A Novel Marker for Diagnosis and Prognosis of Various Diseases Associated With Diabetes

Abstract

Copeptin is an arginine vasopressin (AVP) precursor whose C-terminal has evolved into 39 amino acids. This AVP precursor is converted into equimolar amounts of Copeptin, neurophysin II, and AVP. a strong connection between the release of AVP and copeptin was observed. Measurement of AVP concentration remains complicated since AVP is an unstable peptide and additionally it is bound by platelets. Copeptin remains stable in serum or plasma for several days in a warm environment. and testing for copeptin yields findings in one h. Consequently, the quantity of copeptin might serve as a perfect replacement for reflecting the level of AVP. Copeptin has become identified as a beneficial measure in various diseases. The physiology and structure of copeptin, as well as its potential, to act as a predictive and diagnostic indicator of different diseases associated with diabetes is the goal of the current review.
