Copeptin refers to the C-terminal segment of the arginine vasopressin (AVP) prohormone remaining after enzymatic cleavage releases the active hormone mediating water homeostasis. As precursor and product exhibit equimolar release into circulation, quantifying stable it serves as a surrogate biomarker closely mirroring AVP levels.
