title: Copeptin (CTproAVP), a new tool for understanding the role of vasopressin in pathophysiology
abstract: Arginine vasopressin (AVP) plays a key role in many physiologic and pathologic processes. The most important stimulus for AVP release is a change in plasma osmolality. AVP is also involved in the response and adaptation to stress. Reliable measurement of AVP is hindered by several factors. Over 90% of AVP is tightly bound to platelets, and its estimation is influenced by the number of platelets, incomplete removal of platelets or pre-analytical processing steps.
