Copeptin, the C-terminal part of the prohormone of vasopressin (AVP), is released together with AVP in stoichiometric concentrations reflecting an individual's stress level.

Copeptin, which was described for the ﬁrst time by Holwerda in 1972, 1 is a glycosylated 39–amino acid long peptide with a leucine-rich core segment. AVP and copeptin share the same precursor peptide, the 164–amino acid long pre-provasopressin, which consists of a signal peptide, AVP, neurophysin II, and co-peptin.2 Thus, copeptin is the C-termi-

The assay recognizes human copeptin in serum, urine, cell culture supernates, and tissue homogenates. It provides a detection range of 78 pg/mL-5000 pg/mL. It has a high sensitivity, as low as 19.5 pg/mL.

Copeptin - The Copeptin test is used in the diagnosis of central diabetes insipidus and in the differential diagnosis of central or nephrogenic diabetes insipidus. It is a reliable surrogate marker for arginine vasopressin (AVP). Copeptin is an important new mid-region biomarker discovered in recent years.

18 Mar 2015 Abstract. Copeptin is a provasopressin-derived peptide, the precursor for arginine vasopressin (AVP), which is an antidiuretic hormone from the

Primary and secondary outcome measures: Copeptin, troponin, myoglobin and creatine kinase values. Clinical and paraclinical events. The final diagnosis was adjudicated blinded to copeptin result. Copeptin is also a marker of acute hemodynamic stress, and has been reported to aid in the prognosis or diagnosis of several cardiac disorders such as acute coronary syndrome, stable coronary artery disease, congestive heart failure, and acute ischemic stroke.

Methods . In patients with suspected stroke arriving within 4.5 hours of symptom-onset, copeptin-levels were measured in initial blood-samples.

Arginine vasopressin (AVP), also known as antidiuretic hormone (ADH), is a hypothalamic polypeptide that is transported along the axons of the synthesizing neurons into the posterior pituitary gland. Copeptin, the C-terminal segment of the arginine vasopressin prohormone, is an arginine vasopressin surrogate with high ex vivo stability that is easy to measure. 12,15,16 In previous studies, we Copeptin, a part of the original C-terminal of arginine vasopressin (AVP), is positively correlated with AVP in the normal population and patients with cardiopulmonary and vascular diseases, and is an acute endogenous stress marker. Its stability in vivo is stronger than AVP, and it is easy to measure. Note: Copeptin (also known as Copeptin proAVP or Copeptin AVP) and arginine vasopressin (AVP) are derived from the same precursor peptide. Copeptin has been proposed as a more stable, potentially superior, surrogate marker of AVP in the assessment of water balance disorders.

We sought to determine whether copeptin may be a useful biomarker to differentiate between ischemic stroke (IS), transient ischemic attack (TIA), and stroke-mimics.

Copeptin, the C-terminal part of the prohormone of vasopressin (AVP), is released together with AVP in stoichiometric concentrations reflecting an individual's stress level. Copeptin was found to be significantly increased in preeclamptic women with abnormal Doppler velocimetry when compared with preeclamptic women with normal Doppler velocimetry. 8 In a different study aimed at examining the effects of vaginal delivery versus cesarean delivery on copeptin levels in different groups of pregnant women, preeclamptic women were found to have greater copeptin when Human CPP (Copeptin) ELISA Kit from Assay Genie with a sensitivity of 18.75pg/mL and range of 31.25--2000pg/mL Context: Copeptin is the C-Terminal fragment of the arginine vasopressin (AVP) prohormone whose measurement is more robust than that of AVP. Similar release and clearance characteristics have been suggested promoting copeptin as a surrogate marker.
