Copeptin is stored in the neurohypophyseal vesicles together with AVP and neurophysin II until they are secreted (4). Schematic presentation of copeptin generation and maturation is shown in Figure 1. Copeptin also has a very important role in the proteolysis of pre-proAVP, but its main role in the circulation is still unknown (3,6). Quest test code 37740, C-Terminal pro-vasopressin, CT-proAVP, ADH, Antidiuretic hormone. COPEP. Clinical significance: The Copeptin test is used in the diagnosis of central diabetes insipidus and in the differential diagnosis of central or nephrogenic diabetes insipidus.

Although the water-deprivation test is considered the reference standard for the evaluation of DI, measurement of saline stimulated copeptin was shown to be more accurate than the water-deprivation test.(2) In this indirect water deprivation test with a cutoff of 4.9 pmol/L or less indicated central DI while a concentration greater than 4.9 pmol/L indicated primary polydipsia. Copeptin proAVP is an improved replacement for AVP testing that is useful as part of differential diagnosis of patients with water balance disorders, including diabetes insipidus (DI) and primary polydipsia, in conjunction with osmolality and hydration status. The Brahms CT-proAVP assay measures the C-terminal precursor fragment of arginine vasopressin (AVP), otherwise known as copeptin. Copeptin is released on an equimolar basis with AVP and therefore measurement of serum/plasma copeptin provides a surrogate measure of AVP concentrations. The clinical value of measuring serum/plasma copeptin is in the differential diagnosis of polyuria/polydipsia syndromes.

Test Location ON, CA Plasma AVP and copeptin will be measured at baseline (8 am before start of thirsting), and hourly during the water deprivation test. Study hypothesis: Copeptin levels will provide a better diagnostic accuracy in the diagnosis and differential diagnosis of diabetes insipidus as compared to AVP measurement. Pediatric Copeptin Reference Intervals: Non-water deprived pediatric subjects: Copeptin reference interval <14.5 pmol/L As suggested by a small study involving 15 children with polyuria and polydipsia from Tuli G et al, Clin Endocrinol (Oxf) 2018; 88(6):873-879: Following a water deprivation test: copeptin >20 pmol/L: nephrogenic diabetes insipidus test, with the perfect ROC, has an AUC = 1.0, whereas an uninformative test has an AUC = 0.5. The AUC can be interpreted as an average true positive fraction (proportion of test positives among the true positives).

Although the water-deprivation test is considered the reference standard for the evaluation of DI, measurement of saline stimulated copeptin was shown to be more accurate than the water-deprivation test.(2) In this indirect water deprivation test with a cutoff of 4.9 pmol/L or less indicated central DI while a concentration greater than 4.9 pmol/L indicated primary polydipsia. Copeptin and urea could not differentiate hypernatraemia induced by DH from that induced by SO (P = 0.66 and P = 0.30, respectively). Copeptin and urea reliably identify patients with CDI and are therefore helpful tools for therapeutic management in patients with severe hypernatraemia. Copeptin (Human) - EIA Kit, extraction-free. Quantity: Order *Phoenix Pharmaceuticals, Inc. cannot ship or deliver this product to addresses in the following The hypothesis suggested in the first study on the diagnostic value of copeptin for ACS, could be that endogenous stress caused by UA could be lower than in patients with AMI and could be insufficient to cause a copeptin release. 9 Moreover, the authors of the ROMICAT study, regarding their results, as they corroborated Kelly et al, 36 suggest that copeptin is a reflection of left ventricular Although the water-deprivation test is considered the reference standard for the evaluation of DI, measurement of saline stimulated copeptin was shown to be more accurate than the water-deprivation test.(2) In this indirect water deprivation test with a cutoff of 4.9 pmol/L or less indicated central DI while a concentration greater than 4.9 pmol/L indicated primary polydipsia.
