Copeptin is the stable surrogate marker of vasopressin (VP), which is released in response to elevated plasma osmolality or low blood pressure. Elevated plasma copeptin levels are associated with higher risk of insulin resistance-related disorders, such as type 2 diabetes (T2DM), metabolic syndrome (MS), and cardiovascular disease, and experimental reduction of circulating VP levels is shown

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

Please note that this is a NON-MEDICARE REBATABLE test. Today, the main use of copeptin is its role as stable surrogate marker for AVP concentrations in humans. 13 A prospective trial with 91 healthy volunteers undergoing a standardized test protocol with osmotic stimulation via hypertonic saline infusion and following osmotic suppression with oral and intravenous water load 23 showed a strong correlation between plasma AVP (when measured with a This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes. 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.

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).
