Test Definition: CPAVP Copeptin proAVP, P Overview Useful For The investigation of the differential diagnosis of patients with water balance disorders, including diabetes insipidus, in conjunction with osmolality and hydration status May aid in the evaluation of cardiovascular disease in conjunction with other cardiac markers Method Name

Although the water deprivation test determined the correct diagnosis with 76.6% accuracy, the copeptin test had a 97% rate of correct diagnoses. The investigators said that this allowed patients to receive faster treatment. Of the 144 patients that underwent both tests, 62 patients had forms of diabetes insipidus and 82 patients had polydipsia.

However, it is technically cumbersome to administer, and the results are often inaccurate. The curre A single Copeptin measurement can immediately distinguish central diabetes insipidus from nephrogenic diabetes insipidus. As a consequence, Copeptin measurement reduces the burden of the water deprivation test for the majority of patients and improves patient management within the clinic. Ref-1. Smart Copeptin testing.

Test. Used to differentiate central DI, nephrogenic DI, and primary polydipsia. A baseline (without water deprivation or hypertonic saline-stimulation) copeptin level >21.4 picomol/L differentiates nephrogenic DI from primary polydipsia and central DI. Timper K, Fenske W, Kühn F, et al. Diagnostic accuracy of copeptin in the differential diagnosis of the polyuria-polydipsia syndrome: a Primary polydipsia was distinguished from partial central diabetes insipidus with the indirect water-deprivation test in 77 of 105 patients (73.3%), compared to 99 of 104 patients (95.2%) with the In the differential diagnosis of diabetes insipidus, after 8 hours water deprivation (fasting blood samole collection in the morning) Copeptin can be evaluated as follows: < 2.6 pmol/l: central diabetes insipidus totalis. 2,6 - 20 pmol/l: further Investigation needed (further information fig 3.) > 20 pmol/l: Nephrogenic diabetes insipidus 2018-08-01 2020-05-08 Copeptin levels of less than 2.5 pmol/L reliably identified diabetes insipidus after pituitary surgery, while levels of more than 30 pmol/L ruled out the condition, investigators reported online in the Journal of Clinical Endocrinology and Metabolism.

Of the 144 patients that underwent both tests, 62 patients had forms of diabetes insipidus and 82 patients had polydipsia. 2019-08-17 · Arginine-stimulated copeptin measurements are an innovative test for diabetes insipidus with high diagnostic accuracy, and could be a simplified, novel, and safe diagnostic approach to diabetes insipidus in clinical practice. 2018-08-16 · A hypertonic saline–stimulated plasma copeptin level lower than 6.5 pmol/L was 95% sensitive and 100% specific for central diabetes insipidus. This test's accuracy was superior to that of water-deprivation testing (with or without measurement of copeptin), and it distinguished between primary polydipsia and both partial and complete central diabetes insipidus.
