1 COPEPTIN AS DIAGNOSTIC TOOL IN THE POLYURIA POLYDIPSIA SYNDROME: We have recently shown that copeptin, without prior water deprivation, identifies patients with nephrogenic diabetes insipidus. Water arginine vasopressin Homo sapiens
2 On the other hand, for the more difficult differentiation between central diabetes insipidus and primary polydipsia, a copeptin level of 4.9 pmol/L stimulated with hypertonic saline infusion differentiates between these two entities with a high diagnostic accuracy, and is superior to the water deprivation test. Water arginine vasopressin Homo sapiens
