Certain newer markers for vasopressin have been identified. Copeptin is currently being studied as a novel biomarker.

- Enzymatic cleavage of vasopressin yields Copeptin and neurophysin. Copeptin is more stable, hence easily measurable. It has found to be increased in patients with hypo or hypervolemic hypernatremia as opposed to SIADH. Two additional markers, apelin and MR-proANP (midregional proatrial natriuretic peptide) are being studied. The true diagnostic potential of these parameters is still being studied.
