7) Instead of vasopressin, researchers often measure copeptin as a proxy because it is more stable. The Swedish team did this in a subgroup of 13 ME/CFS patients and while copeptin levels were a bit low, they were still well within the reference values.

💡 Does arginine stimulate vasopressin via urea?

✅ Urea increased after arginine.
✅ Copeptin increased in healthy adults & primary polydipsia, but not in AVP deficiency.
❌ Urea & copeptin correlation? Weak.

Secondly: They measured vasopressin via immunoassay. This is an incredibly difficult technique. The vasopressin levels in the paper seem kinda low so I'm wondering if there was some measurement error

(this is why copeptin is now preferred)

Because vasopressin is hard to measure (it breaks down quickly), the team also checked copeptin in 13 patients.

Copeptin is a more stable molecule released alongside vasopressin.

Those levels were normal-range but mostly low-normal, reinforcing the low vasopressin finding.

No. Copeptin measures ADH activity. The way we do that in hyponatremia is via urine osm. Unless you are struggling with differentiating tea and toast syndrome (⬇️ ADH) from SIADH (⬆️ ADH) this will not help. The trouble in hyponatremia dx is separating CHF from SIADH which are both ⬆️ADH.
