Metadrenalines (plasma)

The plasma free metadrenalines profile:

  • Metadrenaline
  • Normetadrenaline
  • 3-methoxytyramine
Plasma free metadrenalines are used for the diagnosis of catecholamine producing tumours including phaeochromocytoma or paraganglioma (PPGL). Patients with PPGL may present with episodes of hypertension with palpitations, severe headaches and sweating. Patients may be asymptomatic but have an incidentally discovered adrenal mass.
