Overview of the Metanephrines (Plasma) Test
The Metanephrines (Plasma) test is a specialist endocrine blood investigation measuring plasma metanephrine-related markers associated with catecholamine metabolism.
Metanephrines are metabolites produced during the breakdown of catecholamine hormones.
Plasma Metanephrines testing is generally requested when a clinician is investigating excessive catecholamine production or another endocrine condition in which these biochemical pathways are relevant.
This is not a general wellness screening test.
Correct pre-analytical handling is particularly important.
The plasma specimen must be frozen within two hours of collection.
Testing must therefore be arranged through a collection pathway able to process the sample within the required timeframe.
The Metanephrines (Plasma) test costs £249.

Symptoms and Reasons to Consider the Metanephrines (Plasma) Test
Symptoms associated with catecholamine excess are non-specific and require specialist interpretation.
Episodes of marked palpitations - Endocrine causes are only one of several possibilities.
Episodic sweating or tremor - These symptoms can have many causes.
Recurrent headaches together with other compatible symptoms - Clinical assessment determines whether specialist testing is appropriate.
Difficult-to-control or episodic hypertension - Plasma Metanephrines may be requested in selected cases.
An adrenal finding on imaging - Biochemical investigation may be recommended.
A clinician has specifically requested Plasma Metanephrines - This remains the clearest indication.
Severe headache with very high blood pressure, chest pain, neurological symptoms or acute deterioration requires urgent clinical assessment.
Routine blood testing should not delay emergency care.

Understanding Your Results
Plasma Metanephrines should be interpreted by an appropriate clinician alongside symptoms, medication and the reason for testing.
