It is excreted in the urine and found in certain tissues. It is a marker for catecholamine-secreting tumors such as pheochromocytoma. Norepinephrine degradation. Normetanephrine is shown at ...
When plasma metanephrine levels were elevated to greater than 15% of the combined levels of normetanephrine and metanephrine, an adrenal tumor or a recurrence of an adrenal tumor that had already been excised can be predicted; Patients are more likely to present with the classic, paroxysmal (episodic) symptoms described above [70]

An article in the Journal of the American Medical Association, 2002, indicated that the measurement of plasma free levels of the metanephrines group of molecules (including metanephrine and normetanephrine) is the best tool in ...
Noradrenaline breakdown, with normetanephrine visible at upper left.. The metanephrines are a group of molecules consisting of metanephrine and normetanephrine.. An article in the Journal of the American Medical Association, 2002, indicated that the measurement of plasma free levels of metanephrines is the best tool in the diagnosis of pheochromocytoma, an adrenal medullary neoplasm.
High catecholamine levels in blood are associated with stress, which can be induced from psychological reactions or environmental stressors such as elevated sound levels, intense light, or low blood sugar levels. [10] Extremely high levels of catecholamines (also known as catecholamine toxicity) can occur in central nervous system trauma due to ...
