About This Test
Metanephrines and Normetanephrines are elevated in catecholamine secreting tumors like Pheochromocytomas and in tumors derived from neural crest cells like Paraganglioma and Neuroblastoma. Measurement of plasma free metanephrines appears to be the best test for excluding Pheochromocytoma as the tests sensitivity is approximately 96-99 % and offers specificity between 80-100 %. Tumoral production of 3-methoxytyramine is associated with presence of an underlying SDHB mutation and may be a biomarker of malignancy. Following patients with or without hypertension should be investigated for Pheochromocytoma: • Previous history of tumor • Adrenal incidentaloma • Hereditary predisposition

TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
