Adrenalin®, Norepinephrine, Epinephrine, Dopamine, Noradrenaline
10 days
High-pressure liquid chromatography (HPLC) with electrochemical (EC) detection
Test Includes: Plasma catecholamines, fractionated (dopamine, epinephrine, norepinephrine)
Accredited Laboratory Partner
Contact Technical Support
Measures individual catecholamines (e.g., epinephrine, norepinephrine). Used to evaluate pheochromocytoma.
Plasma
1.5 ml
Lavender-top (EDTA) tube or green-top (heparin) tube
Patient should discontinue drugs and other substances that may affect measured catecholamine results for at least one week before obtaining the specimen
Draw blood in chilled lavender-top (EDTA) tube. Invert to mix with preservatives. Centrifuge and transfer the plasma to a labeled plastic transport tube. Place on-ice immediately (do not refrigerate) and freeze separated plasma within four hours of collection. Important: The patient should be in a fully recumbent position (lying down) for at least 20 minutes before and during sample collection. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
