Test Code:
098-10-0009

Order Name:
Catecholamines [Noradrenaline, Adrenaline, Dopamine] (U-24 hrs.)

 
 
Clinical Information:
The catecholamines adrenaline, noradrenaline, dopamine are synthesised from amino acid L-phenylalanine or L-3, 4-dihydroxyphenylalanine and play a central role in the organisms as hormones and neurotransmitters
 
Reference Value:
Test Reference Value Unit
Noradrenaline 0 - 97 microgram/24 h
Adrenaline 0 - 27 microgram/24 h
Dopamine 0 - 500 microgram/24 h
 
Interpretation:
Phaeochromocytoma and some other tumor of the nervous systems are characterized by a greatly enhanced production of catecholamine in repective tissue and resulting in increased circulation and excretion of catecholamines in urine
