Description

A catecholamines test measures the levels of three hormones in the body: 

Epinephrine (adrenaline), Norepinephrine (noradrenaline), and Dopamine. 

These hormones are released by the adrenal glands in response to stress, fear, or physical exertion. 

Normal levels of catecholamines vary depending on the test method and the individual. High or low levels may indicate: 

• Pheochromocytoma: A rare tumor of the adrenal glands that produces excessive catecholamines. 
• Neuroblastoma: A type of childhood cancer that can also produce excessive catecholamines. 
• Stress: High levels of catecholamines can be a sign of chronic stress. 
• Heart failure: Low levels of catecholamines can be a sign of heart failure. 
• Adrenal insufficiency: A condition where the adrenal glands do not produce enough catecholamines.

Fasting not required.
