Description
The catecholamines test measures the levels of three important hormones in your body:
- Epinephrine (adrenaline)
- Norepinephrine (noradrenaline)
- Dopamine
These hormones are produced by the adrenal glands and are released in response to stress, fear, or physical exertion.
Why the Catecholamines Test Is Important
Abnormal catecholamine levels—either high or low—can indicate several medical conditions, including:
- Pheochromocytoma: A rare adrenal gland tumor producing excessive catecholamines.
- Neuroblastoma: A childhood cancer that can increase catecholamine levels.
- Chronic Stress: Persistently high levels may indicate ongoing stress or anxiety.
- Heart Failure: Low levels can be a sign of decreased heart function.
- Adrenal Insufficiency: When adrenal glands do not produce enough catecholamines.
Monitoring catecholamine levels helps healthcare providers diagnose underlying conditions and guide appropriate treatment.
Fasting: Not required.
