Test Description
Catecholamines are a group of hormones produced by the adrenal glands, including epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine.
These hormones play vital roles as neurotransmitters and are involved in the body’s response to stress, regulating various physiological functions such as heart rate, blood pressure, and metabolism.
The measurement of catecholamine levels in blood or urine is essential for diagnosing specific conditions, particularly rare tumors such as:
- Pheochromocytoma: A tumor of the adrenal gland that secretes excess catecholamines, leading to symptoms like hypertension, palpitations, and sweating.
- Neuroblastoma: A cancerous tumor that develops from nerve tissue, primarily affecting children.
- Paraganglioma: A tumor that forms near the adrenal glands and can also cause elevated catecholamine levels.
Indications of the Catecholamines Test
The catecholamine test is typically ordered to:
- Diagnose conditions such as pheochromocytoma (a tumor of the adrenal gland that secretes catecholamines).
- Investigate unexplained hypertension.
- Evaluate symptoms like palpitations, sweating, or anxiety.
- Monitor treatment effectiveness for catecholamine-secreting tumors.
Patient Preparation/Instructions
Patients should follow these guidelines before the test:
- Avoid strenuous exercise for 24 hours prior to the test.
- Refrain from consuming caffeine and nicotine for at least 24 hours before testing.
- Discuss any medications with your healthcare provider, as some can affect catecholamine levels.
Typical Reference Values
Typical reference values for catecholamines vary by laboratory but generally are as follows:
- Epinephrine: 0–100 pg/mL
- Norepinephrine: 0–600 pg/mL
- Dopamine: 0–30 pg/mL
Turnaround Time
Results from a catecholamine test typically take about 1 to 3 days to process, depending on the laboratory.
