Catecholamines, Plasma

The Catecholamines, Plasma test measures the levels of adrenaline (epinephrine) and noradrenaline (norepinephrine) in the blood. These hormones are released by the adrenal glands and nerve cells in response to physical or emotional stress and help regulate heart rate, blood pressure, and the body’s “fight-or-flight” response. Measuring their levels can provide valuable information when investigating disorders involving the adrenal glands or the sympathetic nervous system, particularly conditions associated with excessive catecholamine production.

Who should get this test done?

This test may be recommended for individuals who:

●     Experience episodes of unexplained high blood pressure, rapid heartbeat, or excessive sweating.

●     Have symptoms suggestive of an adrenal gland disorder, such as pheochromocytoma or paraganglioma.

●     Experience recurrent headaches, palpitations, or anxiety-like episodes without a clear cause.

●     Require evaluation for disorders affecting catecholamine production or regulation.

●     Need further assessment based on abnormal imaging findings involving the adrenal glands.

Why consider this test?

The Catecholamines, Plasma test helps assess the body’s production of adrenaline and noradrenaline, two hormones that play a central role in the stress response. Abnormal secretion of these hormones can contribute to a variety of symptoms that may occur intermittently, making diagnosis challenging. By measuring both catecholamines together, the test provides valuable insight into adrenal and nervous system function and supports healthcare professionals in evaluating conditions associated with excessive hormone release.

More Information

Catecholamines are chemical messengers produced mainly by the adrenal glands and certain nerve cells. They help the body respond quickly to stressful situations by increasing heart rate, regulating blood pressure, and directing blood flow to vital organs and muscles. This test measures both adrenaline and noradrenaline, offering a broader assessment of catecholamine activity than measuring a single hormone alone. It is an important investigation for understanding the body’s hormonal response and evaluating disorders related to adrenal gland function.
