Catecholamines

Catecholamines are a group of hormones produced primarily by the adrenal glands and are involved in the body’s response to stress. They include adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones help regulate heart rate, blood pressure, blood sugar levels, and other vital functions. When the adrenal glands release excessive or insufficient catecholamines, it can lead to serious health issues. High levels may indicate pheochromocytoma (a rare adrenal tumor), paraganglioma, severe stress, or heart failure. Low levels are less common but may point to adrenal insufficiency or certain neurological disorders.

The Catecholamines test may be recommended if there are symptoms such as unexplained high blood pressure, rapid heartbeat, sweating, headaches, or episodes of anxiety-like symptoms that could be linked to adrenal gland disorders. It is particularly useful in diagnosing pheochromocytoma (a rare adrenal gland tumor), neuroblastoma, and other catecholamine-secreting tumors. The test is not preferred for routine monitoring due to high biological variability. Plasma-free metanephrines are the preferred biomarkers for assessing treatment effectiveness for these conditions or evaluating adrenal gland function after surgery or during disease management.

Usually, no special preparation is required for this test. Eat and drink as per the daily routine. However, sharing the clinical history, current medications, and supplement use with the doctor before giving the sample is preferred, as these may influence the results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
