The Adrenaline (Epinephrine) - Plasma test measures the level of adrenaline, a hormone secreted by the adrenal glands, in your blood. Adrenaline plays a key role in the body's 'fight or flight' response to stress, affecting heart rate, blood pressure, and metabolism. Evaluating the level of adrenaline in your blood can help your healthcare provider diagnose conditions such as adrenal tumours and adrenal insufficiency, manage treatment strategies, and monitor your health over time.

An unusually high adrenaline level may indicate conditions like adrenal tumours, whereas low levels might suggest adrenal insufficiency. The test results can provide valuable information to guide diagnostic procedures, treatment plans, and ongoing health management. whereas low levels might suggest adrenal insufficiency. This test may be ordered when a healthcare provider suspects conditions associated with abnormal adrenaline production.

Preparations Required Avoid strenuous physical activities and the consumption of caffeine, alcohol, and certain medications like acetaminophen, antihistamines, and antidepressants prior to the test as they may affect the results.
