Sample Report 


  • Epinephrine
  • Norepinephrine
  • Dopamine

The adrenal glands make large amounts of catecholamines as a reaction to stress. Catecholamines help the body respond to stress or fright and prepare the body for "fight-or-flight" reactions.

The main catecholamines are epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine, which are all measured in this test.

Catecholamines increase heart rate (palpitations), blood pressure, breathing rate, muscle strength, and mental alertness. They also lower the amount of blood going to the skin and increase blood going to the major organs, such as the brain, heart, and kidneys.

Certain rare tumors of the adrenal glands can also increase the amount of catecholamines in the blood and urine.

Fasting for four or more hours without smoking is required for this test. Walnuts and bananas should be avoided for a week prior to the blood test. Take all medications as prescribed.
