Catecholamine blood test

Norepinephrine - blood; Epinephrine - blood; Adrenalin - blood; Dopamine - blood

This test measures the levels of catecholamines in the blood. Catecholamines are hormones made by the adrenal glands. The three catecholamines are epinephrine (adrenalin), norepinephrine, and dopamine.

Catecholamines are more often measured with a urine test than with a blood test.

Blood test

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
