A healthy result should fall into the range 217 - 1109 pg/mL.

Norepinephrine (also called noradrenaline) is one of the catecholamines. Catecholamines are hormones made by the adrenal glands. The three catecholamines are epinephrine (adrenalin), norepinephrine, and dopamine.

Norepinephrine is a naturally occurring chemical in the body that acts as both a stress hormone and neurotransmitter (a substance that sends signals between nerve cells).

It’s released into the blood as a stress hormone when the brain perceives that a stressful event has occurred.

As part of the body’s response to stress, norepinephrine affects the way the brain pays attention and responds to events. It can also do the following:

  • increase blood sugar levels
  • increase heart rate
  • increase contractility

Norepinephrine can also cause your blood vessels to narrow, which increases blood pressure.

Normal ranges:

The normal range for norepinephrine is 217 – 1109 pg/mL.
