Catecholamines, Total

Optimal range: 242 - 1125 pg/mL

Catecholamines are a group of similar hormones released into the bloodstream in response to physical or emotional stress.

The primary catecholamines are:

Dopamine

Optimal range: 0 - 20 pg/mL

Dopamine is widely distributed throughout the central nervous system and is involved in the control of movement.

Epinephrine

Optimal range: 0 - 95 pg/mL

Epinephrine, often better known as adrenaline, is synthesized from norepinephrine in both the CNS and the adrenal medulla. Much like norepinephrine, this excitatory neurotransmitter helps regulate muscle contraction, heart rate, glycogen breakdown, blood pressure and more, and is heavily involved in a stress response. Elevated levels of epinephrine are often associated with hyperactivity, ADHD, anxiety, sleep issues, and low adrenal function. Over time, chronic stress and stimulation can deplete epinephrine stores leading to difficulty concentrating, fatigue, depression, insufficient cortisol production, chronic stress, poor recovery from illness, dizziness and more.

Norepinephrine

Optimal 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.
