Catecholamines are neurotransmitters and include dopamine, norepinephrine, and epinephrine. These proteins help control a variety of functions, including:
• muscle tone
• heart rate
• blood pressure
• glucose (sugar) metabolism

Catecholamines are primarily produced in your adrenal glands. Levels fluctuate in response to physical/emotional stress, outside temperature, blood loss, exercise, low blood sugar, and going from seated to standing, or vice versa

Includes: Dopamine, Epinephrine, Norepinephrine, Total Catecholamines (calculated)

Methodology: High Performance Liquid Chromatography (HPLC)

Limitations: Recent surgery, traumatic injury, upright posture, cold, anxiety, pain, clonidine withdrawal, and concurrent acute or chronic illness may produce elevated results.
