Neurotransmitters

Biomarkers included in this panel:

3,4-Dihydroxyphenylacetic acid (DOPAC)

Dopac (aka 3,4-Dihydroxyphenylacetic acid) is a metabolite of the neurotransmitter dopamine. Dopamine serves as the reward and pleasure center in the brain. DOPAC and HVA (Homovanillic Acid) are dopamine metabolites. DOPAC levels, when v

5-HIAA

5-HIAA is the primary metabolite of serotonin, a chemical substance (neurotransmitter) that transmits messages between nerve cells. After it is used by the body, serotonin is broken down in the liver, and its metabolites, including 5-HIAA, are e

Dopamine

Dopamine is a chemical found naturally in the human body. It is a neurotransmitter, meaning it sends signals from the body to the brain. Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The righ

Epinephrine

Epinephrine is commonly known as adrenaline. Your body naturally produces it during times of stress. The hormone is also necessary for maintaining a healthy cardiovascular system — it makes the heart beat more strongly, and diver

Gamma-aminobutyric acid (GABA)

GABA stands for Gamma-aminobutyric acid (γ-Aminobutyric Acid) and is a nonessential protein amino acid. GABA is an inhibitory neurotransmitter in the central nervous system.

Glutamate

Glutamate functions as the major excitatory neurotransmitter and metabolic fuel throughout the body. Glutamate is produced in your body, and is also found in many foods.

Glycine

Glycine plays an important role in the body’s ability to detoxify itself as well as in wound healing. It is also important in the creation of nucleic acids and bile acids.

Metanephrine (24hr Urine)

This test measures the amount of metanephrines in your urine that your body makes over a 24-hour period. Metanephrines are made when your body breaks down hormones called catecholamines. These hormones are made by the adrenal glands. Catechol

Metanephrines, Total (24hr Urine)

Metanephrines are made when your body breaks down hormones called catecholamines. These hormones are made by the adrenal glands. Catecholamines help your body respond to stress. They are sometimes called "fight or flight" hormones. They als

Norepinephrine

Norepinephrine, also known as noradrenaline, is important for mental focus and emotional stability. Norepinephrine functions as a neurotransmitter and hormone that regulates the “fight or flight” response and elevates blood pressure an

Normetanephrine

Normetanephrine, a metabolite of norepinephrine, is at normally low levels in the plasma. Certain tumors increase the levels and will increase the levels of nor-metanephrine. The Normetanephrine test, when normal, means these tumors are not present.

Normetanephrine (24hr Urine)

Metanephrine and normetanephrine are breakdown products (metabolites) of the catecholamines epinephrine (adrenaline) and norepinephrine. This test measures the amounts of metanephrine and normetanephrine that are released into the urine over a 24-hou

PEA

PEA stands for Beta-phenylethylamine and is an excitatory neurotransmitter made from phenylalanine and it modulates neuron voltage potentials to favor glutamate activity and neurotransmitter firing.

Serotonin

Serotonin plays important roles in the resolution of mood, sleep, and appetite. Serotonin is an inhibitory neurotransmitter synthesized by enzymes that act on tryptophan and/or 5-HTP. Neurotransmitters are divided

Taurine

Taurine important for proper heart function, healthy sleep and promoting calmness. Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large
