Detailed Information

Analysis of urinary neuro-biogenic amines (neurotransmitters), and their metabolites, provides a non-invasive assessment of neurotransmitter metabolism. Neurotransmitter testing may provide therapeutic opportunities that improve clinical success and patient health outcomes.

A review of the current scientific literature demonstrates how urinary neuro-biogenic amine testing may be used in clinical practice:

  • Functional testing - Neuro-biogenic amine metabolism may be mediated by a variety of enzymes, including catechol-O-methyltransferase (COMT) and monoamine oxidase (MAO).  Patterns of neurotransmitters and their metabolites may provide functional information about these two important enzymes.
  • Identify imbalances - research indicates that urinary neuro-biogenic amine measurements may correlate with neurological conditions such as depression and PTSD.
  • Response to therapy - certain neuro-biogenic amines, such as serotonin, may be altered by the addition of neurotransmitter precursors such as 5-hydroxytryptophan (5-HTP).  These changes may be apparent in the urine.
  • Risk assessment - Changes in urinary serotonin, dopamine, and glutamate levels have been suggested as biomarkers for neurobehavioral toxicology (symptoms from chemical or toxicant element environmental exposures)

Neurotransmitters, or "biogenic amines" are secreted from pre-synaptic neurons into the synapse between nerve cells to stimulate receptors on post-synaptic neurons. The neurotransmitters are all produced from essential aromatic amino acids.  Neurotransmitter metabolism may be mediated by a variety of enzymes expressed differently throughout the body.  Circulating levels of neurotransmitters and metabolites may have distinctive sources.  Urinary levels of neuro-biogenic amines primarily reflect the activity of the peripheral and GIT enteric nervous systems.  Up to 20% of urinary neurotransmitter metabolites are estimated to originate in the CNS.

A lack of nutritional cofactors (vitamins, minerals) required for normal enzyme function may decrease enzyme function and neurotransmitter levels.  Neurotransmitter receptors and metabolic enzymes may be subject to mutations and single nucleotide polymorphisms (SNPs) that may affect receptor or enzyme function.  Normal neurotransmitter receptor function is also necessary for normal neurotransmitter activity.  Neurotransmitter levels may be influenced by diet, lifestyle and other health conditions such as: high sodium intake, age, gender, body mass index, kidney function, environmental exposures, infection and tobacco use.

Urinary neuro-biogenic amines provide an overall assessment of a patient's ability to synthesize and metabolize neurotransmitters, which must occur in both the peripheral nervous system and behind the blood brain barrier (BBB).  Alterations in urinary neurotransmitter status may result from a variety of conditions including metabolic disorders, mood/behavioral disorders, environmental exposures or (rarely) the presence of certain tumors.  Evaluation of neurotransmitters may provide increased clarity about a patient's health and functional status.

Urinary neuro-biogenic amines are a non-invasive way to assess the synthesis and metabolism of neurotransmitter molecules essential for normal function.  Information gained through neurotransmitter testing may provide therapeutic opportunities that improve clinical success and patient health outcomes.  Associations between urinary neurotransmitter levels and health conditions have been documented in scientific literature and may provide valuable insight as part of a comprehensive health assessment.

Collection Instructions:

Urine Collection

1. When you wake up and get out of bed for the day, you can collect either the 1st morning void of the day, or if doing a Neurotransmitter test, you have the option of collecting a 2nd morning void.

In the Collection Information Section of the Requisition fill in the waking time and the time that the urine was collected. Mark the collection type box: 1st or 2nd morning.

2. Collect a midstream specimen of urine in the collection cup. DO NOT urinate directly into the tube. The tube contains an acid preservative* that may irritate the skin.
3. Pour the urine into the specimen vial. Fill the vial to the fill line – do not underfill. Close vial tightly to ensure a good seal. Gently rock the tube back and forth to mix urine with the preservative.*
4. Complete the requested information on the tube label: name, date of birth, date and time of collection.
5. Place the tube inside the plastic zip-lock bag with the absorbent material and seal.
6. Freeze the urine sample for at least 4-6 hours and keep frozen with the frozen ice pack until ready to ship.

*Please note: specimen vial contains approximately 60mg of oxalic acid. Do not ingest or inhale. Wipe spills with a wet towel. In case of contact with skin, wash with soap and plenty of water. In case of accidental contact to eye or accidental contact to eye or ingestion, rinse with plenty of water. Seek medical attention if warranted.
