Neurotransmitters
What is a neurotransmitter test?
A neurotransmitter test measures the chemical messengers in the nervous system
that regulate communication between nerve cells. These tests help identify
whether levels are balanced, overactive, or deficient—factors that can
influence mood, sleep, focus, and overall neurological function.
What does it measure?
Comprehensive panels, such as those from ZRT Laboratory, assess 14 key
neurotransmitters and their metabolites, including:
- Serotonin
- Dopamine
- GABA
- Glutamate
- Norepinephrine
- Histamine
By measuring both parent neurotransmitters and downstream metabolites, the
test provides a complete picture of systemic patterns and avoids
misinterpretation that could occur when looking at single markers alone.
Who is it most suitable for?
This test is most suitable for individuals experiencing symptoms such as:
- Anxiety
- Depression
- Chronic fatigue
- Impulsivity (ADD/ADHD/OCD)
- Insomnia
- Severe PMS/PMDD
It may also benefit those with neurological or psychological concerns
influenced by genetics, environment, nutritional deficiencies, or heavy metal
exposure.
Clinical Use
Clinically, neurotransmitter testing is valuable for identifying the root
causes of mental health and neurological symptoms. It helps guide targeted
treatment plans, especially when combined with hormone and element testing,
which enhances accuracy by considering the complex interplay between
neurotransmitters, hormones, and brain health. The at-home dried urine method
makes testing accessible and reliable, supporting precision-based
interventions while reducing trial-and-error in treatment.
