Biomarker Reference · Gly
Glycine (Gly) is a clinical biomarker used in neurological-mental-health assessment. Glycine is the simplest amino acid and an inhibitory neurotransmitter in the spinal cord and brainstem, modulating motor and sensory pathways. It is measured in 3 laboratory tests on BiomarkersLabs.com.
Glycine is the simplest amino acid and an inhibitory neurotransmitter in the spinal cord and brainstem, modulating motor and sensory pathways. It also serves as a co-agonist at NMDA receptors, supporting excitatory signalling. Urinary glycine reflects whole-body amino-acid metabolism, detoxification conjugation reactions, and dietary intake.
Urinary glycine is measured in functional neurology to explore inhibitory signalling and detoxification capacity. Low levels are interpreted as compromised conjugation or inadequate synthesis, though clinical significance is exploratory and not diagnostically validated.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
