Why This Biomarker Matters

GABA dysfunction is linked to seizures, anxiety, and certain neurological disorders. This test helps evaluate nervous system health and guide treatment decisions for neurological conditions.

Overview

Gamma-aminobutyric acid (GABA) is a neurotransmitter that helps regulate nervous system activity. This urine test measures GABA levels adjusted for creatinine to account for urine concentration. GABA abnormalities may be associated with neurological conditions, seizure disorders, or metabolic imbalances. Testing GABA in urine can help evaluate neurological health and assess certain brain-related conditions, though interpretation requires clinical context.
