Why This Biomarker Matters

Abnormal CSF amino acid levels help diagnose rare inherited metabolic disorders affecting the nervous system. Early detection allows specialist doctors to manage these serious conditions.

Overview

3-Methylhistidine is an amino acid derivative found primarily in muscle protein. serum or plasma testing measures this compound in the fluid surrounding the brain and spinal cord. This is a specialized test used by metabolic specialists to diagnose rare genetic amino acid disorders affecting the nervous system. Results are interpreted by specialists in metabolic and neurological conditions.
