Why This Biomarker Matters

Abnormal alanine excretion may indicate genetic metabolic disorders or muscle metabolism problems. Results help diagnose rare conditions affecting protein metabolism.

Understanding Your Results

Normal Range

0.5 – 6 nmol/mL

Overview

Alanine is an amino acid important for muscle metabolism, energy production, and immune function. A urine alanine test measures urinary excretion and may indicate amino acid metabolism disorders or specific medical conditions. Abnormal levels can suggest genetic metabolic disorders, liver disease, or muscle wasting. This specialized test is typically ordered when amino acid metabolism disorders are suspected, and results are interpreted alongside plasma amino acid levels and clinical symptoms.
