Why This Biomarker Matters

Elevated 3-HG may indicate rare metabolic disorders affecting amino acid metabolism. This helps diagnose genetic conditions causing neurological or developmental problems.

Overview

3-hydroxyglutarate (3-HG) is an organic acid produced during normal amino acid metabolism. Elevated blood levels may indicate rare metabolic disorders affecting glutamic acid metabolism or certain genetic conditions. This test helps identify inborn errors of metabolism that could cause neurological symptoms, developmental delays, or organ dysfunction. Abnormal accumulation of this compound interferes with normal cellular energy production and protein synthesis.
