Organic Acid Disorders

Organic acids are key metabolites of all pathways of intermediary metabolism Organic acid analysis provides information on physiological and pathophysiological status Performed on random urine samples Helpful in systemic intoxication or acute encephalopathy (newborns and infants) sub acute neurological disease or multisystemic manifestations (older children)

  • Metabolic acidosis
  • Increased anion gap
  • Cytopenia
  • Hypoglycemia
  • Hyperammonemia
  • Lactic acidemia
  • Ketosis
  • Developmental delay
  • Epilepsy

Urine: Collect a random urine without preservative in screw cap container. Keep frozen until shipment on dry ice.

Volume: 5-10ml

Methodology: GC-MS
