Clinical Indications

• Suspected inherited metabolic disorders
• Unexplained metabolic acidosis
• Recurrent vomiting or poor feeding
• Developmental delay or neurological symptoms
• Unusual urine findings or metabolic screening abnormalities
• Evaluation of suspected amino-acid/keto-acid metabolism disorders

Sample: Urine
Method: Qualitative chemical reaction
Report: Positive / Negative or as per laboratory protocol

Clinical Note:
A positive result is not diagnostic by itself. Further biochemical and molecular investigations may be recommended to identify the underlying metabolic disorder.
