Test: Organic Acids, Screen
Comments:We utilize the same gas chromatography-mass spectrometric technique as in our comprehensive organic acid analysis, but limit the analysis to a strategically selected group of compounds which should permit identification of patients with nearly all known organic acidemias. There are a limited number of known conditions which this screen will not detect, and complete diagnosis may require subsequent comprehensive analysis.
Specimen type:Urine
Sample Requirements:Urine, 10-20 mL (minimum 5 mL), frozen without preservatives and shipped frozen (packed with dry ice).
