Useful For
Diagnosis of inborn errors of metabolism
Highlights
This test provides a qualitative report of abnormal levels of organic acids identified via gas chromatography mass spectrometry.
Diagnostic specificity of inborn errors of metabolism via urine organic acids analysis is variable due to factors such as specimen collection when the patient is asymptomatic versus acutely ill, taking dietary supplements, or anabolic versus catabolic status of the patient.
