Test Information
​Except when a controlled fasting test is performed, patients suspected of having an inborn error of metabolism should not fast beyond their regular schedule due to the possibility of developing symptoms of fasting intolerance and acute metabolic decompensation. Recommend drawing the specimen just prior to a routine feeding.
Reference Range Information
Interpretive report
Interpretation
​Fatty acid oxidation disorders are recognized on the basis of disease-specific metabolite patterns that are correlated to the results of other investigations in plasma (carnitine, acylcarnitines) and urine (organic acids, acylglycines).
