Test Overview
Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS)
The analysis of acylcarnitine profiles is performed for use in screening of inborn errors of metabolism, specifically fatty acid oxidation disorders, and certain organic acidemias (acidurias). In some cases, results are diagnostic of a specific disorder, while in other cases, further testing may be needed.
