We have developed a method for the fractionation of short-chain acylcarnitines (C4, C5, C5OH) to assist in the differential diagnosis of branched-chain organic acidurias. The assay is performed on Acquity UPLC coupled with Premier tandem mass spectrometer operated in SRM mode. We have evaluated samples (blood spots, urine, plasma) from patients with several branched-chain organic acidurias and compared them to normal controls to validate this method.
