Abstract
One mode of a method for analyzing acylcarnitine according to the present invention is a method for analyzing C5 acylcarnitine using a tandem mass spectrometer, the method including: a measurement step of performing MRM measurement on a specimen according to at least one of MRM transitions of m/z 246>187, m/z 246>57, m/z 246>41, and m/z 246>29; and a processing step of distinguishing between isovalerylcarnitine and pivaloylcarnitine which is an isomer of isovalerylcarnitine in the specimen or determining whether or not C5 acylcarnitine in the specimen includes pivaloylcarnitine, using a measurement result obtained in the measurement step. This makes it possible to satisfactorily distinguish between isovalerylcarnitine and pivaloylcarnitine, which have been conventionally difficult to distinguish.
