Elevations of C14:1 and C14:2 Plasma Acylcarnitines in Fasted Children: AÂ Diagnostic Dilemma

Elevations of plasma C14:1 and C14:2 acylcarnitines appear to be a physiologic result of lipolysis that occurs with fasting. Both metabolomics analysis and/or C14:1/C12:1 may distinguish C14:1 elevations from physiologic fasting-induced lipolysis vs VLCAD deficiency.
