Efforts to enhance wellness and ameliorate disease via nutritional, chronobiological, and pharmacological interventions have markedly intensified interest in ketone body metabolism. The two ketone body redox partners, acetoacetate (AcAc) and D-β-hydroxybutyrate (βOHB) serve distinct metabolic and signaling roles in biological systems. A highly efficient, specific, and reliable approach to simultaneously quantify AcAc and D-βOHB in biological specimens is lacking, due to challenges of separating the structural isomers and enantiomers of βOHB, and to the chemical instability of AcAc. Here we present a single UPLC-MS/MS method that simultaneously quantifies both AcAc and βOHB using independent stable isotope internal standards for both ketones. This method incorporates one sample preparation step requiring only seven minutes of analysis per sample. The output is linear over three orders of magnitude, shows very low limits of detection and quantification, is highly specific, and shows favorable recovery yields from mammalian serum and tissue samples. Tandem MS discriminates D-βOHB from structural isomers 2- or 4-hydroxybutyrate as well as 3-hydroxyisobutyrate (3-HIB). Finally, a simple derivatization distinguishes D- and L-enantiomers of βOHB, 3-HIB, and 2-OHB, using the same rapid chromatographic platform. Together, this simple, efficient, reproducible, scalable, and all-encompassing method will support basic and clinical research laboratories interrogating ketone metabolism and redox biochemistry.
