Abstract

In metabolic acidosis, the concentrations of anions associated with intermediary metabolism are increased and can make a significant contribution to the observed acidosis. Here we describe a method for the rapid determination of the plasma ultrafiltrate profile of these anions using liquid chromatography coupled to electrospray ionisation mass spectrometry (LC/ESI-MS). The ultrafiltrate from patients with acidosis resulting from various causes were examined and the results compared to control values. Using the LC/ESI-MS method described, a unique plasma ultrafiltrate anion profile was obtained for each of the groups studied that provides rapid diagnosis of the type of underlying acidosis.
