'''Blood:''' ''Metabolic Acidosis'', increased anion gap (as metabolic acidosis is due to increased organic acids rather than loss of bicarbonate<ref name="Ettinger"> Ettinger, S.J. and Feldman, E.C. '''Textbook of Veterinary Internal Medicine'''</ref>), decreased plasma bicarbonate concentration, decreased PCO2, decreased blood pH, ethylene glycol (in-house colorimetric kit),<ref name="BSAVA" />  although concurrent use of drugs such as diazepam and etomidate both of which contain propylene glycol can confound results<ref name="Ettinger" />. Hyperphosphataemia can be present in later stages due to acute renal failure <ref name="Ettinger" />, and hypocalcaemia as a consequence of this<ref name="Ettinger" /> and also as a consequence of ionised calcium binding to ethylene glycol metabolites.
