A 52-year-old female is admitted to intensive care unit (ICU) after being found on her floor's home, she presents decreased level of consciousness. Her blood profile performed at admission shows a severe metabolic acidosis with pH <7 and lactic acid >20_mmol/L. Crystals of calcium oxalate monohydrate are observed in the urine sediment. Osmolal gap is determined (88 mOsm/kg), so that treatment with intravenous ethanol and hemodialysis is initiated. Sample is sent to an outside laboratory to determinate levels of methanol, ethylene glycol and salicylates; ethylene glycol was positive with 2,68 g/L.
