According to a recent systematic review of ethylene glycol poisoning, mortality was unlikely to occur if the glycolate concentration was under what value?
Various studies have demonstrated that the anion gap is a good correlate for the glycolate concentration in the setting of ethylene glycol poisoning. In the cited reference, mortality was unlikely if the glycolate concentration was <8 mmol/L, which is correlated to an anion gap of 24 mmol/L.
