    • Lactate gap: a diagnostic support in severe metabolic acidosis of unknown origin 

      Hauvik, Linn Eva; Varghese, Mercy; Nielsen, Erik Waage (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-24)
      Ethylene glycol poisoning is a medical emergency. The metabolites glycolate and glyoxylate give metabolic acidosis. Because of similar structure, these metabolites are misinterpreted as lactate by many point-of-care blood gas analyzers. The falsely high lactate values can lead to misdiagnosis, inappropriate laparotomies, and delayed antidotal therapy. As laboratory analyzers measure plasma lactate ...
