<Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> High anion gap metabolic acidosis is a form of metabolic acidosis characterized by a high anion gap (a medical value based on the concentrations of ions in a patient's serum). An anion gap is usually considered to be high if it is over 12 mEq / L . </P> <P> High anion gap metabolic acidosis is caused generally by acid produced by the body, . More rarely, high anion gap metabolic acidosis may be caused by ingesting methanol or overdosing on aspirin . The Delta Ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present . </P> <P> The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap . </P>
