WebJan 1, 2024 · A patient presenting late after a significant ingestion may have a normal osmolar gap and a high anion gap acidosis. The osmolar gap is more likely to be elevated in methanol ingestion than with ethylene glycol ingestions because of the lower molecular weight of methanol. Osmolar gaps of >100 have been reported. WebUrine anion gap is calculated by subtracting the urine concentration of chloride ( anions) from the concentrations of sodium plus potassium ( cations ): [3] = Na + + K + − Cl − where the concentrations are expressed in units of milliequivalents / liter (mEq/L). In contrast to the serum anion gap equation, the bicarbonate is excluded.
