## In brief: Anion gap

The anion gap is a calculation in which you subtract the sum of the negative ions in the blood (chloride, bicarbonate) from the sum of the positive ions (sodium, potassium).

Often potassium is left out because it has only a very small effect. A normal gap is < 11. If the result of the subtraction is > 11 you have a high anion gap acidosis, which means some other acid is causing acidosis (ketoacids.
