An anion gap blood test is a way to check the levels of acid in your blood. The test is based on the results of another blood test called an electrolyte panel. Electrolytes are electrically charged minerals that help control the balance of chemicals in your body called acids and bases. Some of these minerals have a positive electric charge. Others have a negative electric charge. The anion gap is a measurement of the difference-or gap-between the negatively charged and positively charged electrolytes. If the anion gap is either too high or too low, it may be a sign of a disorder in your lungs, kidneys, or other organ systems. The anion gap blood test is used to show whether your blood has an imbalance of electrolytes or too much or not enough acid. Too much acid in the blood is called acidosis. If your blood does not have enough acid, you may have a condition called alkalosis. 1
In the OMOP vocabulary 8753 is a Standard Concept that represents the unit millimole per liter (mmol/L)

The literature indicates that a value less that 2 mmol/L is rare, but exists, while 24 mmol/L (also rare) indicates metabolic acidosis 2. The literature, combined with a data-driven approach to empirically establish possible low and high values, leads us to choose 0 and 25.
