Anion Gap Blood Test
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.
