Osmosis video - Plasma anion gap

The plasma anion gap is the difference between the plasma concentration of Na+ sodium and the sum of plasma concentrations of (Cl �� + HCO3 ��) and represents the unmeasured anions in the plasma. The normal range of plasma anion gap is between 3 �11 mEq/L. It is elevated in organic acid metabolic acidosis, such as lactic acidosis and diabetes ketoacidosis. Its decrease can be seen in cases of metabolic alkalosis, meaning that the body is producing too little acid or eliminating too much acid.
