The anion gap measures the difference between negatively charged and positively charged electrolytes in the blood. A high anion gap indicates the blood is more acidic than normal, while a low anion gap means the blood is not acidic enough. It helps identify acid-base imbalances in the blood by comparing positive and negative electrolytes.

2. Anion gap:
Some electrolytes have a positive electric charge. Others have a negative electric charge. The
anion gap measures the difference—or gap—between the negatively charged and positively
charged electrolytes in your blood. If the anion gap is too high, your blood is more acidic than
normal. If the anion gap is too low, your blood isn't acidic enough
