Which is the normal anion gap range?

Explanation:
Anion gap helps classify metabolic disturbances by comparing the measured ions in the blood. It’s calculated as Na minus (Cl plus HCO3), and when potassium isn’t included, the normal range is about 8 to 12 mEq/L. This is the standard reference used in NBRC questions. So, the range 8–12 mEq/L best fits the normal value. If potassium were included in the calculation, the normal range would be closer to 12–16, but NBRC typically uses the 8–12 range. A value outside this range suggests an abnormal acid-base state, with high values indicating high anion gap metabolic acidosis from excess unmeasured anions.
