Anion Gap Calculator

 

Anion gap calculator calculates the difference in the measured cations and the measured anions in serum, plasma, or urine. Anion gap indicates disease conditions such as metabolic acidosis as in ketoacidosis in uncontrolled diabetes, in methanol or ethylene glycol poisoning, or in renal failure patients (high anion gap). A low anion gap is frequently caused by hypoalbuminemia. It is also caused by conditions such as increased serum potassium, calcium, or magnesium levels, or caused by medications or toxins such as lithium.

 

Anion Gap Calculator
Enter serum sodium Na+ (136-145 mEq/L): mEq/L
Enter serum chloride Cl-(98-107 mEq/L): mEq/L
Enter serum bicarbonate HCO3-(21-32 mEq/L): mEq/L

Anion gap = serum Na+ - (serum Cl- + serum HCO3-)

The normal anion gap = 10-14 mEq/L

A high anion gap indicates metabolic acidosis as in ketoacidosis in uncontrolled diabetes, in methanol or ethylene glycol poisoning, or in renal failure patients.

A low anion gap is frequently caused by hypoalbuminemia. It also caused by conditions such as increased serum potassium, calcium, or magnesium levels, or caused by medications or toxins such as lithium.
