The Anion Gap calculates the difference between measured positive and negative ions in your blood, detecting unmeasured acids. It is a critical tool for diagnosing metabolic acidosis from diabetic ketoacidosis, lactic acidosis, kidney failure, or toxic ingestions. The anion gap must always be corrected for albumin to avoid missing a true high-gap acidosis.
Also known as: AG, Anion Gap, Anion gap (calculated), 阴离子间隙
A high anion gap means unmeasured acids are accumulating from diabetic ketoacidosis, lactic acidosis, kidney failure, or toxic ingestions. A low anion gap is rare.
Standard range is 8-12 mmol/L. The anion gap must be corrected for albumin.
