An anion gap value of 11.50 mmol/L is within the normal range, with normal anion gap values ranging from 8 to 16 (mean 12) mmol/L. An anion gap greater than 16 mmol/L suggests that the patient may have metabolic acidosis with increased organic acids, such as lactic acid, ketone bodies, and exogenous organic acids. In addition, renal insufficiency, severe hypocalcemia, and hypokalemia may also be manifested by an increased anion gap. An anion gap of less than 8 mmol/L suggests that hypoproteinemia may be present in the patient due to malnutrition, for example. In addition, severe hypercalcemia, hyperkalemia, etc. may also be manifested by a decrease in the anion gap. If the anion gap is not within the normal range, it is recommended to go to the hospital in time to identify the cause of the disease with the help of the doctor and take appropriate treatment.
