Methods used to determine the concentrations of some of the ions used to calculate the anion gap may be susceptible to very specific errors.
22.
Thus, the presence of a high anion gap should result in a search for conditions that lead to an excess of these anions.
23.
The " urine anion gap " is a different measure, principally used to determine whether the kidneys are capable of appropriately acidifying urine.
24.
The term " anion gap " usually implies " serum anion gap ", but the urine anion gap is also a clinically useful measure.
25.
The term " anion gap " usually implies " serum anion gap ", but the urine anion gap is also a clinically useful measure.
26.
The term " anion gap " usually implies " serum anion gap ", but the urine anion gap is also a clinically useful measure.
27.
Therefore, it is important to correct the calculated value of the anion gap for the concentration of albumin, particularly in critically ill patients.
28.
Other laboratory abnormalities may suggest poisoning, especially the presence of a metabolic acidosis, particularly if it is characterized by a large anion gap.
29.
The anion gap varies in response to changes in the concentrations of the above-mentioned serum components that contribute to the acid-base balance.
30.
The anion gap can be increased due to relatively low levels of cations other than sodium and potassium ( e . g . calcium or magnesium ).
