The anion gap is a calculated measure. It is computed with a formula that uses the results of several individual lab tests, each of which measures the concentration of a specific anion or cation. The concentrations are expressed in units of milliequivalents / liter (mEq/L) or in millimoles/litre (mmol/L).
High anion gap metabolic acidosis. High anion gap metabolic acidosis is a form of metabolic acidosis characterized by a high anion gap (a medical value based on the concentrations of ions in a patient's serum). Metabolic acidosis occurs when the body produces too much acid, or when the kidneys are not removing enough acid from the body.
Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO 2 of 40 mmHg (5.3 kPa). [ 2] A base deficit (i.e., a negative base excess) can be correspondingly defined by the amount of strong base that must be added.
Adjunctive tests are useful in determining the aetiology of a raised anion gap metabolic acidosis including detection of an osmolar gap indicative of the presence of a toxic alcohol, measurement of serum ketones indicative of ketoacidosis and renal function tests and urinanalysis to detect renal dysfunction. Elevated protein (albumin, globulins ...
Normal anion gap acidosis. Other names. Non-anion gap acidosis. Specialty. Endocrinology, nephrology. Normal anion gap acidosis is an acidosis that is not accompanied by an abnormally increased anion gap . The most common cause of normal anion gap acidosis is diarrhea with a renal tubular acidosis being a distant second.
An anion-gap metabolic acidosis occurs later in the course of the overdose, especially if it is a moderate to severe overdose, due to the increase in protons (acidic contents) in the blood. The diagnosis of poisoning usually involves measurement of plasma salicylate, the active metabolite of aspirin, by automated spectrophotometric methods.
Hyperchloremic acidosis is a form of metabolic acidosis associated with a normal anion gap, a decrease in plasma bicarbonate concentration, and an increase in plasma chloride concentration [ 1] (see anion gap for a fuller explanation). Although plasma anion gap is normal, this condition is often associated with an increased urine anion gap, due ...
The urine anion gap is an 'artificial' and calculated measure that is representative of the unmeasured ions in urine. Usually the most important unmeasured ion in urine is NH 4+ since it is the most important form of acid excretion by the kidney. [ 5] Urine NH 4+ is difficult to measure directly, but its excretion is usually accompanied by the ...
