The anion gap is the quantity difference between cations (positively charged ions) and anions (negatively charged ions) in serum, plasma, or urine. The magnitude of this difference (i.e., "gap") in the serum is calculated to identify metabolic acidosis. If the gap is greater than normal, then high anion gap metabolic acidosis is diagnosed.
An anion gap is usually considered to be high if it is over 12 mEq/L. High anion gap metabolic acidosis is typically caused by acid produced by the body. More rarely, it may be caused by ingesting methanol or overdosing on aspirin. [1] [2] The delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to ...
Blood tests for the diagnosis of diabetic ketoacidosis measure glycemia (sugar level), pH (blood acidity), and ketone bodies. As urgent medical treatment is often required when DKA is suspected, the tentative diagnosis can be made based on clinical history and by calculating the anion gap from the basic metabolic panel , which would demonstrate ...
When this happens the numerator is large, the denominator is small, and the result is a delta ratio which is high (>2). This means a combined high anion gap metabolic acidosis and a pre-existing either respiratory acidosis or metabolic alkalosis (causing the high bicarbonate) – i.e. a mixed acid–base metabolic acidosis. [citation needed]
Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. [1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [1] A person's breath may develop a specific "fruity" or acetone smell. [1]
A negative urine anion gap can be used as evidence of increased NH 4 + excretion. In a metabolic acidosis without a serum anion gap: A positive urine anion gap suggests a low urinary NH 4 + (e.g. renal tubular acidosis). A negative urine anion gap suggests a high urinary NH 4 + (e.g. diarrhea).
One difficulty in evaluation acid-base derangements is the presence of multiple pathologies. A patient may present with a metabolic acidosis process alone, but they may also have a concomitant respiratory acidosis. Winters's formula gives an expected value for the patient's P CO 2; the patient's actual (measured) P CO 2 is then compared to this ...
Other conditions that may present similarly include other causes of high anion gap metabolic acidosis such as diabetic ketoacidosis, toxic alcohol ingestion, and starvation ketosis. [2] Toxic alcohol ingestion includes methanol and ethylene glycol poisoning. [6] Pancreatitis, alcoholic hepatitis, and gastritis may also result in similar ...
