An anion gap test checks the levels of acid in your blood. Learn about the conditions that the test results can reveal, and what a high/low test result may indicate.

The anion gap test uses measures of electrolytes to assess the body's pH level. A high anion gap result suggests high acidity, which can indicate a health condition. Read on.

An elevated serum anion gap, particularly a value higher than 30 mmol per liter, can provide supportive evidence. However, other causes of a raised anion gap, ...

A high anion-gap metabolic acidosis, an increased serum osmolal gap, or both can suggest that one of the toxic alcohols is present in the blood, but these abnormal laboratory results are not ...

The anion gap was 41. The plasma osmolarity was 314 mOsm/L. ... As such, a patient late in their course may present with severe acidemia and a very high anion gap without an osmolar gap.

"Beta-hydroxybutyrate is high, anion gap is high. These patients are very sick. Don't just focus on pH and bicarbonate to triage cannabis users with type 1 diabetes presenting with DKA." ...

The anion gap, especially if elevated, can help direct laboratory evaluation and management. It is less helpful if the history does not support many of the causes for a normal anion gap acidosis.

The case: A 65-year-old man was found in a state of clouded consciousness of unknown duration. At hospital his Glasgow Coma Scale score was 9. Naloxone and thiamine were administered. A CT head scan ...
