    Anion Gap

    Evaluates states of metabolic acidosis.

    INSTRUCTIONS

    We now have an ABG Analyzer to help with acid-base analysis as well.

    When to Use
    Pearls/Pitfalls
    Why Use

    Determining if a patient's acidosis also has an elevated anion gap.

    Unmeasured proteins (e.g. immunoglobulins in patients with monoclonal gammopathies or myeloma) may lead to a paradoxically normal anion gap. 

    Anion gap acidoses have a very different differential diagnosis than non-gap acidoses.
