    When to Use
    Pearls/Pitfalls
    Why Use

    Patients being evaluated for possible IBS.

    • The Rome III criteria help diagnose irritable bowel syndrome (IBS).

    Points to keep in mind:

    • There remains no objective reference (i.e. ‘gold’) standard for IBS; the criteria were developed through a literature review and consensus process.

    The symptoms that define IBS are subjective and self-reported, making a classification system helpful. Moreover, there is evidence to support the notion that patients who meet formal Rome criteria may be more likely to respond to certain therapies.
