  • TEST INFORMATION

    gastriCORE ibs‐smart® test is a second‐generation biomarker test that measures the level of two antibodies, anti‐Cdtb and anti‐vinculin which are elevated in a majority of patients who have IBS with diarrheal component (IBS‐D or IBS‐M). This test is highly specific in distinguishing IBS from IBD.

  • CLINICAL HISTORY

  • METHODOLOGY

    Second generation biomarker – Enzyme Linked Immunosorbent Assay

  • RESULTIf either antibody is “Elevated,” the test results can be considered positive and the patient can be confidently diagnosed with IBS-D or IBS-M.
    If both antibodies are “Not Elevated,” the test results can be considered non-indicative of post-infectious IBS. Further testing may be required in this case.
    Antibody Detected Patient Value (OD) Antibody Levels
    Anti‐CdtB Ab 2.71 Elevated
    Anti‐Vinculin Ab 1.61 Elevated
  • INTERPRETATION
    Antibody Reference Interval Reportable Range
    Anti‐CdtB Ab 0.00 – 1.56 0.00 – 4.00
    Anti‐Vinculin Ab 0.00 – 1.60 0.00 – 4.00
  • COMMENTS
    1. ibs‐smart® measures validated biomarkers, anti‐CdtB and anti‐vinculin, used to diagnose irritable bowel syndrome (IBS) with 96%‐100% positive predictive value.
    2. These biomarkers are elevated in >60% of patients with diarrheal IBS (IBS‐D) and mixed diarrheal/constipation IBS (IBS‐M) indi‐cating the root cause of IBS is likely a lasting microbiome disruption from an instance of gastroenteritis.
    3. Elevated anti‐CdtB levels indicate an immune response to an instance of gastroenteritis.
    4. Elevated anti‐vinculin levels indicate an autoimmunity has developed.
    5. If either antibody is ‘Elevated’, the test results are positive and indicative of IBS.
    6. If both antibodies are ‘Not Elevated’, the test results are considered non‐indicative of post‐infectious IBS, and further testing may be required to diagnose the patient’s GI symptoms.
