ibs-smart™ measures biomarkers in your blood that indicate IBS with 96% - 100% certainty.




ibs-smart™ is applicable to patients with diarrheal symptoms and diagnoses diarrhea-predominant or mixed-type IBS (IBS-D or IBS-M). 

These biomarkers are not common in patients with constipation-predominant IBS (IBS-C).

The validation study for ibs-smart™ showed that elevated biomarkers indicated IBS with up to 100% certainty. This test is highly specific in distinguishing between IBS and IBD. 

Is ibs-smart™ right for YOU?

Have you been experiencing the following for at least a few weeks? 

  • Stomach pain and cramping

  • Frequent bloating

  • Unpredictable diarrhea

    • or Alternating diarrhea and constipation

If you have been experiencing those symptoms, ibs-smart™ could help you begin appropriate treatment quickly and prevent years of potentially unnecessary procedures like colonoscopies.

IBS can occur alongside other serious illnesses. Ensure that you have thoroughly discussed all of your symptoms with your doctor to determine whether additional testing is necessary. 

If either antibody biomarker is 'Elevated,' your test results can be considered 'Positive.'

You know with certainty that you have IBS.

The organic biomarkers tested by ibs-smart™ have a positive predictive value of IBS that is 96%-100%. 

You know the cause,

which can help personalize treatment.

If the measured biomarkers are elevated, your IBS developed from gastroenteritis (food poisoning). This means your gut microbiome has been disrupted, indicating that treatments that target the gut microbiome could be effective for you. 

Here's how food poisoning leads to IBS.

You could avoid years of additional testing and costs.

If your doctor determines you have no other alarm symptoms, further testing may be unnecessary.
