Introducing the blood test for IBS: ibs-smart

simple blood test that can definitively diagnose diarrhea-dominant and mixed IBS

Here’s something crazy:

Until recently, there was NO way to know for certain if a person had IBS (Irritable Bowel Syndrome).

And even if your doctor ruled out other diagnoses and landed on IBS, you had no way to know WHAT caused the IBS.

It felt like IBS was a medical mystery!

That’s why I have been so excited to share the new ibs-smart test with the SIBO SOS® Community. The ibs-smart test is a simple blood test that can definitively diagnose diarrhea-dominant and mixed IBS.

Here’s how it works:

ibs-smart tests for two antibodies (anti-CdtB and anti-vinculin) known to be elevated in patients with IBS-D and IBS-M. These antibodies are known to be triggered by gastroenteritis (AKA food poisoning), which is a key insight to help IBS, because further infections can significantly worsen your symptoms. (I’ve written about it before in this blog post.)

Find out for sure if you have IBS – and if food poisoning is to blame – with the ibs-smart test!

And even MORE good new – now you can order the test kit with an online prescription and get answers right away!

  1. Thanks! I read Dr. Pimentel say that a very high anti-vinculin could indicate that you might be in the 10% who do not respond to prokinetics. Do you know what number is considered to be “very high?”

      Hi Britta,

      In retrospect, we should’ve asked specifically what that number is! I’m sorry I don’t have that answer…

      We are getting ready to do another live session with him! We’re planning to have him back on to talk about his presentation at this year’s Digestive Disease Week. We’re still working on getting into his calendar. But when we do, I hope you can find the time to join us just in case we have time at the end to ask him that question!

      Stay tuned!

    1. Hi Claire,

      Wonderful to hear from you! Stool testing has its place. It’s for trying to find potential pathogenic organisms in the stool. It’s not perfect, but it does give you some useful information (provided you’re working with a practitioner who’s cross-referencing the test results with your symptoms).

      The ibs-smart test has a totally different purpose. It’s used to identify if you have IBS. So they’re for two totally different purposes!

      So, we can’t prefer blood over stool just because they give us two different information 🙂

      I hope that made sense! Good luck! Be sure to ask your practitioner about whether a stool or the ibs-smart test might be a better fit for you. Although during this time, I know it’s hard to get an appointment… I hope you’re keeping safe!
