ibs-smart Blood Test Results Interpretation

Dr. Mark Pimentel​

Executive Director of the MAST program at Cedars-Sinai in Los Angeles, California.

Positive for IBS: Next Steps

  • Food poisoning is confirmed as the root cause.

  • A diagnosis available in a few days allows you to progress to treatment quickly.

  • Counseling the patient for food poisoning prevention is important because antibodies can elevate further.

Non-Indicative of Post-Infectious IBS

  • The patient may have an illness other than IBS.

  • The patient could still have IBS, but it may not be post-infectious in nature. 

  • This is a patient best suited for additional testing to help determine another cause for symptoms.
