What is IBSchek?

IBSchek is a blood test to diagnose irritable bowel syndrome (IBS). It was developed following a discovery that IBS often results from food poisoning. The toxin that occurs during an episode of food poisoning continues to attack the intestine long after the food poisoning is gone, and the body develops antibodies to fight this toxin.

Previously, an IBS diagnosis was one of elimination -- determining that you did not have other illnesses or conditions that could cause similar symptoms. It was an expensive, time-consuming and often frustrating process.

IBSchek looks for the presence of antibodies that result from food poisoning. If the test shows that you have those antibodies in your blood, there is a very good chance you have IBS. Test results are available within 24 hours after your blood test arrives at the lab. Your doctor will be able to give you a diagnosis and start treatment quickly.

If the test is negative or inconclusive, it is still possible you have IBS and may require further testing. The manufacturer’s tests showed results that were up to 90 percent accurate.
