New Blood Test Can Detect IBS
- Posted on: May 29 2015
Good news for those who might be suffering from irritable bowel syndrome (IBS), early diagnosis is now possible thanks to two simple blood tests. In the past it was usually a long, drawn out process to diagnose irritable bowel syndrome; other conditions would have to be ruled out.
A gastroenterologist at Cedars-Sinai in Los Angeles, Dr. Mark Pimentel, is the individual who created these new blood tests. His motivation for the tests was the fact that patients would often have to jump from doctor to doctor and undergo a series of tests in order to get a diagnosis that they are confident with. Dr. Pimentel believes that this process can often leave patients with more questions than answers. Luckily, with these new blood tests, many patients will now have the ability to proceed straight to therapy for their condition. This is great news, since irritable bowel syndrome affects an estimated 10-15% of the population in the United States. The symptoms of this condition include constipation, abdominal pain, bloating, and or bouts of diarrhea. IBS is very erratic with it’s symptoms, often causing fatigue and stress in an individual. In addition, it can also be traumatic for a person because they don’t know when it’s going to hit due to its unpredictable nature.
It took Dr. Pimentel 8 years of research to develop these tests. His tests are so precise however, that they are able to pinpoint when IBS developed. By identifying the presence of antibodies, anti-vinculin and anti-Cdtb, the blood test show reactions to the toxins associated with food poisoning. In order to validate the accuracy of these tests, Dr. Pimentel and his colleagues studied 3,000 people between the ages of 18 to 65 and compared participants with IBS with those who have celiac disease, inflammatory bowel disease (IBD), or have no gastrointestinal disease at all. Research revealed that the blood tests were able to identify the anti-vinculin and anti-Cdtb antibodies successfully with greater than 90% accuracy. It was also discovered that these antibodies were elevated in the participants who have IBS compared to those who do not have IBS. As a result, researchers state that these biomarkers will be helpful in distinguishing IBS from IBD. This is great news for the 40 million Americans who have IBS, they can now have a seamless method of getting a true diagnosis once and for all!
