This is a very important question. All tests are based on statistics. If the result is positive, it means there is a high degree of medical certainty that there is IBS-D or IBS-M, based on elevated levels of antibodies to Cdtb and/or vinculin. Having a high degree of certainty in irritable bowel syndrome diagnosis can reduce the cost to patients, providers, and the healthcare system as a whole, and can prevent treatment delays. IBSchek may prevent patients from having to undergo more invasive and costly exploratory tests, and, more precisely, it can direct next steps in patient treatment.
