Irritable bowel syndrome (IBS) is hard to diagnose as well as treat, but researchers at the Sahlgrenska Academy have discovered a way of confirming the disorder using stool samples. Granins (chromogranin A) have previously been shown to serve as biomarkers for other inflammatory diseases in the gut, such as ulcerous colitis and Crohn’s disease. The present study looked at the variants secretogranin II and chromogranin B and found that IBS patients have high levels of the former and low levels of the latter.
