Q: What is I-FABP in intestinal ischemia?

Answer: I-FABP is an intestinal fatty acid-binding protein and is a good marker of intestinal ischemia. I-FABP is a water-soluble protein abundantly present in the mucosa of the small bowel from the duodenum to the ileum. It rapidly starts releasing into the bloodstream whenever there is a small intestinal mucosal damage due to ischemia.
