I‐FABP, which is primarily limited to the mature enterocytes of the small intestine, was reported to be increased in cases of acute ischemic bowel injury (Gollin et al., 1993), necrotizing enterocolitis (Abdel‐Haie et al., 2017), atresia coli (Yıldız et al., 2018), enteritis (Ok et al., 2020) and parvoviral enteritis (Gülersoy et al., 2020). Here, FABP2 is linked to necrotizing enterocolitis.
