[Current status and prospects of laboratory tests for inflammatory bowel disease]

Inflammatory bowel disease (IBD) is a chronic inflammatory disease affecting the gastrointestinal tract, with a global incidence increasing year by year, and the incidence of IBD in developing countries has been increasing since the end of the last century. The pathogenesis of IBD remains unclear, which is the combined result of genetic, immune, diet, environmental and other factors. There is no gold standard for the diagnosis of IBD. Colonoscopy and mucosal biopsy are the preferred clinical tests, but these invasive and time-consuming methods are not conducive to early screening and frequent monitoring. Therefore, convenient, fast, non-invasive and reliable methods are urgently needed to assist the clinical diagnosis and evaluation of IBD. This paper aims to elaborate the laboratory diagnosis and monitoring methods of IBD based on fecal and blood indicators, which can provide ideas for the prevention, screening, diagnosis and monitoring of IBD, and help reduce its burden on people's living standards, public health and society.
