There is no single diagnostic test for inflammatory bowel diseases. Diagnosis is established through a combined evaluation of medical history, physical examination, laboratory tests, imaging, and pathology. This comprehensive assessment not only enhances diagnostic accuracy but also facilitates the identification of other conditions that may coexist with inflammatory bowel disease and require consideration in the differential diagnosis.
In most cases, a diagnosis can be made based on medical history, physical examination, laboratory tests, endoscopic biopsies, and pathological evaluation. However, in complex cases, advanced techniques such as double-balloon enteroscopy and capsule endoscopy may be necessary to achieve an accurate diagnosis.
