could crohns cause the ‘coeliac’ antibody to be positive in blood tests? (iga and ttg) Endomysial antibody IgA level ?

[Scott Adams]

In some cases, individuals with Crohn's disease may also have elevated levels of IgA and tTG antibodies due to the inflammation and immune response occurring in the gastrointestinal tract. This can potentially lead to a positive celiac disease antibody blood test, even though celiac disease might not be the underlying cause.

To differentiate between Crohn's disease and celiac disease, additional diagnostic evaluations, such as endoscopic biopsies of the small intestine and genetic testing, are often performed. Consulting with a gastroenterologist or a specialist in autoimmune disorders can provide a more accurate diagnosis and appropriate management plan based on individual circumstances.
