A member asked:

Is it okay to be already on a gluten free diet when you go for blood work to test for celiac disease?

2 doctors weighed in across 2 answers

Celiac disease: A skin biopsy and direct immunofluorescence test of the skin are performed in most cases. Your doctor may also recommend a biopsy of the intestines.

Yes and no: Being on a strict gluten free diet may make serologies for celiac disease falsely negative. If possible, eating gluten for a week or so prior is better.
