Two years ago
I was tested for Celiac Disease
by a doctor via stool analysis.
During this time I was following a gluten-free diet because it made me feel better, but didn't realize that I needed to continue eating gluten in order to obtain an accurate test result
I believe it needs to be done within 72 hours of gluten ingestion...
(not sure if that's the exact time or not)
My results came back "Borderline Diagnosis"
