Sooz Fooz posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsWell I finally got some answers. Over the last 5 years I have had 2 biopsy's which both came back negative. My specialist decided to do the gene test and yes it came back positive to celiac. Can someone tell me why this test wasn't performed before going to have the biopsy's. I also get dermatitis herpeformes which I have figured out is my warning signal. How many others have unnecessary procedures? when a simple blood test can tell us the answer and if positive then have the biopsy to see if any damage has been done.
