Jonnybaldridge posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsHi I just got called with a positive blood test, double what it should be. I have to get an upper gi now. I'm really confused. I was sick back in August and had the test done as part of a work up. I've felt fine since and just thought it was a bug. How come I haven't had any symptoms or problems since? I'm just really confused with everything.
