<<Disclaimer: Verify this information before applying it to your situation.>> Hi Everyone! I was biopsy diagnosed 8 years ago. 4 months ago, I sent the necessary blood samples for myself and my 2 children, who have not yet been tested, to the Center for Celiac Research University of Maryland. I just received the test results. Mine were incredibly normal (whew!), but 1 of my sons had a positive serology. Does anyone know where to find interpretation and explanation of these tests. I would like to have some understanding before I take him to the GI. IgG-AGA IgA-AGA EMA (IF method) Total-IgA tTg-IgA tTg-lgG Thanx...Carol, Mahopac, NY
