pattywacky posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsHello I have been having alot of medical problems lately. I have been sick for over 2 months, most doctors thought I have chronic fatigue syndorme. I have had every blood test taken and one of the things that was odd was a antigliadin antibody panel. My doctor said it doesn't necessarily mean I have celiac but on both the IGA and IGG I tested moderate to strong positive 38H. I know you have to have a biopsy to confirm, but I have been on a wheat free gluten free diet for 6 weeks. I am getting better but not sure if it is because of the diet or all the nutritional supplements I have been taking. I don't relish having the biopsy done and understand you have to start eating wheat again. Also, my Mom was told she had celiac a few years ago by a skin doctor because of an itching rash she had. She has been on the diet for 2 years and no more rash. So, my question is can I rely only on the IGG and IGA test? Is there ever a false positive on these tests? Thanks for your help.
