Wow, that one is fascinating. And, come to think of it, that would apply to my four-year-old. Her first celiac test was an EMA (negative) and one of the antigliadin tests (off-the-scale positive), which made the doctor say that she didn't have celiac disease. A year and a half later, when I finally pestered her doctor into sending her to a gastroenterologist, she had transglutaminase IgA and IgG tests (and antigliadin IgA and IgG tests) that were strongly positive. I wonder what would have happened if I hadn't pestered her doctor into sending her to a GI. Would the lab have eventually dug up her old blood samples and run transglutaminase testing on it the way this article says to? Man, that would be a weird phone call to receive. "Hi, remember that negative blood test on your daughter from several years ago? Well, guess what -- it wasn't so negative after all, and she may have this disease....."
