Yes me. That's because I'm IgA deficient - have next to none. I had super high TTG-IgG. Also my endoscopy showed no villi damage but did show high IELs. My gi said positive blood test plus high IELs meant definitely celiac. He would have concluded celiac just from the blood work I think. 2 years later, strictly gluten-free the TTG-IgG slowly coming down...
