“IgA Anti-tTG Antibody Titer Predicts Villous Abnormalities in Asian Adults with Celiac Disease”

https://pubmed.ncbi.nlm.nih.gov/38095156

This study found that in Asian adults with celiac disease, an IgA anti-tTG antibody titer of 10-fold or greater predicted villous abnormalities with a high positive predictive value and specificity, suggesting that a no-biopsy pathway could be applicable to about half of these patients.
