The cutoff value of gastrin for diagnosing AIG with severe atrophy was reported as 395 pg/mL11, and Terao et al.17 set hypergastrinemia > 350 pg/mL as one of the criteria for AIG in a multicenter study, which is similar to the 355 pg/mL cutoff value for gastrin in this study. This evidence concerns the gene GAST and Atrophy.
