Patient selection: United States resident


The normal eosinophil count is < 38 eosinophils per square mm. There no significant difference in counts for biopsies from the corpus or antrum.


Criteria for histologic eosinophilic gastritis- both of the following:

(1) one of the following:

(1a) >= 127 eosinophils per square mm

(1b) >= 30 eosinophils per high power field in >= 5 high power field

(2) absence of causes for peripheral eosinophilia


eosinophils per square mm =

= (number of eosinophils in a microscopic field) / (field area in square mm)
