I took PPI but still will like that... could anyone here can share experience or know or hv been done this test before, what doctor tell bout it.

Hi selphie85

A CgA test can be used to test a few health problems but in your case i would say the doctor is testing for Atrophic gastritis....hope the test turns out good..best wishes..
