This is a different expert.
The h pylori antibody test is not going to go away, as you already had it.
A stool test or breath test is needed.
Bloating can be from small bowel overgrowth and other causes.
These have different tests.
Hydrogen breath test...this is needed.
Stool, comprehensive analysis for parasites.
Scope above if you have not had this, I assume you have.
Hopefully you are still there.
Sorry for any problems or delays.
If you request me in medical specifically, I will get you prompt answers, and we can have a back and forth until you are satisfied.
