How Do You Test for H Pilori?

Every one who gets treated for h pilori have a test to confirm eradication. A stool base anagen or a uria breath test is done four weeks after completing the regiment. If it's, if the next subsequenta confirmatory test is again positive, that' when you start going into your second and third line therapies. The other thing i read is that theyre, they've tried looking into vaccine for it. So far, doesn't seem like they've had success for that.
