Don’t know your ‘testing method’ …but most doctors ~only~ do a blood test..from dealing with my dad‘s case and his doctors‘ testing method. Hopefully, your doctor is testing under another method. Many of the test methods are discussed in the link below.
Also.. somewhere within my prior research, but I can’t find/remember where, that once a person has h-pylori the blood will always (always under proper lab conditions-steps) test positive for the bacteria. And all one can do is reduce, bring down the bacteria…to a more controllable dilemma, less noticeable distress/es.
You may…may look-research ‘serrapeptase’ since your have no ‘doorway’ for help open as yet- up to this date..forwhatitsworth in our trial&errors of personal learning in the ‘repetitive onTheJobTraining’ for good health. I understand one needs to take large amounts of serrapeptase to gain control for various poor health issues and drop to a self determined maintenance amount/dose….
Regarding H. pylori blood tests, the ACG (American College of Gastroenterology) 2007 guidelines state that "… a positive test is no better than a coin toss in predicting the presence of active infection."
