I know dr chia does a stomach biopsy to test for this. I'm due for a colonoscopy soon and was wondering if there is a way to test with that and is the protocol and what to do with the sample anywhere? I can't get an endoscopy because I have a bridge in the front hanging on by a thread. I can't risk it getting knocked out. But I'm going to ask. Please tag me. Also not sure if this is in the right place Sorry about underline. Can't figure out how to remove it. i searched other threads but it's too much for me right now. Boy I sound insane. Sorry. Lol @Hip can you help?
