I am so sorry you are having this issue. I know how frustrated you must be feeling.
From what I have learned the Serology 7 tests is the most advanced diagnostic panel for inflammatory bowel disease. With an overall accuracy of 92%, this unprecedented diagnostic test is the most comprehensive IBD test available with proprietary markers to help physicians diagnose inflammatory bowel disease ("IBD") and to differentiate the subtypes of Crohn's disease and ulcerative colitis.
I do not know how that negates the positive biopsy but perhaps someone else here would know.
Take care and keep posting, we are here to support you.
Bless you and gentle hugs,
