Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Once your
colonoscopy report is normal, this is pretty assuring. In certain cases, where the test can be positive, which includes the following:
-Some vegetables, like turnips, cauliflower, radish
-eating red meat
-any source of GI bleeding (
epistaxis, gingival bleeding, hemorrhoids)
-
Aspirin and NSAIDs can also turn the test positive.
Therefore, another good idea is to get the test done again after restraining from the above things for a week.
Hope I have answered your query. Let me know if I can assist you further.
