Hi all, so I've been suffering with symptoms for a while now - left-side abdominal pain (most tender & severe in the lower abdomen), some blood and mucus in stool, bloating, and some diarrhea and constipation. In the past I've had issues with nausea, though not so much recently. 6 weeks ago a stool sample test showed I had 'incredibly high' calprotectin levels and my faecal occult blood test was positive. Bloodwork (inc. iron levels, autoimmune markers, blood count, and inflammation markers) was all normal. I thought IBD was considered autoimmune, but my GP said it wouldn't show up as such in bloodwork. Can anyone confirm this?
Test results look good- I'm very confused
Today I had a colonoscopy and was told it all 'looks normal', no inflammation, nothing worrying to be seen. They took 3 biopsies to double check. Now I'm left feeling very confused as to why my calprotectin would be so high previously and yet now there's no inflammation in my colon. I can't imagine it was due to an infection that's been and gone, as I still have symptoms, and have had certain symptoms on and off for years.
I'm worried they could've missed something
Is it possible they could still find evidence of IBD in the biopsies, even though it looked normal? Could the calprotectin be high due to activity in the small intestines instead? Also, I know this is an IBD forum, but I'm also very concerned about the possibility of cancer, especially as it looked to me like the colon wasn't 100% cleared out. So, I'm worried they could've missed something. Not expecting anyone to know, but just in case, do you know if cancer could go unseen and then be found in a biopsy?
