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?
