Understanding the Results of Biopsy

Yes, they can tell from the biopsy whether it is a bug of C. diff. I once had the weirdest D for months, but no actual flare symptoms. I went through the whole thing: Blood work, stool sample etc. Turned out I caught Giardia lamblia. Strangely, only a colonoscopy with biopsies revealed that.

So, to answer your question, a biopsy can tell you whether your colitis is UC or bacterial and the like.

I just remembered I actually asked my doctor about bacterial causes and whether the biopsy would tell. She said something about the biopsy not specifically checking for bacterial causes. Kind of vague.

She said I need to have stool tests and a colonoscopy to find out more. I had a sigmoidoscopy.

She didn't seem to think my issues were bacterial because they have persisted for quite some time. I think they may be bacterial because I took a lot of antibiotics during and after multiple surgeries. I just want to know for sure. Guess I need a stool test or a colonoscopy.

Yeah, I agree. I wish I had the colonoscopy because now I lost my insurance due to getting laid off and I can't afford one. When I got the sigmoidoscopy, the doctor was looking for hemmroids. I understand why she did things the way she did, no one expected that UC was causing my symptoms... If I knew they could check for bacterial causes with the biopsy I would have definitely inquired into doing it but I didn't know any better. I should have pushed for a stool test but everyone was saying that it was not bacterial. It's annoying that doctors push their opinions on patients, if I want a stool test, I should get one. I would like concrete evidence that it is not bacterial even if the chances of it being bacterial are 1%.
