Can Medication Affect Test Results? Labs?

Does anyone know if prednisone, remicade and/or imuran can affect labs? What about endoscopy/biopsies? If those drugs suppress the immune system, do they make the villi appear normal (albeit temporarily).

I've been asking this question everywhere but nobody seems to have an answer. If somebody knows the answer it would really help me out.

My guess is that they would. Have you asked your doctor?

My doctor had me take a celiac panel and many other blood tests because of the chronic itching and rash that I've been having knowing that I'm on prednisone. So I'm guessing that she either didn't think it could affect the results, didn't know, or didn't care. The results for everything came back negative but now I'm not sure if I can trust the results because of the prednisone. I'm having trouble trusting doctors because it seems that when they don't know the answer to something they just brush you off.

To the best of my knowledge, speaking strictly as a layperson, taking prednisone, Remicade, or Imuran, would not affect your anitibody tests. As they are all anti-inflammatory and immunusupressant, they would affect the levels of inflammation in your body (on biopsy), and would lower the results of a C-reactive Protein test (CRP) which measures inflammation levels in the body by blood test. But I do not believe that these drugs can suppress the gluten antibodies or magically make villi regenerate. I may be wrong about the antibodies :(

Hi kelliac,

My gastroenterologist gave me a clinical diagnosis of celiac disease even though my tests were negative (blood work and biopsy). I have the HLA DQ8 marker, reacted very strongly to a gluten challenge, and have family members with celiac disease, including 3 of my 5 grandchildren. He said that my prednisone and Imuran would suppress antibody production and allow my villi to re-generate.

I guess the bottom line is that we need to listen to our bodies. How do you feel when you eat gluten? How do you feel when you don't? If you feel better gluten free, then you have your answer! It doesn't really matter whether they call it celiac disease or gluten intolerance because the treatment is the same for both: the gluten free diet!

Good luck with everything!

Thank you for your reply, you've been very helpful. The first time that I took the blood test I had been on a gluten free diet for quite sometime but was still having symptoms so I thought that perhaps I was being exposed to gluten but not realizing it. That was before I knew that you have to be consuming gluten regularly for the test to be accurate. I also wasn't sure about how prednisone would effect the results but you cleared that up. I'm planning to retake the celiac panel because at this point I've had roughly 3 months of consistent gluten exposure in my diet. If the test comes back negative again I'll have some piece of mind knowing that perhaps celiac is not the cause of my itch and rash.

Please do not take what I said as gospel - I was only expressing an opinion on the basis of little research. I would seek further opinion on whether these drugs suppress antibodies. Since I made that post I have read others who think that they do :o Please be aware that there are posts on here supported by medical research and other posts expressing the poster's opinion which posts should be verified with further research before being relied upon. :)

      How long after being diagnosed with Celiac do you feel better?

      By trents · Posted

      Thanks for sharing, Karen. Certainly a needed reminder what we already knew (and I've posted many times on this forum) but sometimes forget, namely, autoimmune disorders tend to cluster. Where one is found, you can look for others to show up eventually. The thing that is unusual in your son's case is the onset of several of them at such a young age. My sister in law, who is in her early 60's has Crohn's and struggles with constipation so I don't think that is unusual with Crohn's. If nothing else, it's the outcome of not eating much because of the pain. Now that you know what is going on with your son and the Crohn's, we hope he is beginning to improve.

      How long after being diagnosed with Celiac do you feel better?

      By Nathan. · Posted

      Hi there. My son is turning 16 this month. He had an endoscopy and biopsy to confirm celiac. He went gluten-free and his pain never got any better. I think it got worse. Months went by. The pain started around 7th grade. He missed a lot of school in 8th grade, and a whole lot in 9th grade. He couldn't go to school in 10th grade. All along the gastroenterologist prescribed Hyoscyamine, didn't help at all. Cyproheptadine, no less pain. Peppermint oil, ginger, Miralax, Senna. Doc said he was constipated, but I couldn't get him to have Miralax daily. Eventually he went on Linzess and no senna or Miralax. Sorry this is long, there will be a point.  We gave his school not just a doctors not...

      I think it takes different people different amounts of time, but in my own case I had pain,  bloating and loose stools for some time, exacerbated by a lactose intolerance, which eventually went.  I would say the really bad diarrhea got better quite quickly, but the bloating pain carried on for a few months, until I was told to give up lactose for a few weeks.  That helped enormously and once I realised milk and yoghurt was the cause, after a short break I went back to lactose very gradually and felt a lot better.  Now I can tolerate it well. From Coeliac UK "The enzyme lactase is found in the brush border of the small intestine. This is why people with coeliac disease can be deficient in lactase...

      Inhaler problem

      By knitty kitty · Posted

      Hello,   The medication in these inhalers can cause a thiamine deficiency if used by someone already low in thiamine.  We don't absorb sufficient amounts of vitamins and minerals due to the inflammation and damage done to our villi in Celiac Disease.  Even a long term strict gluten free diet may not provide sufficient amounts of vitamins and minerals.  There are eight B vitamins that all work together.  Thiamine deficiency often shows up first because our bodies use so much of it and it can't be stored very long. Thiamine deficiency symptoms can appear in as little as three days.  Without thiamine, the other B vitamins may not be able to function properly.   Thiamine is needed to clear lactic...
