Strongly Positive Blood Tests, Inconclusive Biopsy?

After years of intestinal symptoms and other health problems, I read an article about celiac disease and asked my doctor for the blood tests. I had the tests done, and was referred to a gastro. who said that the tests were strongly positive, and scheduled a biopsy to confirm. At his recommendation, I went gluten free for 2 months and my symptoms completely resolved. I resumed eating gluten for 1 week prior to the biopsy and felt terrible.

I had the biopsy, and the gastro. said that although my biopsy looked abnormal, it was not necessarily indicative of celiac disease. He said that it looked like there could have been only partial damage due to the fact that I had only had gluten for 1 week prior or 'focal celiac disease'? He wants me to remain on the gluten free diet and have the blood tests redone in September. He said that if the test showed improvement and my symptoms remained resolved, that he would feel comfortable with a final diagnosis of celiac.

Does this sound right? Can anything else cause positive celiac antibody tests? He said that the blood tests were very convincing... so why do we need to wait? I feel confused and just want closure.

Thank you!

You have a good doctor, I hope you listen to him. It is unfortunate that they couldn't do the biopsy right after the positive blood tests. Your 2 months gluten-free and then just one week of a challenge is the most likely reason why your biopsies were inconclusive. Many doctors would want you to stay on gluten, no matter how sick it makes you and then redo the biopsy. Your doctor is doing it in a much better way IMHO, he is having you remain strictly gluten free and then he is going to retest and see if your antibody levels have dropped.

Stay strict on the diet and be thankful you have such a good doctor.

Your doctor is being ultraconservative. To answer your question, anti-gliadin IgA can show up in normal people. Anti-tTG antibodies can show up in other conditions like rheumatoid arthritis. Anti-endomysial antibodies are pretty diagnostic for celiac disease, especially if you feel better off wheat. Your doctor wants to see the levels fall because that is pretty much proof that they were caused by gluten.

That's OK because you need to return and be sure your blood tests fall to normal and the diet is working anyway. I understand wanting closure but to be honest, you're in a much better place than a lot of the people around here. There are folks on this board who are extremely gluten-sensitive but have negative tests and would desperately love a formal diagnosis of celiac to show their skeptical families.

Your body has already given you all the answer you need with the diet working so well. ;)

Thank you both very much for your replies... it is so hard to sift through everything on my own! My Anti-endomysial antibodies were very high, and my primary concern was that there could be another disorder causing this that I should be looking into, but this does not seem to be the case. My family have been very supportive, but I felt strange saying that I have celiac if I did not have a conclusive biopsy. I will keep on with the diet and be grateful :)

Glad to be of help. :)

This abstract might help a little.

Open Original Shared Link

It is done by a famous Finnish celiac researcher named Markku Mäki. In it he shows that people with high anti-endomysial antibodies and a mild damage biopsy like yours go on to develop a fully celiac biopsy if they keep eating gluten. People who were in the group who didn't eat gluten had the antibodies go away and the mild damage reverse. His conclusion is: "Patients with endomysial antibodies benefit from a GFD regardless of the degree of enteropathy. The diagnostic criteria for celiac disease need re-evaluation: endomysial antibody positivity without atrophy belongs to the spectrum of genetic gluten intolerance, and warrants dietary treatment."

In other words, even though some doctors won't say you're celiac without a strongly positive biopsy, you are close enough that you need the gluten-free diet. You could even show this abstract to your family if it helps.

A positive blood test, especially one with a positive EMA, is a diagnosis for Celiac Disease. At this point, the only reason to do a biopsy is if you want to see how much damage has been done. I still have trouble wondering why it takes so long for some doctors to become convinced that a person has Celiac Disease. Your blood work, coupled with the dietary response, is as good a diagnosis as they get.

Now you can get on with the job of a return to good health!

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By Xravith · Posted

      Yes, you are right. Indeed, I’ve been feeling anemic since the beginning of this week, and today I felt horrible during a lecture at the university, I was trembling a lot and felt all my body incredibly heavy, so I had to come back home. I’ll do a blood test tomorrow, but I’m just worried about the possibility of it coming back negative. I’ve been eating two cookies in the morning as my only source of gluten over the past two weeks—could that affect the final result?

      New (possible) celiac diagnosis

      By trents · Posted

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      New (possible) celiac diagnosis

      By Judy M · Posted

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      Patiently Waiting to See Results

      By Scott Adams · Posted

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      Gluten free beer ?

      By Scott Adams · Posted

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.
