How Accurate Are Blood Tests For Ceoliac?

Recommended Posts

Hi, for the past few months I have been pretty ill with stomack pains after eating, and my stomach seems to swell up loads after I eat (usualy I have waist of 24inch but it goes up to 32inch), especialy after things like curry, pasta and stuff that contain gluten. I have been realy tired lately, and I get quite alot of mouth ulcers. My aunt has ceoliac, and because of my symptoms I decided to go to a doctor to see if I also had it. I had the blood tests for ceoliac, thyroid function and kidney function, and all of them have come back satisfactory. I was just wondering if sometimes the blood tests are unaccurate for ceoliac? Does it sound as if I still have ceoliac? I am going back to the doctor next week to discus the results with the doctor, and she wants to monitor my weight to see if I am loosing any weight. Does it sound as if I need a endoscopy?

I'd be very grateful if you could help me with some of my questions, even if it's just an oppinion! :)

thanks

You should definitely 100% get an endoscopy. My brother's blood numbers came back high (meaning likely to have celiac), mine came back normal (likely to not have celiac. After we both had an endoscopy, we found out I had celiac, and he didn't. Having an endoscopy is the only way to know for you sure, and some of your symptoms are common for people with celiac.

Which tests did you have done?

The tTG and EMA are very specific for celiac and the chance of them being false in slim to none. Most initial tests do not consist of these so I would request them. Also you could be IgA deficient, which some celiacs are. That makes an otherwise positive test negative. I would get further testing dones though because of having it run in the family and experiencing symptoms.

I would also maybe recommend a gene test be done.

The problem with biopsies are that if they come back negative then that does not prove you do not have celiac. It just proves there is no damage yet. Did he have the basic blood panel or the full panel with the tTG and EMA done?

Thanks very much for the advice! Your very helpful! I only had the initial test done. When I phoned the surgery up to see the results the doctor hadn't commented about the ceoliac test only the thyroid and kidney function. I think now actualy that the doctor is still not rulling ceoliac out, and maybe thats why she didnt comment on the form. I phoned the lab up to hear the results and they said it was negative.

I dont have diarhea which I know is quite a common symptom ceoliacs have, but I do have loads of the other symptoms. I'll see next week what the doctor wants to do next. Does every one with suspected ceoliac have to have a colonoscopy as well as endoscopy. I'd absolutely hate to have the colonoscopy :unsure:

thanks alot for your help, and any more advice will be very much appreciated! Did any more of you get a negative result for the first initial test?

thanks

You do not have to have any specific symptom to have celiac. In fact, you do not have to have any symptoms at all. Alot of people actually get no symptoms but find out when other problems start or they were lucky and were able to catch it.

I never had diarrhea with celiac...I had the opposite.

As for bloodwork, my initial testing had 2 positive and 1 negative so they decided to do a full celiac panel and gene test and then that gave a very clear answer that I have celiac.

Forgot to add, one other symptom I have is slight depression and I am totaly exhausted. Usualy I am realy active, and dance, and I am studying in college. Last year I was realy hard working, but this year, I am totaly opposite, and have to make a big effort just to work for a while. I have always been on the go before this year. I used to do sport, long distnace running, and musical theatre, but now I dont seem to have any energy to do anything but lye down on the couch. Its pretty out of character for me to be this lazzy.

dont know if that could also be connected to ceoliac

There are over 200 symptoms that can be associated with celiac disease. Fatigue is actually a very common one.

Kaiti, I had the Iga testing.

When I participated in an IBS study (the one that informed me I had positive blood results for Celiac), they also did a bloat breath test to test for h. pylori, the bacteria that can grow in your small intestine and cause ulcers and bloat and for lactose intolerance. I was borderline positive for h. pylori overgrowth, and my doc put me on a round of strong anitbiotics with acid blocker that helped. Read up on h. pylori, and if it sounds like you, that could at least be a part of your problem and the test is not hard at all. I am not sure how expensive it is though, since I did it as a part of a study.

The right combination of blood tests are pretty accurate, but in real life use, they do still have false negatives. Follow up is a good idea, and if all else fails, TRY the diet and see if it makes a difference for you.

Thanks very much for your advice! You have been very helpful! :D

This sight has been so helpful so far! :P

Hi Thanks for answering my questions! I was just wondering does it cause discolouration on teeth, because my teeth need to be regarly polished because they get discoloured easily. The dentist never knew why my teeth were like this because I dont drink coffee, and when I drink tea its very weak, I wonder if theres a connection between this and ceoliac as well.

Fatigue is THE MOST COMMON one...even ahead of diarrhea.

I was jsut looking through the other boards and I noticed that people associate mucousy BM and floating BM as being bad. I have both these, but only have seen thr mucousy one once or twice. Is this another sign of ceoliac or is that due to other intestinal diseases or conditions?

thanks for any help! B)

      Certainly, it would b wise to have a gene test done if your physician is open to it as it would provide some more data to understand what's going on. But keep in mind that the genetic test for celiac disease cannot be used as to diagnose celiac disease, only to establish the potential to develop active celiac disease. About 40% of the general population possess one or both of the primary genes known to be associated with the development of active celiac disease but only about 1% of the population actually develop active celiac disease. So, the gene test is an effective "rule out" tool but not an effective diagnostic tool.

      Had Quaker gluten-free oatmeal last night and my stomach is a mess today. NO flu but def stomach stuff. Anyone else?
    • Roses8721
      So you would be good with the diagnosis and not worry to check genetics etc etc? Appreciate your words!

      For those who will likely remain gluten-free for life anyway due to well-known symptoms they have when eating gluten, my general advice is to ignore any doctors who push to go through a gluten challenge to get a formal diagnosis--and this is especially true for those who have severe symptoms when they eat gluten. It can take months, or even years to recover from such a challenge, so why do this if you already know that gluten is the culprit and you won't be eating it anyway?  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS--but those in this group will usually have negative tests, or at best, elevated antibodies that don't reach the level of official positive. Unfortunately test results for celiac disease are not always definitive, and many errors can be made when doing an endoscopy for celiac disease, and they can happen in many ways, for example not collecting the samples in the right areas, not collecting enough samples, or not interpreting the results properly and giving a Marsh score.  Many biopsy results can also be borderline, where there may be certain damage that could be associated with celiac disease, but it just doesn't quite reach the level necessary to make a formal diagnosis. The same is true for blood test results. Over the last 10 years or so a new "Weak Positive" range has been created by many labs for antibody results, which can simply lead to confusion (some doctors apparently believe that this means the patient can decide if they want more testing or to go gluten-free). There is no "Weak Negative" category, for example. Many patients are not told to eat gluten daily, lots of it, for the 6-8 week period leading up to their blood test, nor asked whether or not they've been eating gluten. Some patients even report to their doctors that they've been gluten-free for weeks or months before their blood tests, yet their doctors incorrectly say nothing to them about how this can affect their test, and create false negative results. Many people are not routinely given a total IGA blood test when doing a blood screening, which can lead to false negative interpretations if the patient has low IGA. We've seen on this forum many times that some doctors who are not fully up on how interpret the blood test results can tell patients that the don't need to follow a gluten-free diet or get more testing because only 1 of the 2 or 3 tests done in their panel is positive (wrong!), and the other 1 or 2 tests are negative.  Dermatologists often don't know how to do a proper skin biopsy for dermatitis herpetiformis, and when they do it wrongly their patient will continue to suffer with terrible DH itching, and all the risks associated with celiac disease. For many, the DH rash is the only presentation of celiac disease. These patients may end up on strong prescriptions for life to control their itching which also may have many negative side effects, for example Dapsone. Unfortunately many people will continue to suffer needlessly and eat gluten due to these errors in performing or interpreting celiac disease tests, but luckily some will find out about non-celiac gluten sensitivity on their own and go gluten-free and recover from their symptoms. Consider yourself lucky if you've figured out that gluten is the source of your health issues, and you've gone gluten-free, because many people will never figure this out.
