Iga Results

Hi everyone

I've posted on here before with all of my symptoms. I had a blood test for celiac last month which came back negative. I went to the dogs today to get my iron tested and while I was there I asked what exact tests I had for celiac. She said I only had one which was iga and the result was 0.8. What is the normal range?

Thanks

Serologic panel

Of the commercially available serologic tests that aid in the diagnosis of celiac disease, no one test is ideal. Using multiple serologies increases the diagnostic yield. Therefore, in the United States, screening in patients with possible celiac disease should consist of a panel of the following serologic tests:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

The reason for the use of the panel to detect celiac disease is several fold. They include selective IgA deficiency (SIgA deficiency), lack of concordance of endomysial antibody and tTG, and the occurrence of seronegative celiac disease.

You need to be tested with the full panel.

Thanks for replying. Those links you guys have sent are interesting.

I think it was the IGA (EMA) one the doc did. She also tested me for wheat allergy and several other allergies which came back negative. If someone had celiac would their wheat allergy test come back positive??

I have looked on the internet and I must be stupid but I can't find anything which tells me what the normal range is for IGA, just so I can see where I sit.

Thanks

Normal, or ranges can vary from lab to lab. Each lab has their range of distinction.

Celiac and a wheat allergy are two completely different things. Celiac is an autoimmune disease, an allergy is still an immune response, but it's not autoimmune and the tests are based on two different component of the immune system. An allergy test is IgE based, and celiac testing is IgA/IgG based.

That being said, you can have one or both, but just because you have celiac doesn't mean you have an allergy, and just because you have an allergy doesn't mean you have celiac.

Ask the doctor for your test results so you can actually see what the result was compared to the range, and have her run a complete celiac panel.

Well I am actually waiting on a hospital appointment for a biopsy so do you think I should wait and see how that goes or do you think I should still get a blood test for full celiac panel?

      GI DX celiac despite neg serology and no biopsy

      So you would be good with the diagnosis and not worry to check genetics etc etc? Appreciate your words!

      Challenges eating gluten before biopsy

      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...

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.

      Challenges eating gluten before biopsy

      By Scott Adams · Posted

      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.
