Dr diagnosed me based on this (blood results inside)

Hello.

I recently got very sick with lots of symptoms noted with celiacs. My Dr said I will need an endescopy to assess damage, but that the blood test I received were highly specific, and she went ahead and diagnosed. I'm just wondering if there is any way this is wrong?

My esr and immature granulocytes were both high too. But iron and b12 were fine.

 

Thanks!

The second of your tests, (TTG IgA) is not 100% specific: there are other causes of a positive test, including diabetes, heart failure, Crohn’s and others. (Also, people who have celiac disease can get a negative result with this test.) This test is machine-read. (Background: The enzyme TTG deamidates gliadin (a broken-down component of gluten). In reaction to the presence of TTG, the antibody immunoglobulin A (IgA) is produced. Raised IgA antibodies indicate short-term immune response, indicating ingestion of gluten 2-4 weeks preceding the test.)

The first test you present measures antibodies directed against deamidated Gliadin peptides (DGP) in human serum or plasma.

Immunoglobulin A lines mucus membranes and protects body surfaces. Found in highest quantities: eyes, mouth, nose, GI tract. Raised IgA antibodies indicate short-term immune response, indicating ingestion of gluten 2-4 weeks preceding the test.

So far, everything is strongly suggestive of celiac disease and as always I tell people to listen to their docs over us on the Internet. More tests than these are usually ordered to diagnose celiac disease - what you had is not the typical so-called Celiac Panel. But again, it's all strongly suggestive. You could always ask for another round of tests, more complete this time. That's what I did. My next round of tests still showed the same thing, so then I got the biopsies and was diagnosed based on those plus the previous blood tests. You will need to continue eating gluten-containing foods if you opt for more tests and you will need to continue eating gluten-containing foods for biopsies, as well.

I would not second guess your doctor as you have two strong positive tests that are very specific to celiac disease. I will assume that they have recommended that you go on a 100% gluten-free diet. This article may be helpful:

      Have you had celiac genetic risk testing? A celiac genetic test is accurate with or without gluten in your diet. If you don't carry the celiac risk genes you can effectively rule out celiac disease for life.

      Based on those results alone, it’s not possible to say you have celiac disease. The test that is usually most specific for celiac, tTG-IgA, is negative in your results, and the endomysial antibody (EMA) is also negative, which generally argues against active celiac disease. However, your deamidated gliadin IgA is elevated, and your total IgA level is also high, which can sometimes affect how the other antibody tests behave. Another important factor is that you were reducing gluten before the test, which can lower antibody levels and make the results less reliable. Because of that, many doctors recommend a gluten challenge (eating gluten regularly for several weeks) before repeating blood tests or considering an endoscopy if symptoms and labs raise concern. It would be best to review these results with a gastroenterologist, who can interpret them in context and decide whether further testing is needed.

      Since you compromised the validity of the antibody testing by experimenting with gluten withdrawal ahead of the testing, you are faced with two options: 1. Reintroduce significant amounts of gluten into your diet for a period of weeks, i.e., undertake a "gluten challenge". The most recent guidelines are the daily consumption of at least 10g of gluten (about the amount found in 4-6 slices of wheat-based bread) for at least two weeks leading up to the day of testing. Note: I would certainly give it more than two weeks to be sure. 2. Be willing to live with the ambiguity of not knowing whether gluten causes you problems because you have celiac disease or NCGS (Non Celiac Gluten Sensitivity). There is no test for NCGS. Celiac disease must first be ruled out and we have tests for it. Celiac disease has an autoimmune base. NCGS does not. GI symptoms overlap. In the early stages of celiac disease, other body systems may not be showing stress or damage so, symptomatically, it would be difficult to distinguish between celiac disease and NCGS. Both conditions require elimination of gluten from the diet for symptom relief. Some experts feel that NCGS can be a precursor to celiac disease.

      Hi Kayla Huge sympathies. I was diagnosed in December, after 8 months of the most awful rash, literally top to toe. Mine is a work in progress. Im on just 50mg dapsone at the moment but probably need an increased dose to properly put the lid on it. As you have been now glutened, I wondered whether it might be worth asking for a skin biopsy to finally get a proper diagnosis? Sue
