Test Results Help Please

Hi,

 

I just returned from an appointment with my GI. She said I am negative for celiac, however, the copy of the test results I received said "supports a diagnosis of celiac." I am obviously confused. I went back to ask her why she said it was negative, and she didn't have time for me. Suffice to say, I won't be going back. But I do have these results and I'd like your opinion on how to interpret them.

 

Deamidated Gliadin Peptide Antibody - IgG - 43.0 EU

Deamidated Giagin Peptide Antibody IgA - 9.3 EU

Anti-hunman tissue transglutaminase igA - 75.0 EU

Anti-endomysial igA IFA - positive

total serum iGA by Nephelometry, total igA - 129

 

One ellele HLA DqA1*05 of Dq2.5 detected, HLA DQB81*02 not detected.

Celiac risk haplotype not detected

 

I suspect because I do not test positive for the gene, she said I was negative for celiac? Any opinions? Would really appreciate any help!

 

For some reference, I blood test positive for a wheat allergy and I've been avoiding gluten for almost three weeks because I suspet celiac.

 

thank you!

Welcome Ami!

 

Looks like your doctor is wrong and you do have Celiac Disease in addition to your wheat allergy - Make sure your primary doc gets copies of all these tests -- unless you want to proceed with an endoscopy, there is no need for a celiac specialist.  If you decide to proceed with an endo -- try to find another GI that has training/experience with Celiac Disease.

 

Do you have the ranges for these tests -- they certainly look like they support a diagnosis of Celiac Disease - especially the positive Anti-Endomysial IgA -- also known as EMA-IgA.

 

Were you already gluten free for a time before these antibody tests were run?

 

Let us know the ranges if you have them.

Hi Lisa,

Thanks for the quick reply. These are the ranges listed on the paperwork, in parenthesis.

 

Deamidated Gliadin Peptide Antibody - IgG - 43.0 EU  (<4.9 EU)

Deamidated Giagin Peptide Antibody IgA - 9.3 EU  (<6.1 EU)

Anti-hunman tissue transglutaminase igA - 75.0 EU (<10.3)

Anti-endomysial igA IFA - positive  (range, negative)

total serum iGA by Nephelometry, total igA - 129   (<3 years, 8-220, 3-13 years 41-395, >13, 44-441)

 

I don't know how to interpret any of the above!

 

I've been wheat/gluten free for 3 weeks, on Saturday. At the time of the above blood test, I was about 2 weeks free.

 

What leads you to quickly say that yes, I am celiac positive?

 

Thanks for any help! I found another doctor for a follow up in two weeks, will stay gluten-free regardless of all of this! My allergies seem to be clearing although my stomach issues are roughly the same since starting gluten-free.

Every one of your tests was positive. Get a new GI or like Lisa said make sure your PCP has these results.

Every one of these tests is strong positive, which is what it looked like - but I do like to see ranges because ranges vary between labs.

 

Glad you'll be seeing another doctor soon.

 

It takes time for symptoms to improve gluten-free.  Sometimes it is days, weeks, months and sadly even years....but things do improve.  Healing happens.

 

The tTG-IgA and EMA-IgA both indicate there is damage within your small intestine caused by an autoimmune reaction that your body has to gluten.  This is not an allergy, but a person can be both celiac and allergic to wheat, barley or rye.

 

The  Deamidated Gliadin Peptide (DGP-IgA and IgG) are tests that measure the antibodies your body is producing to one of the peptides in the protein of Gluten - called Gliadin.

 

Hope that make sense.  

 

If there is a chance that you will be having an endoscopic biopsy you will need to continue to consume gluten each day -- it can be very tough to add it back in, so talk to the new doctor about your options.

 

Here is a great thread for those newly diagnosed and those new to living gluten-free:

Thank you all SO much! What do the allelle results mean?

 

Do you think that she interpreted the results as negative simply because I did not test positive for both genes? How can she be so stupid, to put it not so mildly?

 

With these results, is there ANY WAY I can not have celiacs, not taking into account possible testing errors or such?

 

Looking forward to getting to know everyone here more, since I think I'll be staying around :)

    • It sounds like your hives resolved.  I had a six month bout with them.  Antihistamines really helped.  My doctors are not sure if Mast Cell or autoimmune is the root cause.  
    • My kid has Raynauds.  It freaks her classmates out.  She wears shoes and wool socks all year round and we live in a warm state.  It is autoimmune.  She manages it by layering, turning up the heat, use lots of blanket throws.   I have Hashimoto’s and celiac disease.  So, having multiple autoimmune issues is common.  
    • Well, you do need to replace some things because they are too porous or damaged to remove gluten.  Things like old wooden spoons, scratched non-stick pans, toaster, colander, sponges, etc.  Honestly, the list is long, so try getting a few celiac books at the library or Amazon.  Consider reading through the Newbie 101 thread under the “Coping section”.    You should see some minor improvement soon.  It does take time to heal.  Most  around here will say it takes a year!  
    •   When I woke up from my Endoscopy and was told I definitely had celiac disease the first thing I asked my doctor was do I need to get all new kitchen stuff? He assured me that I did not, and as long as my pots and pans and everything else was washed after being used to cook gluten I would have no problems. Well, I'm 10 weeks into my gluten-free diet and still feeling crappy as ever.  I have not been eating out unless the restaurant is 100% gluten-free (I'm lucky there are several near me).  I am very careful that everything I use to cook my food is thoroughly cleaned at home, but is this really enough?  Did you guys need to replace most kitchenware in order really avoid being cross contaminated?   I'm curious to get some opinions before I spend a bunch of money on new/separate stuff.  Thanks!  
    • They have all given you good advice. Like Ennis_Tx said this is not medical advice. Just some observations. Ennis_Tx mentioned already a good B-complex. But people who have Perncious Anemia low B-12 have "Pens and Needles' feeling in their extremities. Mine was much more pronounced when sleeping. . . while sleeping my nerve ending would go to sleep. This would wake me from my sleep.  I would shake them awake/loose much like a leg that had fallen asleep while awake.  We have all felt that feeling before except the whole side of body's nerve ending would tingle/fall asleep enough to wake me from my sleep. Once taking a homocysteine tablet (B6,b12 and folic acid) tablet call FABB for the abbreviated ingredients under doctor's supervision this "pens and needles' went away. This also happened in my finger and toe tips while awake as if I had pinched a nerve in my back. These sensations are now in remission. Also if you think it is Rynaud's then try Niacin or Niacinamide.  It is a natural vasodialotor and the 'warm sensation" people take when using Niacin especially in a work out supplement is Niacin they add to enhance athletic performance for body builders.. . . because this opens capillaries approx. 10 % more allowing more air into the muscles thus improving their work out. This flushing goes away after a couple days of using Niacin.  The Niacinamide form does not flush the way the Niacin form does but provides the same benefit. Both Niacinamide and Magnesium each lower blood pressure approx. 10% each this way.  But if BP is a real problem for you  take the Homocysteine tablet mentioned above or just Folic Acid by itself. My BP is now normal after taking Folic Acid because it controls' how/what triggers constriction in our blood vessels thus effectively controlling BP. These are some times that I have used to improve my circulation. *** again this is not medical advice just things that have helped me with similar issues.  I hope this is helpful. 2 Tim 2:7 “Consider what I say; and the Lord give thee understanding in all things” this included. posterboy by the grace of God,
