Question About Test Results
0

12 posts in this topic

I have a doctor's interpretation of these results, but I'm curious about what others with experience would say about these:  

 

gliadin (deaminated) abs

     gliadin, iga        9            standard range <20

     gliadin, igg        48          standard range <20

 

IGA    157    standard range 78-391

 

Transglutiminase Ab, IgA      17   standard range <20

 

Endomysial Ab, IgA  <1:10       standard range DLT10

 

 

Thanks in advance.

What appears to be your DGP IgG is positive. It is often a good early test for the disease, unlike the EMA Iga which requires a fair bit of damage to register a positive - yours appears negative.

 

I would say it looks like you could be a celiac. DGP tests are pretty specific and sensitive to celiac. Yours is over double the accepted range.

 

Now... many doctors will say you could have a gluten intolerance with just one test positive and hum and hah over actually saying "celiac disease". I'm curious what your doctor said - I feel like I'm being tested! :wacko:

I feel like I'm looking at my results  :)  I also had only a positive DGP igg, and negative everything else, and I am not igA deficient.  I had an EGD with 8 biopsies, and since they came back normal, my GI diagnosed me with gluten intolerance.  I am also vitamin D and K deficient, and low in potassium.  I still say if it was only gluten intolerance, why is my body creating antibodies against food  <_<

 

interested to hear what your doctor's take on it was!

These were my results... I was tested after my three year old was diagnosed.  She said the IGg is generally over sensitive and since the total IGa was low (and all other results), we could "ignore" the elevated number.  Hmmm...

Your total IgA is normal, not low.  If it were low (i.e., did not fall within the normal range) then the other IgA tests would not be valid.

 

I would not, however, ignore the positive IgG.  We have posters on the board whose only positive blood test was DGP IgG, and they were positive on biopsy.

Yeah, this was from my daughter's Gastro doc. I planned on asking my doctor about the results. I am asymptomatic... but I know that doesn't mean I'm negative for Celiac.

This is the quote on the test:

The Gliadin IgG is generally over sensitive. We get it when screening because often patients with celiac disease have a low serum IgA and all of the other markers depend on that level. Since your total serum IgA was normal we can ignore the elevated IgG.

My question: Is there anything else it could indicate besides Celiac?

The DGP has, I believe, about 99% specificity for celiac disease.  And it is, as the doctor said, a very sensitive test.  It will often pick the disease up in its early stages before there is much intestinal damage.

so far no one has been able to come up with a reason for a raised DGP score besides celiac.  here's a thread I started regarding it

I think your doctor's explanation of discounting the DGP IgG test was ... pretty lame. Why would they run it if they are just going to ignore it?  I think some doctors just don't like to label it as celiac because they think the diet is "too hard" which is total hogwash - there are quite a few foods out there that would be harder to get out of our diet if you eat any processed foods at all... like corn!  Eek!

 

The DGP is a really good test. Sensitive is a GOOD thing.... And that was a gastro who said all that, eh? Sheesh.

Yeah, it was the pediatric gastro who said this.  She had no qualms about doing an endo and diagnosing my daughter, so I don't think she would necessarily be hesitant with me, but who knows.  I don't really know where to go with this.  Since she is not really my doctor, and i'm not under a doctor's care right now, I don't know how to follow up.  I think I will bring it up to her when my daughter has her follow up soon.

Your daughter has Celiac !

Doesn't that doctor know that Celiac is hereditary?   :huh:

That should be proof enough for the doctor: close family member + high DGP-IgG = do an endoscopy to confirm.

  (+ test the father)

father and sister were tested, and she said they were fine.  i saw sisters results... all in normal range, but i didn't see dad's... for all i know it is like mine was.  I have a follow up with her at the end of May for my daughter, so I will talk with her about it at that time.  thanks!

    • Hi Everyone!  Thank you for all your responses!  This site is so helpful and I appreciate everyone who replied to my post.   I was able to get an earlier appt with Maureen Leonard who was absolutely wonderful like you all said and after more testing and even a genetics test, my son now has a diagnosis of celiac disease.  He's been gluten free now for a few weeks.  He is doing very well on the diet so far.  He does seem to be sleeping better which was always a problem since he was an infant, so that is a good sign!  We test in 3 months and I hope that his iron levels go up. 
    • Are you substituting something for the PPI?    I'm not sure what meds will mix well with it, but you could ask the pharmacy or Dr. for advice on what might work.   I'm thinking you stopped something that may be helping in some ways, and are now allowing your symptoms to return.   If so, it makes sense to find something else to help with symptom control.   I don't know what products you have there.   We have Tums (calcium carbonate), Gaviscon (aluminum hydroxide with magnesium carbonate), Pepto and Kaopectate (same product), and Gas-X (simethicone).    I believe all of these can be taken with PPIs, but do check.    I don't know that Pepcid (Famotidine) can be mixed, but you could check that, too.   The Gas X really helps with the bloating and odd pains, as it breaks up the gas.  The Tums seems to help neutralize the acid and upset stomach / stomach pain.  These two are my mainstays.  You may have other products that could be as effective. Have you tried mixing bone broth with cornstarch or gluten-free flour to make a gravy?  Mix in some ground beef, chicken, or turkey, add some gentle veggies (carrots, or maybe a can of Chinese veggies?), a little bit of gentle spices for taste, and then put over gluten-free pasta or white rice.  Make a chicken sandwich with gluten-free bread.   Can you tolerate mayo?   Put a sprinkle of salt, pepper, and lemon juice on salmon, then coat with mayo and microwave.   Or mix some mayo with chicken or tuna for a chicken salad / tuna salad sandwich;  or eat just a scoop of it.   If you can tolerate dairy, Schar's newest version of table crackers are like saltines and are tasty.   If no dairy, try their breadsticks.  You could have either with soup or bone broth.   Schar's has enough fat to give you calories to help stave off weight loss, and you can add more by brushing a little butter on the crackers. You could try other casseroles with tuna or some lean ground hamburger.  Have you also looked at a possible new food intolerance?   I suffered for a few weeks before I figured out it was dairy for me.   Eliminating dairy wasn't enough.   I had to get rid of anything that might upset my stomach in order to start getting better.  I printed lists of low FODMAP, low acid foods, and low lectin foods, then selected only those foods that were on all 3 lists.   You might consider doing this with food lists that are right for you.  Hope this might spark some ideas!    
    •  I have a friend with MS, another with breast cancer and a third with RA.  At the same age my only problem is I cannot eat gluten!  So when I start getting frustrated about food I think about that and how lucky I truly am.  Once you get in the swing of it it gets easier and then you start to feel better which makes it all worth it.    Also when I first went gluten-free I read on this group about Mark's daily Apple and the Paleo community. I turned to that which was extremely motivating.  I've never seen so many people so excited about not eating gluten. It was a very positive energy and motivated me to find other foods to eat. Also, they love bacon! 
    • I know I needed the confirmation.  My hubby went gluten free per the very poor advice from my allergist and his GP.   It worked, but we really do not know if he has celiac disease.  He refuses to do a gluten challenge and I do not blame him.  We do know that gluten makes him sick.  He has been gluten free for 16 years.   So, when my GI suspected celiac disease, I could not believe it.  I had no tummy issues at the time, but was anemic.  Had been my whole life and it was blamed on a genetic anemia and menstruation.  I knew what being gluten free meant and I did not want to have celiac disease.  But,   I got positives  on the DGP and my biopsy.    Nothing like seeing something in writing.  I showed that to my extended family who was in denial as well.   I had a shared household with hubby all those years.  But after my diagnosis and the fact my kid started making things in the kitchen, we all went Gluten Free.  Great kid, but I could not trust her with my health!  If you DD has small siblings, consider all going gluten free.  They can eat gluten outside of the house.  That is what my kid does.
