Negative Ttg Iga Without Total Iga Count?

Recommended Posts

My primary care doctor ordered a tTG IgA and a DGP IgG upon my request. I specifically requested a total IgA (technically I requested a FULL panel and specified a total IgA) , but it appears it wasn't ordered. After 2 weeks I have finally received the tTG IgA results and am still waiting on the DGP IgG results. The tTG IgA says this:

Tissue Transglutaminase Ab. IgA, Serum Quantitative

Result <2 U/mL

Reference Range 0-3

Obviously the result is negative, but without the total IgA count how much weight should I give to this result? I know there is some possibility that I could be IgA deficient, but what's the likelihood that this is a false negative without knowing my total IgA status? The doctor seemed very dismissive of my request for a celiac panel. I'm concerned that if my DGP is positive that she'll dismiss it due to the negative tTG IgA (I'm having this problem with my 5 year old who tested negative DGP IgA and weak positive DGP IgG). Thoughts?

Thank you!

You could try contacting the doctor and see if the lab has a blood sample saved which they could run the total IgA on.  My doctors have told me that this was possible to do in the past.  They save some just in case something unexpected comes up.

 

A positive IgG could be significant (even if the number is low) that is just my opinion from my nearly two years on the forum.   

 

I am hoping you will get a definitive diagnosis.

About 5% of celiacs are deficient in IgA, which is higher than the regular population, so there is a 5% chance of an IgA deficiency causing a false negative... but false negatives can happen even when a person is not deficient in IgA, as you saw with your 5 year old.

 

Most doctors recognize that a full panel should be run for at risk individuals - meaning someone who has celiac disease in their immediate family. If your tests are negative, I would push for more celiac tests, and that serum IgA; try to get whatever is available in your area.

 

Best wishes.

I would ask if they ran the complete Celiac panel, to include:

  • AGA (antigliadin antibodies)-IgA
  • AGA-IgG
  • tTG (anti-tissue transglutaminase)-IgA
  • EMA (anti-endomysial antibodies)-IgA
  • Total serum IgA

It is not uncommon to be negative in one and positive in another - that's why it is so important to run all of them.

I'm also not surprised that a 5 year old would have a "weak positive" result.  From what I understand, kids are even more difficult to diagnose because they haven't been alive long enough to produce high enough levels of the antibodies for them to really show up on the tests.  (not always, but it's more common with kids)  And the whole "weak positive" thing is bunk.  It's like saying you're weakly pregnant.  Keep pushing your doctor - or find one more knowledgeable about Celiac.

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      That is the goal, after all.

      Hello @catnapt, That's so true. Every person with Celiac Disease has different symptoms. There are over 200 that it mimics. Too many still believe that it is only a childhood disease you outgrow. Or it's psychosomatic or simply a fad. Idiots. It's easy to get angry at all of them. You just have to pick at the answers until you find...

      Celiac Disease causes more vitamin D deficiency than the general population because of limited UV sunlight in the winter and the little available from food is not absorbed well in the damaged small intestine.  Taking 10,000 IU a day (250 mcg) a day broke my depression. Taking it for eleven years.  Doctor recently said to not stop.  My 25(OH)D is around 200 nmol/L (80 ng/ml) but it took about six years to get there.  Increasing vitamin D also increases absorption of Calcium. A good start is 100-gram (3.5-ounce) serving of salmon,  vitamin D from 7.5 to 25 mcg (300 to 1,000 IU) but it is going to take additional vitamin D supplement to be effective.  More importantly salmon has an omega-6 to omega-3 ratio 1:10 anti-inflammatory compared to the 15:1 infammatory ratio of the typical Western diet.

      Thank you for sharing your thoughts.  I respectfully disagree.  You cherry picked a small section from the page.  I will do the same below: The agency is seeking information on adverse reactions due to “ingredients of interest” (i.e., non-wheat gluten containing grains (GCGs) which are rye and barley, and oats due to cross-contact with GCGs) and on labeling issues or concerns with identifying these “ingredients of interest” on packaged food products in the U.S. “People with celiac disease or gluten sensitives have had to tiptoe around food, and are often forced to guess about their food options,” said FDA Commissioner Marty Makary, M.D., M.P.H. “We encourage all stakeholders to share their experiences and data to help us develop policies that will better protect Americans and support healthy food choices.” --- end quote Anyone with celiac disease is clearly a stakeholder.  The FDA is encouraging us to share our experiences along with any data to help develop future "policies that will better protect Americans and support healthy food choices".  I see this as our chance to speak up or forever hold our peace.  Like those that do not participate in elections, they are not allowed to complain.  The way I see it, if we do not participate in this request for public comment/feedback, then we should also not complain when we get ill from something labeled gluten-free. Have a blessed day ahead, Known1

      Hello @catnapt, That's so true.  Every person with Celiac Disease has different symptoms.  There are over 200 that it mimics.  Too many still believe that it is only a childhood disease you outgrow.  Or it's psychosomatic or simply a fad.  Idiots.  It's easy to get angry at all of them.   You just have to pick at the answers until you find the ones that work for you.  I too suffer from not being able to take the drugs that work for "everyone else".  SSRIs make me twitch ane feel like toothpicks are holding my eye open, ARBs cripple me.  Statins cause me intestinal Psuedo Obstruction.  Espresso puts me to sleep.  I counted 19 different symptoms that improved from GFD and dealing with my nutritional defecits.  I couldn't breath through my mouth until I started GFD at 64 years old.   My son was born with celiac disease, biopsy diagnosed at weaning.   So why are we the one-percenters.  Why, after being silent for so long, does it suddenly flare? There is the possibility that you have both Celiac Disease and Non Celiac Gluten Sensitivity.  NCGS was not established as a diagnosis until 1980.  NCGS is diagnost by first elimating Celiac Disease as the cause, and showing improvement on GFD.  Nothing says you can't have symptoms from both.  Wheatbelly: Total Nutrition by Dr. Davis was helpful to me. We come to the forum to share what we've learned in dealing with our own symptoms.  Maybe this will help someone. Speaking of which if you don't mind; what is your 25(OH)D vitamin D blood level?  You mentioned a mysterious Calcium issue. Vitamin D, Calcium and Iodine are closely interactive. It is not uncommon for postmenopausal women to have insufficient intake of Iodine.   (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals You are a one-percenter.  You may need higher intake of some essential nutrient supplements to speed up repairing the damages.
