Blood Tests And Accuracy Of Iga?

My almost 11 year old daughter has just been tested for Celiacs. The results came back with the IgA being slightly elevated. Hemoglobin being slightly below normal. However, the other two or three blood tests they use for Celiacs came back within normal range. I can't remember what they are. I think one of them was a IgG. Could she still have Celiacs?

Her symptoms are: Diarrhea 5 to 7 times per day with an occasional firm stool, although very tiny amount, followed by her next bowel movement being very loose or watery.

She gets canker sores periodically, unexplained fevers up to 3 times per month, she does not have the muscle strength or stamina of our other children. She complains A LOT of tummy upset, has very foul smelling gas although she is not always gassy. She will often fall asleep in the middle of the day if she is able to lay down for a bit. She complains of being tired and often will ask to ride in the grocery cart because her legs are tired. She is almost 11 and she has only gained 2 pounds in 2 years and only gained about 1 1/2 inches in height. The doctor that we saw was concerned about the lack of weight gain more so than the height and so tested her for Celiacs. However, because of the test results he decided to refer her to a gastro doctor.

We have not been to see the gastro doctor yet. I would like to go with as much info as possible.

Has anyone had experience with 3 of the 4 tests being normal and then the IgA being slightly elevated and still having Celiacs?

Her blood iron also slightly below normal.

Thanks!

What do you mean by IgA elevated. They should have tested for total IgA and also the IgA mediated anitbody to gliadin. Which one are you referring to? You really should request a copy of the lab results. It is your legal right.

She certainly has the symptoms. If they do an endoscopy and it comes back neg. they may say "no celiac", but the proof is ALWAYS in the diet and it is ALWAYS worth a try.

Thank you for your reply. I will see if my husband can pick up a copy tomorrow on his lunch break.

I'm seriously thinking about implementing the diet but hesitate to do so without a confirmed diagnosis as I know it will be a huge lifestyle change. I just don't want to do it if it isn't necessary, know what I mean? I also wouldn't start it until after the gastro doctor appt. If he doesn't find anything or give us any answers then I will start the diet as she has been this way for some time and something needs to change for her sake.

Thanks again.

Hopefully, I will be able to post more info about her blood results.

My husband just picked up my daughters lab results from the doctor. They were not real confident in interpreting the results. They have referred us to a pediatric doctor now, instead of a gastro, with the results. That appt. is next week. However, in looking at her results it says that the range for IGA is 53-204 mg/dL. Her results are Flagged as "high" with the number being 253. Is this the total IgA?

There are a few other numbers. The list looks like this:

AB Gliadin IGG - range is: 0.0-10.0 U/ml Hers is: 1.0 (normal)

AB Gliadin IGA - range is: 0.0-10.0 U/ml Hers is: 1.0 (normal)

t-TG IGA - range is 0-3 U/ml Hers is: <4 (does this mean she scored less than 4?) It shows she is normal.

Negative 0 - 3

Weak Positive 4 -10

Positive >10

t-TG - range is 0-5 U/ml Hers is: <6 Again, it says she is normal.

Negative 0 - 5

Weak Positive 6 - 9

Positive >9

Endomysial IGA says she is Negative or normal. Under Range it just says Negative.

Then the final item on the list says:

IGA range is 53-204 mg/dL Hers is: 253 mg/dL and they have her in the "high" column instead of the "normal" column on this one.

Is this final number the "Total" IGA?

Also her Hemoglobin is slightly low.

Does anyone know what this means? Our doctor didn't which is why he is referring us to a pediatric doctor to read the results. That's not until next week though.

Thank you,

Yes, this is the total IGA. It is needed to confirm the accuracy of the other tests, which measure specific antibody levels. The total IGA is to confirm that your immune system is producing antibodies in general at normal levels. If this test is low, then the other tests are all inconclusive. The fact that this test is slightly high does not indicate celiac disease, but it does confirm that your immune system is producing antibodies at a slightly elevated level, and therefore the other tests would show valid results.

In summary, if your total IGA was low, then it could mean that your negative results on the other antibody tests show a systemic immune deficiency and are not meaningful in terms of any specific antibody level.

      Diagnosed w Celiacs, but reacting to gluten-free Digiorno Pizza AND Kraft Zesty Italian Dressing

      By trents · Posted

      As I suspected, xanthan gum is one of the ingredients. It is a polysaccharide used as a texturing agent in many gluten-free products. It's hard to digest and causes distress for many celiacs. I can't say for sure if that was the problem but you might be on the lookout for it in the future. Muscle spasms can be caused by magnesium deficiency. Are you taking any vitamin and mineral supplements? I mean some things more potent than a multivitamin?

      Hello @Suze046 In the western world 40 to 60 percent are low or deficient in Vitamin D.  Malabsorption from Celiac Disease, avoidance of UV from the sun and seasonal variations can result in low vitamin D.  A simple 25(OH)D test will tell you your status.  Low vitamin D affects immune system, bone health, mental health.  I keep mine around 80 ng/ml (200 nmol/L). Choline has many functions in our body.  From the neurotransmitter Acetylcholine to fat digestion.  It is made by our bodies but in insufficient amount.  The major dietary source is from beef and eggs.  The RDA is 500 mg a day.  That would be equivelant to 3 eggs or 10 cups of cooked brocolli a day.  Choline is a significant portion of biliary phospholipids and is a crucial element for bile function.n.  I found taking Phosphatidly Choline capsules helps.  A homocysteine test can be indicative of choline deficiency.  Could we be overlooking a potential choline crisis in the United Kingdom?

      @trents thank you so much for your response!  When i was diagnosed, I was exhibiting mainly joint pain, hair loss, bloating, and allodynia (painful feeling from non painful stimuli). The muscle spasms only started after diagnosis, and it seems to only happen when I am severely glutened. It’s only happened twice, but it definitely makes me nervous when it happens.    In regard to the pizza, thats what i saw after i got sick from it. I’m still trying to figure out how to switch to ALL certified gluten-free goods.    for the dressing, here is the ingredient list:  WATER, VEGETABLE OIL, VINEGAR, SUGAR, GARLIC, SALT, RED BELL PEPPER, ONION, CONCENTRATED LEMON JUICE, XANTHAN GUM, POTASSIUM SORBATE, HERBS, CALCIUM DISODIUM EDTA, MONOACETIN, SPICES. and the link: https://www.kraftheinz.com/en-CA/kraft/products/00068100903577-zesty-italian-salad-dressing

      Welcome to the forum, @annamarie6655! Are the muscle spasms and joint aches a new pattern of reaction to gluten or have you experienced these in the past? Concerning DeGiorno's "gluten-free" pizza, we have had many reports from celiac.com members of gluten reactions from consuming this product. I believe it is one of those "gluten-free" products that is made from wheat (speaking of the crust component) that has been processed in such a way as to remove most of the gluten. The FDA regs allow food companies to use the claim "gluten-free" as long as the product contains no more than 20ppm of gluten. This works for most celiacs but not for those on the more sensitive end of the spectrum. There is another industry standard known as "Certified Gluten-Free" that is stricter, requiring no more than 10ppm of gluten. Certified Gluten-Free products use the "GFCO" logo. Concerning the salad dressing, could you list the ingredients in another post or link it? There are certain other ingredients besides gluten commonly used in gluten-free manufactured food items to give them acceptable textures that give a lot of celiacs problems.

      Hello, so I was diagnosed with Celiacs about 8 months ago. After being diagnosed, I have been trying very hard to maintain a completely gluten-free (and celiac safe) diet.  Two of the main times I had a huge reaction, it was from: - gluten-free Digiorno Pizza w Pepperoni - Kraft Zesty Italian Dressing (this was in canada if that changes anything) Both are marked as gluten-free. Following eating these items, I had a severe bout of diarrhea, uncontrollable and heavy muscle spasms throughout my whole body, and aching throughout every joint.   If these are both gluten-free, why would I be reacting to them? Should I be worried about a separate allergy?  In regards to the muscle spasms, should I follow up with someone about that?
