Teenager Needing Help With Blood Results

Hello, everyone, this is my first post on these forums after i have been looking at them for about a month.

Alright, firstly, i am Australian and my mother was diagnosed with Celiac Disease about 10 years and she has been on a gluten free diet ever since.

However, she did not get blood drawn to assist with the diagnosis, simply because it was not yet developed, so therefore she is unable to help me with intrepreting the results.

I have a range of symptoms consist with celiac disease and i have an appointment with a gastro specialist in May after being sent their by a GP.

These are the results i returned on the Celiac AB Master Blood Test along with comments i recieved on paper:-

Anti Gliadin IgA < 5 U/ml (0-19)

Anti Gliadin IgG 58 U/ml (0-19)

Total Serum IgA 1.5 g/L (0.7-3.6)

Comments:- Anti- Gliadin antibodies are usually found in coeliac disease but also occur in other conditions. Endomysial or tissue transglutaminase IgA antibodies are more specific for active coeliac disease.

If clinically indicated, small bowel biopsy is suggested to clarify the diagnosis.

Obviously, my IgG antibodies are quite high, the numbers in brackets indicate the range the results should be in.

The doctor mentioned that the specialist might decide to either perform more blood tests or a biopsy. I presume these blood tests would be for Endomysial or Tissue Transglutaminase but i could be mistaken, they might have tested those in the first blood tests.

Also, everything else from the tests were normal.

Any advice or comments on my results would be very much appreciated.

Thank You.

PS:- sorry about the length of the message.

Welcome :)

Your results are high and they indicate that you may have celiac disease. I would suggest getting the Tissue Transglutaminase (tTG) test since that test is highly specific for celiac disease. If you want more testing done, make sure that you don't start the gluten-free diet until after your tests. If you start eating gluten-free before testing, your results may be false negative.

Thank Your very much for your reply,

Can you confirm that the standard IgA Anti Gliadin Test does not consist of a transglutaminase IgA test or endomsysial test?

I find it strange that the lab would not perform these tests on the first inspection.

There are four to five specific blood tests that should be done. The problem is many doctors out there are from the old school and usually run just one. Mine did, but it indicated Celiac Disease and so I got my diagnosis. Many people are missed because the full Celiac Panel is not done. The lab will only run the exact test that a doctor orders. Please be sure and stay eating gluten until all your tests are done. You don't want to scew the results so that you get a false negative. Good Luck and let us know how you are doing.

Thank You for the reply, i will continue eating normal foods and i'll keep everyone informed.

Also, i can't understand why a doctor would not perform a full celiac blood test.

It is very frustating especially when at times you feel like crap and you want to know why and as soon as possible.

I spose i have to take some of the blame but as a 19 year old living away from home i don't exactly know much about celiac disease and at 19 it can at times be daunting.

I wanted to add something, but I just have to DITTO all of these points!

While your doctor missed the ttg test, he/she did get 3 important ones.

The IgG test is more sensitive then the IgA, meaning there are less false positives and false negatives. However the IgG test is less specific, meaning Celiac is not the only cause of a positive IgG test.

With a neg IgA and a pos IgG, the next thing is to see if you are IgA deficient. The "Total Serum IgA" that your doc did shows a normal level of IgA, so you are not IgA deficient.

Traditionally the next steps would be to have your ttg levels checked...which your doc should have already done... and then have an EGD with biopsy.

Note that the ERG with biopsy is only a good test to "rule in" Celiac. This means that if the biopsy is positive, then you have celiac. If the biopsy is negative, it is a meaningless test as you could still have Celiac.

You're on a road where Celiac might be one of your desitinations, and from your bloodwork that is likely!

Let us know how it comes along!

Will do, thanks very much for the informative post.

My IgG was the only one elevated, and I was dx'ed by that and dietary response. My Dr. didn't feel the biopsy was necessary.

Positive dietary response is valid! Especially if there is a family history...

As far as the other conditions related to a high IgG, what are they? I can't find a listing anywhere, except maybe Chron's.

      New (possible) celiac diagnosis

      By trents · Posted

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      New (possible) celiac diagnosis

      By Judy M · Posted

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      Gluten free beer ?

      By Scott Adams · Posted

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
