My Blood Tests And What To Do Next

7 posts in this topic

Here are my blood tests results. Does showing positive for Deamidated Gliadin Peptide Antibody, IgA (DGP IgA) with 9.7 EU/ml and negative for the other tests suggests I should schedule a biopsy? What does this mean given your experiences?

I posted this comment yesterday on another discussion:

I do not understand why abiopsy is needed when this individual shows positive for celiac disease. I askthis because I have been suffering digestive issues for my entire life that areconsistent with gluten intolerance. I also had a rash last year for 4 monthsthat I now believe is/was dermatitis herpetiformis. A few weeks ago I was(blood) tested and it came back positive for Celiac Disease. I do not have acopy of the test with me at this moment to provide my numbers and I wonder nowis it really important to have a biopsy done to further confirm celiac diseaseor not.

Trying to understand what to do next...

PROMETHEUS Celiac Serology

_________AssayResult________________________________Value_____Reference Range

DeamidatedGliadin Peptide Antibody, IgG (DGP IgG)..............<0.4EU/ml.........< 1.3 EU/ml

DeamidatedGliadin Peptide Antibody, IgA (DGP IgA)................9.7 EU/ml.........< 2.9 EU/ml

Anti-HumanTissue Transglutaminase IgA ELISA (TTG IgA)........ .04 U/ml.........<10.3 U/ml

Anti-EndomysialIgA IFA (EMA IgA)...............................................Negative...........Negative

Total Serum IgA by Nephelometry (Total IgA).............................158mg/dl..........44-441 mg/dl

I am waiting for my Doctor tocall me back to discuss the merits of doing a biopsy.

I am not soliciting any medical advice; just your feedback is greatly appreciated about what you would do if this were your blood tests results given the above scenario.

Thanks,

Richard

The DGP is supposedly one of the most specific tests for celiac, according to Dr. Rodney Ford. Therefore, I would assume I had it. Whether or not you choose the biopsy is up to you. I don't know what your symptomatology is and whether there would be anything else that could be found by having the EGD, other than say a hiatal hernia or a duodenal ulcer. Doctors generally like to do the biopsy for confirmation as it is the so-called "gold standard" (how I hate that term :P ) of diagnosis, but it is your decision whether or not to have it. If your insurance would cover most of the cost, is is a relatively low-risk, painless procedure (you are sedated and given a medication to make you not remember it). Regardless of what it revealed, based on your blood test alone I would go on the gluten free diet for a good three-month trial to see if there was improvement/resolution of your symptoms.

Only you can determine if it is important to you to go ahead and have the procedure, which, if positive, will give you that piece of paper that says "celiac" on it. Remember, this can be a positive in convincing friends and family of your need for the gluten free diet, but we have heard of it being a negative when it comes to health and life insurance - not from all companies, but it has happened.

Good luck in your decision-making. :)

With the DGP and DH I don't think there is any doubt that you are celiac, no matter what the biopsy shows.

The biopsy would let you know the degree of damage and give you a benchmark if you decide to be re-biopsied later in life to confirm that the gluten-free diet is working. Some people find it difficult to stick to the diet without the proof provided by both blood and biopsy, but that's a double-edged sword. The biopsy can come back false negative because the damage can be patchy and it's missed by bad luck. Then you are left scratching your head.

Welcome to the board. I agree with the other posters. The choice to do the biopsy is up to you. No matter what the biopsy states you do need the diet. There can be false negatives on the biopsy. One of the reasons is that damage can be patchy and with 22 ft of small intestine a damaged spot can be missed. One other option is getting the rash checked to see if it is DH. They would need to biopsy the area next to the rash not the rash itself. A dermatologist would do that. They do need to be looking specifically for DH so bring your panel results with you if you go that route. A diagnosis of DH is a diagnosis of celiac even if folks don't have stomach or other celiac related problems.

If you do have DH you also want to avoid iodine until the rash has been cleared for a while.

Thanks for the feedback.

Sticking to a gluten free diet for me will be a challenge. I have had some interesting digestive situations while traveling across country by motorcycle and hope that a proper diet will changethat.

Wish I could find a gluten free girlfriend who liked to take motorcycle adventures everywhere and ski, snowmobile, hike,and... I don't know anyone personally who has gluten issues. It was reassuring to find this forum.

You will get used to gluten free lifestyle. It does seem challenging at first but it is quite doable.

As to finding a gluten free gal who would like doing what you do, well we are out there. We don't unfortuately have gluten free tattooed on our foreheads but single gluten free gals do exist and many of us wish we could find a good gluten free guy. One thing you might consider is going to a few gluten-free support group meetings if there are any in your area. You might meet someone that way.

Thanks for your words of encouragement. And for the idea of going to a local support group meeting. I will keep my eye out for those gluten-free tattoos.

    • After their seven-month-old baby died weighing less than 10 pounds, a mother and father in Beveren, Belgium, are standing trial on charges that they starved the child by negligently providing an alternative gluten-free diet, with no medical supervision. The couple, who ran a natural food store, put their son Lucas on an alternative gluten-free, lactose-free diet, which included quinoa milk, despite doctors describing it as unsuitable for developing infants.

    • Thank you so much for the reply, the book recommendations and the link. Really useful and I appreciate it.  Will definitely look into them.  Thanks again. 
    • an allergy test for tap water sounds quite suspicious, i've never seen any type of water listed as part of a food allergy test panel. i can't imagine how that is possible to test for, sounds like it would be a extremely rare allergy also doesn't tap water vary depending where you are. do you have a reaction to drinking water? what are your symptoms when you eat those foods?
      if it was an IgE allergy test, i believe the blood test more commonly has false positives than the skin scratch test but false positives are very common for both thats why there is usually a disclaimer saying that it may not be nesscessary to cut out all positive results especially if you have no allergic reaction after eating it. you allergist may be able to offer you some kind of allergen immunotherapy or a dietician referral.
      if you had the IgA/IgG food intolerance/ sensitivity testing, the same type of testing that is promoted a lot on instagram, it is not scientifically accurate. the positive results just indicate food you have been exposed too which are then wrongly interpreted as meaning they are allergies. so i definitely wouldn't make any significant diet chances based those results. other than an elimination diet there is no accurate testing for food intolerances although it would be great if there was. its possible that you could coincidently be intolerant or allergic to some those positive foods or you may have no problem with them.

    • Are you sure TTG IGA was 1? Anyway, a high on any one test should lead to a gastroenterologist doing an endoscopy to confirm celiac. Your not supposed to go gluten free until after all testing is done. Your results show high for dgp iga and dgp igg. Not a doc, my opinion only.
