Son's Celiac Blood Test

Since my son had hit his insurance deductible in Dec. and he was having a cholesterol etc. test done as part of a yearly exam, I had the doctor throw in the celiac panel since it would cost next to nothing at that point. He wrote "celiac panel" on the form. When I got to the lab, they wanted to know more specifically, and he said antibody test, basically. So here's what I see on the form with his negative results:

Gliadin AB IgA 4 (negative is <11)

IgA, SERUM 294 (Reference was 81-463 mg/dL) WHAT ON EARTH IS THIS???

(tTG) Ab, IgA <3 (where negative is <5)

Does any of this make sense to those of you who are familiar with the various celiac blood tests? I don't think this is a complete test. It makes no sense to me.

Also...if this is incomplete, why on earth do the labs do it this way????? :angry::angry::angry:

It's not the full panel, but it's not bad. That second test is the total serum IgA. You need to know that in order to be able to properly read the anti-gliandin IgA and tissue transglutimase IgA. All of those came back in normal ranges, denoting that he has no serum markers for celiac disease. He may still find gluten causes him problems, but the blood doesn't contain a lot of antibodies in him right now.

Its not the complete panel but it does include the most important tests. The IgG is missing but that is the least specific for Celiac....meaning if its positive it doesnt mean Celiac....but definately an intolerance. The EMA is missing but I think the tTG is the better of the two. The total serem IgA is important because it tells you that you're son is not IgA deficient which could lead to false negatives if he was deficient.

Thanks for the input! He doesn't really have any symptoms...I just took the opportunity to get in a cheap test since he was having a blood draw for the other things, just to see. I think I'll get him the Enterolab gene test, just to see what it shows....so he'll know whether to be suspicious later on in life in case something comes up.

Maybe you guys can help me, too. Ty just had his follow up yesterday with the pediatric GI doc. I asked the nurse for a copy of the lab work. Ty's tests were ordered by a pediatrician, mine & Walker's by our family doc, and Glenn's by his doctor. Ty was tested in July, Walker & I in August and Glenn in September. Only Walker and I went to the same lab to get the blood drawn, I have no idea where it gets tested...ie if each lab tests on premises or if they get driven to a central testing lab or what.

Glenn (Dad)

proteins & serology

immunoglobulin A result 2.54 reference range 0.60 - 4.20 g/L

anti-endomysial antibodies negative

screened at a titre of 1 : 2.5

Linda (Mom)

immunoglobulin A result 1.73 reference range 0.60 - 4.20 g/L

anti-endomysial antibodies negative

screened at a titre of 1 : 2.5

Walker (Big brother)

immunoglobulin A result 1.21 reference range 0.40 - 2.80 g/L (ref. range changed because he's smaller??)

anti-endomysial antibodies negative

screened at a titre of 1 : 2.5

Ty (has celiac disease)

immunoglobulin A not tested or else if tested result not in the file

anti-endomysial antibodies 1 : 160

screened at a titre of 1 : 2.5

The nurse suggested that they didn't do the immunoglobulin A because the anti-endomysial antibodies were so high.

Thoughts? Ty doesn't really have any GI symptoms, underweight and anemic (well...he shouldn't be anymore), but the doctor was pleased with results since September...Ty has moved up the scale from scrawny to skinny (doctor's words) his belly is gone, can't see the edge of his scapula on his back anymore, he's gained three & 1/2 pounds and 3/4" taller. The doctor didn't want to do a follow up blood test because he says that he is happy with the progress Ty has made and it was encouraging to me that he thought we were doing a decent job with the diet because of the results indicated by the external exam and suggested that if the diet IS working, as he thinks it is, he doesn't want a over eager lab tech to spot a "residual background glow" instead of the antibody glow and then the tech will feel obliged to report it and we'd get a false positive on the followup blood test. I still wish he'd done it so I could the numbers, but I didn't push it because he and the other doctor seemed so pleased with the progress so far.

      Help I’m cross contaminating myself,

      By Rogol72 · Posted

      @klmgarland, My dermatitis herpetiformis didn't clear up until I became meticulous about cross contamination. I cut out gluten-free oats and all gluten-free foods, dairy and gluten-free rice. Additionally, getting the right amount of protein for my body weight helped significantly in my body's healing process ... along with supplementing with enough of all the vitamins and minerals ... especially Zinc and Magnesium. I went from 70kg to 82kg in a year. Protein with each meal 3 times daily, especially eggs at breakfast made the difference. I'm not sure whether iodine was a problem for me, but I can tolerate iodine no problem now. I'm off Dapsone and feel great. Not a sign of an itch. So there is hope. I'm not advocating for the use of Dapsone, but it can bring a huge amount of relief despite it's effect on red blood cells. The itch is so distracting and debilitating. I tried many times to get off it, it wasn't until I implemented the changes above and was consistent that I got off it. Dermatitis Herpetiformis is horrible, I wouldn't wish it on anyone.

      Thank you so very much Scott.  Just having someone understand my situation is so very helpful.  If I have one more family member ask me how my little itchy skin thing is going and can't you just take a pill and it will go away and just a little bit of gluten can't hurt you!!!! I think I will scream!!

      It is difficult to do the detective work of tracking down hidden sources of cross-contamination. The scenarios you described—the kiss, the dish towel, the toaster, the grandbaby's fingers—are all classic ways those with dermatitis herpetiformis might get glutened, and it's a brutal learning curve that the medical world rarely prepares you for. It is difficult to have to deal with such hyper-vigilance. The fact that you have made your entire home environment, from makeup to cleaners, gluten-free is a big achievement, but it's clear the external world and shared spaces remain a minefield. Considering Dapsone is a logical and often necessary step for many with DH to break the cycle of itching and allow the skin to heal while you continue your detective work; it is a powerful tool to give you back your quality of life and sleep. You are not failing; you are fighting an incredibly steep battle. For a more specific direction, connecting with a dedicated celiac support group (online or locally) can be invaluable, as members exchange the most current, real-world tips for avoiding cross-contamination that you simply won't find in a pamphlet. You have already done the hardest part by getting a correct diagnosis. Now, the community can help you navigate the rest. If you have DH you will likely also want to avoid iodine, which is common in seafoods and dairy products, as it can exacerbate symptoms in some people. This article may also be helpful as it offers various ways to relieve the itch:

      My only proof

      By Scott Adams · Posted

      It's very frustrating to be dismissed by medical professionals, especially when you are the one living with the reality of your condition every day. Having to be your own advocate and "fight" for a doctor who will listen is an exhausting burden that no one should have to carry. While that 1998 brochure is a crucial piece of your personal history, it's infuriating that the medical system often requires more contemporary, formal documentation to take a condition seriously. It's a common and deeply unfair situation for those who were diagnosed decades ago, before current record-keeping and testing were standard. You are not alone in this struggle.

      Methylprednisone treatment for inflammation?

      By Scott Adams · Posted

      Methylprednisolone is sometimes prescribed for significant inflammation of the stomach and intestines, particularly for conditions like Crohn's disease, certain types of severe colitis, or autoimmune-related gastrointestinal inflammation. As a corticosteroid, it works by powerfully and quickly suppressing the immune system's inflammatory response. For many people, it can be very effective at reducing inflammation and providing rapid relief from symptoms like pain, diarrhea, and bleeding, often serving as a short-term "rescue" treatment to bring a severe flare under control. However, experiences can vary, and its effectiveness depends heavily on the specific cause of the inflammation. It's also important to be aware that while it can work well, it comes with potential side effects, especially with longer-term use, so it's typically used for the shortest duration possible under close medical supervision. It's always best to discuss the potential benefits and risks specific to your situation with your gastroenterologist.
