Test Results

I got the results back from my blood test today, and the Gliadin Antibody IgA and Tissue Transglutaminase IgA were negative, but the Gliadin Antibody IgG was a bit positive (It was 16 when normal is <11). The total IgA was below normal (It was 54 when normal is 80-450). The doctor called it inconclusive and I have a biopsy scheduled for Thursday. He also said that although they used to think the tissue transglutaminase was 99% effective, they now only think it's 90%. I am just confused about what the total IgA actually is, it was my most unusual. What does a defeciancy of total IgA mean?

I think you have IgA deficiency because the total IgA is used to rule it out but that was low. That can make your otherwise positive tests come back negative.

As fr as tTG goes...that is a wonderfully accurate test that is pretty good for detecting damage, soon to take place of biopsies in at least children for diagnosis.

A test they didn't test you for is EMA which is another pretty good test to help detect damage. Not as good as the tTG but the next best thing.

I was looking at more at my blood test results and noticed another abnormality. Although it isn't specifically with a celiac test, I think it might be related. I got tested for the TSH thyroid test, which I also had done in May. In May, it was 2.81, and now it was 3.31 (normal is 0.34-2.50) Although is says my values are not too abnormal, I thought it was a little strange because, if I understand it right, a higher TSH value means lower thyroid activity, then mine is on the low side. However, I've heard that lower thyroid activity causes a slow metabolism and weight gain, but I'm extremely skinny and unable to gain weight. I've always been thin and thought I must just have a fast metabolism, but according to the test it's getting to be slow, but I'm still not gaining weight.

Your values are only minimally high so maybe you don't see the effects yet. Yes a high TSH means low thyroid function and you need to keep an eye on your levels. There are also exceptions to every rule so you might be a thin person with hypothyroidism. I would get the full thyroid panel done....free t3, free t4, and another TSH. There are other thyroid tests but these are the best to determine function. Hope this helps :)

oops.....The best thyroid tests are Total T3, Total T4, and TSH....... The free T3 and free T4 can be affected by alot of non-thyroid stuff......

Actually the best tests ARE the FT4 & FT3 because these show whats actually *available* in the body....some of the hormones are *stored* and not free for the body to use. Not sure if I explained that very well <_<

You can still be Hypothyroid and thin...just the same as a hyperthyroid person can be overweight. There are no rules...but yes its more *typical* to be overweight as the metabolism slows down. Your numbers should be watched because they are on the hypo end as mentioned previously. I was Hyperthyroid but after taking radioactive iodine I went Hypo (which is the point). My TSH was at 23.5 and I didn't gain a bunch of weight...I've always been pretty small and that didn't change when I went Hypo.

      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!!

      Help I’m cross contaminating myself,

      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.
