How Useful Are Blood Tests For Kids?

Just wondering, since the blood tests don't seem to me to be a great detector of celiac (of course this is just my impression).  How likely are they to be useful for kids?  I decided after my ongoing saga to go ahead and test my boys.  They are doing the TTG-IgA and IgG, as the other tests you all reference don't seem to be available here. 

 

They are 11 and 12.

My understanding is that false negatives are fairly common in children, but the test still seems useful because a positive result would be informative. My daughter got a clear positive on tTG-IgA (hers was 69, with anything over 4 positive) the week after she turned four years old. And she was not really eating much wheat at all at the time, though I did make sure she had at least one small serving every day in the month leading up to the test. Her biopsy confirmed celiac the following week.

If your boys' tests are negative, that wouldn't necessarily rule out celiac (especially if they have symptoms) - but if they have positive tests, it would be great to find that out now.

      Outgrow celiac?

      By Wheatwacked · Posted

      Testing can't alone be trusted.  Else why would it take so many years of testing and retesting and misdiagnosis to finally be told, yes you have Celiac Disease. As to what to eat, I like pre 1950 style food.  Before the advent of TV dinners.  Fresh food is better for you, and cooking from scratch is cheaper.  Watch Rachel Ray's 30 Minute Meals for how to cook.  Keep in mind that she is not gluten free, but her techniques are awesome.  Just use something else instead of wheat, barley, rye. Dr Fuhrman is a ex cardiologist.  His book Eat to Live and Dr Davis' book Wheatbelly were instrumental in my survival.

      Celiac and dermatitis herpetiformis has taken Me from Me

      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--thanks for the tip about Dupixent, and I've added it to the article:

      I just want to clarify that what I posted is a category of research summaries we've done over the years, and nearly each one shows that there is definitely a connection to celiac disease and migraine headaches. The latest study said: "the study did indicate some potential causal associations between celiac disease and migraine with or without aura, as well as between migraine without aura and ulcerative colitis...this study did not find evidence of a shared genetic basis..." Anyway, there is definitely a connection, and you can go through more of the articles here if you're interested: https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/migraine-headaches-and-celiac-disease/

      Celiac and dermatitis herpetiformis has taken Me from Me

      By SusanJ · Posted

      Two months ago, I started taking Dupixent for dermatitis herpetiformis and it has completely cleared it up. I can't believe it! I have had a terrible painful, intensely itchy rash for over a year despite going fully gluten-free. See if your doctor will prescribe Dupixent. It can be expensive but I am getting it free. When the dermatitis herpetiformis was bad I could not do anything. I just lay in bed covered in ice packs to ease the pain/itching and using way too Clobetasol. Dapsone is also very good for dermatitis herpetiformis (and it is generic). It helped me and the results were immediate but it gave me severe anemia so the Dupixent is better for me. Not sure if it works for everyone. I cannot help with the cause of your stress but from experience I am sure the severe stress is making the celiac and dermatitis herpetiformis worse. Very difficult for you with having children to care for and you being so sick. Would this man be willing to see a family therapist with you? He may be angry at you or imagine that your illness is a psychosomatic excuse not to take care of him. A therapist might help even if he won't go with you. Also do you have any family that you could move in with (with the kids) for a short time to get away? A break may be good for you both.

      @tiffanygosci, Thiamine deficiency is a thing in pregnancy for "normal" people, so it's exponentially more important for those with celiac disease and malabsorption issues. I studied nutrition before earning a degree in Microbiology because I was curious what the vitamins were doing inside the body.  See my blog.  Click on my name to go to my page, scroll to drop down menu "activities" and select blog.   So glad you're motivated to see the dietician!  We're always happy to help with questions.  Keep us posted on your progress!
