Wondering Accuracy Of Blood Test For An 8 Yr. Old

Hi,

 

First off, I have Celiac and several family members (mom, brothers, cousins, etc).  Anyway, last fall my then 7 yr. old started complaining of stomach aches all the time.  Instead of having him tested for Celiac I just put him on the diet.  He was on the diet for 6 months.  Though it was a royal pain, he never complained of tummy issues all but a few times.  In March, he asked me if he could try not being gluten free to see what happened.  I let him and he was fine for the first few weeks.  He's been on gluten again for about 4 weeks now and within the last 2 weeks has started complaining more of tummy aches and diarrhea.  Anyway, at this point before he goes back to being gluten free, I would like a blood test so that I know the diet is necessary.  I'm wondering how accurate it is in children, and if he's been on gluten long enough to show the antibodies?

 

Thanks.

My daughter was dx through blood work then confirmed with an  endo at 7 yrs old. You need to be back on gluten for approx 6 weeks. 

 

good luck

The suggestion is one serving of gluten daily for six weeks. The more gluten the better, though.

My doctor said six MONTHS, so I know the answer can vary.  It is different for different people.  My blood test went from positive to negative within two weeks of being gluten free.  My son was still testing positive after 6 months of being gluten free.

I've read 8-12 weeks is your best bet for an accurate test. Longer is better as the antibody levels change at different speeds for different people. For instance, my tTG IgA was ALMOST normal after over a year gluten-free.

 

When you do get tested, make sure you get the DGP IgA and IGG, and tTG IgA and IgG done. Those two are the best for kids.

Longer with a steady amount of one slice of gluten containing bread is best.  Twelve weeks is what the University of Chicago recommends.

 

With kids it is tough....but as Nicole already mentioned...make sure your doctor orders both Deamidated Gliadin Peptide tests:

 

DGP-IgA

DGP-IgG

 

Good luck to you :)

      Refractory or super sensitive?

      By Levi · Posted

      What is the correlation in taking supplemental Magnesium with D?  I can attest to Dr. McCarthy when it comes to influenza. In all 7 full years that I took extremely high weekly dose D2 50K only once did I become ill with flu like symptoms. At the time I became ill I was sharing residence with a sibling, 3 children, and 1 additional adult - a full house that was almost daily trafficked by other children and adults. Total 7 years, other than contracting Covid twice at 22 months apart, when it comes to flu illness I was practically immune.

      I have taken D2 50K oral capsules once weekly for 7 years consecutively due to a dangerously low deficiency level of 17. It took 3 whole years before I reached D level 34, followed by higher D levels up to low 70s. Two or three times throughout the following 4 yrs my labs would show slight high TSH (hypothyroidism). Is it possible that the last 4 of the 7 consecutive years of D2 50K which gradually increased my D levels to 60s & 70s is causing current labs of high TSH, even though for at least the last 4 months I have reduced my D2 50K intake to half dosage, every other week vs. weekly?

      Can celiac cause widespread pain??

      By Scott Adams · Posted

      Untreated celiac disease is associated with arthritis and other autoimmune diseases which can cause such pain. These categories have research articles on this topic: https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/fibromyalgia-and-celiac-disease/ https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/arthritis-and-celiac-disease/

      Can celiac cause widespread pain??

      By Paula Andrews · Posted

      Hi! Did anyone experience severe body aches prior to being diagnosed?  Last year I suddenly experienced widespread pain, completely unexplained. After numerous tests with normal results I was diagnosed with fibromyalgia in August and started taking Cymbalta, which helped about 80%. Now other than pain, I did not have any additional fibromyalgia symptoms.    In the following months I started experiencing diarrhea, to the point where it was constant. In January I was diagnosed with celiac disease and microscopic colitis after having an endoscopy/colonoscopy. I've been gluten-free since that day and recently my pain level has dropped to ZERO.  I'm starting to wonder if I even have fibromyalgia, or if all of my symptoms were celiac and colitis.  I've seen several doctors and no one suggested this, but from what I'm reading it sounds possible.  The fact that I was diagnosed with two different diseases within a few months also seems odd. Has anyone else experienced all-over body aches with celiac?  And if so did the pain end after eliminating gluten?  Unfortunately I don't know anyone who has either celiac or fibromyalgia to talk to.
