Childrens "negative" Blood Test Results

I had my children, ages 5 and 8 tested after I was diagnosed with celiac disease. The only one of the tests that came back positive was the "Antigliadin Abs, IgG". My 8 year old had 51 and my 5 year old had 97. My gastroenterologist and pediatrician said that overall they test negative even though these results are high positive. What does the IgG indicate? Why do they test for it if it is not an indicator of celiac disease? Is tTG really the only thing I have to be concerned about?

Well the full panel really will show some insight. Every test kind of has its piece to the puzzle. IgG and IgA are used to pick up gluten antibodies and a problem with gluten in the body. This is usually the first indication of celiac.

tTG and EMA are used more to detect damage in the intestines-these are the best 2 tests and pretty accurate.Then there is the total serum IgA which is used to rule out IgA deficiency. If they are IgA deficient then that can be why IgA came back negative.

If just the IgG comes back positive with all the testing it may be in beginning stages and not being picked up or even other possibilities.

The IgG is the least accurate test out of all of the tests and that alone positive would most likely not result in a diagnosis.

If symptoms are there though and it is in the family then there is a likely chance that they are in beginning stages.

Even though both my boys are symptomatic (one significantly so), their tests came back negative. I strongly suspect that will change over time.

      Celiac Diagnosis from Bloodwork Only?

      By TraceyG · Posted

      @Wheatwacked thank you for checking in about choline. I do meet me recommended amount on a plant-based diet already, per my nutritionist. Thankfully, I am not intolerant to soy and the cruciferous veggies I enjoy!

      @Wheatwacked thanks for your input. I am fully committed to being gluten-free if I truly have celiac disease.  I suppose my question is more so wondering if that blood test means I definitely have celiac disease. I had one doc look at the results and tell me to ignore them if I don’t have the classic celiac symptoms. The next doc (a few months later, when viewing the same results) said the results were suspicious and might mean gluten sensitivity, but then had her nurse call me later the same day to say I actually have celiac disease based on the results. So my care team seemed a little unsure. It sounds like, from this forum, that the general consensus is any abnormal blood results indicate celiac.

      Hello @TraceyG, welcome.    I know it is hard.  Giving up gluten is like losing a lifelong friend.  But in this case it is not a friend.   Your doctor is your friend and be thankful he is proactive with you. There is no need for the biopsy. Posistive is positive.  Unless you are looking for proof you are not.  Be sure to ask about vitamin and mineral deficiencies tests from the doctor. If you are vegan for the health benefits, reconsider. To get the daily Adequate Intake of Coline (between 500 mg and 3500 mg) you would need to eat 10 cups of cooked brocolli.      If you continue to eat gluten, even small amounts, it will come back on you.  You may experience up to 15 days of withdrawal from the gluten and cravings may be strong.  Gluten activates the opiod receptors, numbing you to the pain.  Gluten is addictive.  Gluten Addiction  Eating a little gluten is like playing with matches.      Recent statistics say 40% of first degree relatives have Celiac Disease, also.

      I would love some opinions. My Tis.Transglut.Ab IgA results were 29.9, with the normal range being 0-14.9.  My PCP said I have celiac disease, based on these results. I asked for a referral to GI, but they can't get me in for 6-9 months! I think I will start gluten-free now, and begin eating gluten again for at least 1 month prior to the biopsy. I know the GI biopsy is the gold standard, but is it reasonable for my PCP to diagnose celiac with just the blood results? I do not have classic celiac symptoms, but have struggled with some mystery peripheral neuropathy and joint pain for years now. Looking at symptoms, I have suspicion for family history of undiagnosed celiac (mom with lactose intolerance, aunts with sjogren's and non-hodgkin lymphoma). I am 39. I don't think I will be someone who can easily and quickly tell the difference in my body from not eating gluten (or getting glutened once gluten-free), so I feel that gluten-free trials will be tricky. If it's relevant, I surely consume smaller amounts of gluten and occasional bread, but my diet is vegan and fairly free of gluten (maybe why bloodwork numbers weren't higher?)

      Please do not consume this if you have celiac disease. One of the ingredients is barley.
