Confusing Blood Tests


Klo123

Recommended Posts

Klo123 Newbie

I recently had my 6 year old daughter tested for Celiac due to family history (myself, my sister, and my uncle) and her constant complaints of her stomach aching as well as some fatigue (she would sleep for 13+ hours once a week or so). Her blood tests results are listed below:

Gliadin IGG 13.7 (<10 is normal according to lab) POSITIVE

Gliadin IGA 0.9 (<5 is normal) NEGATIVE

TTG IGG 7.1 (6-9 is a weak positive) POSITIVE

TTG IGA 1.6 (<4 is negative) NEGATIVE

Both IGG were positive and both IGA were negative. Her regular pediatrician said yes she has it, so we started her on a gluten free diet. It has been less than a week so it is hard to tell if it is working. We DO NOT want to do a biopsy on her. I have asked for a referral to a GI, but I know she will have to be back on gluten before going. I guess I was just wondering if anyone could shed some light on the confusing blood tests. Does it seem like she has? Why are her IGA levels so low?

It may be that she's IgA deficient. They could test total IgA and tell you for sure.

That is quite possible, did they do a total IGA?

Also if you are going to do more testing you need to keep her on gluten. If you are not going to biopsy then go ahead and get her on the diet strictly but keep in mind that when she gets to the GI any tests he does will be negative if she is on the diet already.

Also with those positive results it is a good idea to have everyone in the family screened.

      Definitely worth speaking to your gastroenterologist about this. My own told me that by using Gaviscon a barrier forms over the contents of the stomach and stops gas and acid irritating the throat.  In fact, he said to me that because I found relief using Gaviscon that was a very clear indicator that reflux was the cause of that particular issue.   A wedge pillow will really help with this - or raising the top bed legs with bricks.

      I did get the pneumonia vaccine about 4 years ago. I had this amazing allergist who did all those vitamin deficiencies test and told to get that vaccine. Unfortunately she retired.  I haven’t been to an allergist in a few years,  I’m not sure what my levels are now. I did have a pulmonologist who wasn’t concern and said I seemed fine to him that I was young etc. But yes I think I should at the very least get a different opinion. Thank you for your reply

      Yes I do have acid reflux. I’m not on anything for it at the moment. I sometimes wonder if that’s what it could be because I get heart burn every night. I may revisit my gastrointestinal doctor again. Thanks for the reply

      Hi @HelloFlowersGoodbyeFlour I wonder if you suffer from reflux, as if you do, you may find it could also be irritating your airways.  I shall explain: I have to use a blue inhaler from time to time, and it seems to be related to reflux.  Never had any trouble before my coeliac diagnosis, the reflux seemed to be something that developed following a holiday to France in 2019, where I had been exposed to gluten.    The reflux continued into the autumn and winter, my throat itched to begin with, particularly after meals, but it then that feeling of irritation seemed to spread to my lungs.  I even found it difficult to breathe on occasion. What stopped it in its tracks was using a wedge pillow at night, following a reflux diet (you can find them online), not eating 2-4 hours before bed and also having a dose of Gaviscon Advanced at night, which forms a barrier so that acid/food can't go back up your esophagus.  The throat irritation faded, and then I found it easier to breathe again. Just mentioning in case it could be a contributing factor.

      Since initially getting your D checked a few years ago, has it since rebounded to normal levels? Sounds like at some point you got it checked again.
