Talk to me about the IGA test. I reguested this from our doctor on Emmah but not until after she was gluten-free. Does this test also have to be done when eatting gluten?

Sorry for the the questions

TIA

The blood test are not one of my most informed areas...

But, I guess that would depend on how long Emma has been gluten free. My blood tests were negative after I was gluten free for two months. I did have a positive biopsy when i was dx'd.

If Emma is improving on the diet, you may want to consider not testing (mine cost $1,500) it is quite costly. The bottom line here is that if she is improving and continuing to thrive, your questions have been answered. But that is ALWAYS a parental choice.

Her picture is very sweet.

Chrissy, I'm not sure. I just told the Dr I want her IGA levels done because I heard something about and IGA diffeciency causing negs on the TTG.

I just posted this link on another topic - Open Original Shared Link . It explains pretty thoroughly what the different tests are, how they interact with each other, and how accurate they are. It also talks about how much gluten and for how long you should be eating it before taking the tests. After reading it, you may or may not want to have the tests done.

I know lots of people on this board were using Enterolab which supposedly doesn't need you to be as recently challenged with gluten and also doesn't require blood. You can read up more about them, too, at their website www.enterolab.com. I was thinking of going through them to get the gene test done on my daughter.

If anything would be positive, I think it would be the tTG or the EMA. According to DR. Peter Green's book, these two are the last two to go negative. My son's tTG was still positive after being gluten free for 3 months. Our doctor, Dr. Guandalini at The University of Chicago Celiac Center, said that the tTG's half themselves every two months. So if you start at 50, at 2 months out it's 25, at 4months around 12....and so on. Do check for an IGA deficiency you need to run a total IGA, I think. I would highly recommend Dr. Green's Book. It's all based on actual proven data. You have to be careful on some of those websites. Anyone can start a blog and it's nice to make sure you're dealing with a medical professional. Not to say there isn't a lot of great info out there, but some of it is just opinion, again which is good too. Good luck!

If you are talking about being IgA deficient, the correct test is the total serum IgA. This is not affected by gluten, whereas the other IgA's are.

(I am IgA deficient)

If you are having the other tests done, there are two outcomes:

if she is positive, she definitely has it.

if she is negative, it doesn't mean she doesn't have it, given that she is gluten free.

(Rez, have to agree with you whole heartedly about Dr. Green's book!!!!!!!)

It's called Celiac Disease: A Hidden Epidemic, By Dr. Peter Green. It's hands down the BEST book on the market. It's all fact and very informative. I have read several and thought many were excellent, but as far as accurate, medical information, this is it! I love some of the others for an empathetic feel good read, but when I need the facts, this is where I dig! :)

Good for you, let me know what you think! Have a great night!

Hope you enjoy!

*just a note, this book deals almost exclusively with Celiac, not non-Celiac gluten intolerance. However, many of the chapters would still be applicable (eating gluten-free, dealing with the gluten-free lifestyle, etc).

Ladies, does this book provide information on Dermatitus Herpetiformus? If so, I will endeavour to track it down as I'm in Australia.

Yes. There is a whole chapter on DH.

      how much gluten do I need to eat before blood tests?

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after eating them. If it happens a few times after eating the same foods- I cut back...

      IBS-D vs Celiac

      Welcome to the celiac.com community, @SilkieFairy! You could also have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. They share many of the same symptoms, especially the GI ones. There is no test for NCGS. Celiac disease must first be ruled out.

      how much gluten do I need to eat before blood tests?

      Under the circumstances, your decision to have the testing done on day 14 sounds very reasonable. But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in...

      IBS-D vs Celiac

      After the birth of my daughter nearly 6 years ago, my stools changed. They became thin if they happened to be solid (which was rare) but most of the time it was Bristol #6 (very loose and 6-8x a day). I was on various medications and put it down to that. A few years later I went on this strict "fruit and meat" diet where I just ate meat, fruit, and squash...

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after  eating them.  If it happens a few times after eating the same foods- I cut back or avoid them. for this reason I avoid dairy and eggs.  So far this has worked well for me.  oh, I have some of Bob's Red Mill Mighty Tasty Hot cereal and I love it! it's hard to find but I will be looking for more.  for the next few weeks I'm going to be concentrating on whole fresh fruits and veggies and beans and nuts and seeds. I'll have to find out if grains are truly necessary in our diet. I buy brown rice pasta but only eat that maybe once a month at most. Never liked quinoa. And all the other exotic sounding grains seem to be time consuming to prepare. Something to look at later. I love beans and to me they provide the heft and calories that make me feel full for a lot longer than a big bowl of broccoli or other veggies. I can't even tolerate the plant milks right now.  I have reached out to the endo for guidance regarding calcium intake - she wants me to consume 1000mgs from food daily and I'm not able to get to more than 600mgs right now.  not supposed to use a supplement until after my next round of testing for hyperparathyroidism.   thanks again- you seem to know quite a bit about celiac.

But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in hospitals or institutional care and I'm guessing your physician would be willing to grant you a diagnosis of gluten sensitivity (NCGS) even if your celiac testing comes up negative. Also, you need to be aware that oats (even gluten free oats) is a common cross reactor in the celiac community. Oat protein (avenin) is similar to gluten. You might want to look at some other gluten free hot  breakfast cereal alternatives.

      IBS-D vs Celiac

      After the birth of my daughter nearly 6 years ago, my stools changed. They became thin if they happened to be solid (which was rare) but most of the time it was Bristol #6 (very loose and 6-8x a day). I was on various medications and put it down to that. A few years later I went on this strict "fruit and meat" diet where I just ate meat, fruit, and squash vegetables. I noticed my stools were suddenly formed, if a bit narrow. I knew then that the diarrhea was probably food related not medication related. I tried following the fodmap diet but honestly it was just too complicated, I just lived with pooping 8x a day and wondering how I'd ever get and keep a job once my children were in school.  This past December I got my yearly bloodwork and my triglycerides were high. I looked into Dr. William Davis (wheat belly author) and he recommended going off wheat and other grains. This is the first time in my life I was reading labels to make sure there was no wheat. Within 2 weeks, not only were my stools formed and firm but I was only pooping twice a day, beautiful formed Bristol #4.  Dr. Davis allows some legumes, so I went ahead and added red lentils and beans. Nervous that the diarrhea would come back if I had IBS-D. Not only did it not come back, it just made my stools even bigger and beautiful. Still formed just with a lot more width and bulk. I've also been eating a lot of plant food like tofu, mushrooms, bell peppers, hummus etc which I thought was the cause of my diarrhea before and still, my stools are formed. In January I ran a genetics test because I knew you had to have the genes for celiac. The report came back with  DQ 2.2 plus other markers that I guess are necessary in order for it to be possible to have celiac. Apparently DQ 2.2 is the "rarer" kind but based on my report it's genetically possible for me to have celiac.  I know the next step is to bring gluten back so I can get testing but I am just not wanting to do that. After suffering with diarrhea for years I can't bring myself to do it right now. So that is where I am!
