OK, so I went to see a gi today and showed him my original test result. I had an endomysial ab (iga) screen and it came back positive. There was also a titer done which came back at 1:5 (I have no idea what that means). He told me that my gp ordered the wrong test and that the endomysial ab screen is not an accurate test.

He explained the different ways to check for celiac and the different tests they do (which I already knew all about). He gave me the option of having a Tissue Transglutaminase AB IGA/IGG and an IGA Level and said that if the numbers are high enough, he wouldn't even bother doing the biopsy. He also said I could go with the genetic test, but that its a lot more costly. I asked him if he could give me an order for both and I would decide which test I wanted, and he did. So here are my questions for you:

1. What is the endomysial ab screen? Is it an outdated test? From what I understand it is 100% specific to celiac, but he doesn't seem to think so.

2. Based on the fact that the endomysial screen came back positive, would you do the genetic test or the other tests (TTG AB IGA/IGG and IGA)? I have read that there is a lot of false positives with those.

3. Should I do both tests? If so, has anyone had experience with their insurance co. not paying for the genetic test? I figured that the positive endomysal screen would warrant a genetic test, but he said not for a gastroenetrologist, and that they may not pay for it. I would love to just go ahead and do both tests but I'm concerned about the insurance kicking back the genetic test and having to pay for it out of pocket. I have an HSA and my deductible is met so everything is covered at 100%.

Thank you so much for your help and advice! I have gotten so much more from this forum than any other site I've gone to.

Your insurance should pay for the Iga(checked to see if you are deficient or not which helps to validate the other tests) and the TTG Iga/Igg. You will have to check with your policy on the genetic testing. Mine won't pay for genetic testing at all. I found out when my youngest son was 14 mo old and being screened genetically for LAD (leukocyte adhesion deficiency). I had already taken him in and they drew his blood, when the lady from my work called me and told me they would not pay. She had the nerve to stop the lab from sending his blood to Mayo Clinic in in MN (the only lab at the time that performed the test) until she talked to me. I did not care if they paid for that test, we needed to know if he had it because it would have inpacted his care greatly. As a result I had to take him back in and get stuck again and I was furious. Anyway, I have not had myself genetic tested or my two boys because of the ins. not paying. For me it won't change anything (I am curious though) and I will annually have the boys screened or checked sooner if symptoms should arise. It probably would not hurt, but it's up to you, to have the rest of the pannel done. I didn't and wish I did so I would have a baseline to go on. I only had the TTG done. If you do decide you should have the anti gliadin antibodies done also.

It discusses the different tests used and why, etc. Maybe it will help.

I'd go for the blood panels first, especially since they're typically covered under medical insurance. Then if you get what you feel is a false negative, you can always go to the genetic testing to see if you even carry the gene.

Also, many celiacs never get a confirmed medical diagnosis -- they just, usually out of desperation and years of misdiagnosis, went on a gluten free diet because many of their symptoms led them there, and all their problems disappeared. For many, that is enough of a diagnosis. It is an individual thing.

Thank you. You make a lot of sense. I'm sorry about what happened to your little guy. That would make me furious too!!! Yes, whatever the tests say, it will not change anything for me. The proof for me was going gluten-free for 3 weeks and thats all I need to know. I'm more interested (and of course curious) in order to test my boys so they don't spend years trying to figure out what is wrong with them like I did. I suspect my dad and his mom had it and so thats why I'm being so adamant about being tested, even though the doctors think I'm a nut. I will have the rest of the panel done, since my ins. will pay 100% and I'll ask about the genetic test. Thanks again for your advice.

Yes, you are right. I have made up my mind that no matter what these tests say, as soon as I go to the lab, I am gluten free! That will have to be enough of a diagnosis for me. I am at the point of desperation and years of misdiagnosis, and as someone else put it who responded to one of my previous points, no matter what these doctors say, I don't need their permission to go gluten free. So yes, I will go ahead and have the panel done first and do the genetic afterwards. Thank you for the link you sent me too. It did answer a lot of questions. I was mainly confused because I thought the endomysial screen was 100% specific to celiac, but I will get the rest of them done too as that will hopefully paint a better picture. Thanks again!

      Toothpaste question.

      By RDLiberty · Posted

      So, I've been using a gluten free labeled toothpaste since being diagnosed with celiac. No big deal, the toothpaste seems to work. Question is, I just realized it contains hydrated silica.  Now, I've heard that silicon dioxide can cause issues in some people with celiac (was that ever confirmed though?), so to be safe, I cut it out of my diet entirely. But, as I understand it, hydrated silica is related to silicon dioxide. Is that something to worry about, or is the hydrated form not known to cause issues like the silicon dioxide form?  I've never seen it in food, but nearly every toothpaste I look at contains hydrated silica?  Issue or not?  Any scientific research (Not opinion pieces, not health bloggers, you get my gist), but actual science, that says it's an issue? I have a hard time believing 99% of what I read on random internet searches.    Thanks so much, Renee.

      How Come Gluten Didnt Bother Me In Italy

      By Gigi2025 · Posted

      Since 2015 we've spent extensive time in Italy and I've been able to eat their wheat products without incident. Initially, I was practically starving thinking foods in Sicily were not gluten-free.  An Italian friend who had lived in the US for over 20 years said she had celiac/gluten-free friends from the US who could eat Italian wheat products without problems. Hesitantly, I tried little by little without issues.  A few years later at a market, I asked a bread vendor if they had gluten-free loaves. Turns out she had lived in LA, said groups believe it's not the gluten that's causing our bodies harm, but potassium bromate; these groups have been trying to ban it.  Bromines and other halogens wreaks havoc to our endocrine system and, more specifically, our thyroids and immune systems. When bromines are ingested/absorbed into the body, it displaces iodine causing other health issues. Potassium bromate is a powerful oxidizing agent (dough 'conditioner') that chemically changes flour to enhance elasticity, bleaches the dough, and ages the flour much faster than open air.   Shortly thereafter while visiting friends in California, one family said they had gone gluten-free and the difference was incredible. The reason they choose this path was due them (a biologist/chemist/agriculturist scientist) having to write a portion of a paper about a certain product for the company he worked. Another company's scientist was directed to write the other portion. All was confidential, they weren't allowed to know the other company/employee.  After the research, they learned gluten was being removed from wheat, sent elsewhere, returned in large congealed blocks resembling tofu, and then added to wheat products. Potassium bromate has been banned for use in Europe, China, and other countries, but not in the US. Then we have the issues of shelf preservatives and stabilizers. What are we eating?  Why? We spend long periods of time in Italy and all has been good.  We just returned from an extended time in Greece;  no issues there either.  There is a man there we learned about on a travel show about Greece who walks the hills, picking herbs, pods, etc.  He is a very learned scholar, taught at the university level in Melbourne. It took a few days to locate him, but were finally successful. He too, is concerned about the additives and preservatives in American food (many of his customers are Americans, haven't been in the best of health, and have become healthier after visiting him). He suggested taking a food product from the US and the same product in Europe, and compare the different ingredients. Then ask why these things are being allowed in the US by the 'watch dog' of our foods and drugs. It would be amuzing if it weren't tragic. I'm presently looking for flour from Europe that I can make my own bread and pasta as the gluten-free bread is now $7.99 a (small) loaf.  BTW, studies are showing that many gluten-free individuals are becoming diabetic. My guess is because the gluten-free products are high in carbs. This is only my experience and opinion garnished by my personal research.  I hope it helps.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By knitty kitty · Posted

      Symptoms that get worse if you don't supplement is a sign of malabsorption, possibly due to Celiac disease. Blood tests for nutritional deficiencies are not very accurate, and should be done when you have been off of supplements for eight to twelve weeks, otherwise the vitamin supplements you've taken will be measured.  The blood circulation system is a transportation system.  It transports the vitamins you've absorbed around the body, but blood tests don't give an accurate picture of the vitamin and mineral stores inside organs and tissues where they are actually used.  You can have "normal" blood levels but still have deficiencies.  This is because the brain demands stored nutrients be put into the blood stream to supply important organs, like the brain and heart, while other organs do without.   If you are taking Thiamine Mononitrate in your supplements, you are probably low in thiamine.  Thiamine Mononitrate is used in many supplements because it won't break down sitting on a shelf.  This also means Thiamine Mononitrate is difficult for the body to utilize.  Only thirty percent of Thiamine Mononitrate on the label is absorbed and even less is able to be utilized by the body.  A different form of Thiamine called Benfotiamine has been shown to promote intestinal healing.   Talk to your doctor about doing a genetic test to look for Celiac markers.   I'm concerned that if you do a gluten challenge (10 grams of gluten per day for a minimum off two weeks) in your weakened state, the nutritional deficiencies will become worse and possibly life threatening.

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By ElisaAllergiesgluten · Posted

      Hello, good afternoon!   I apologize, I didn’t see a notification and I’m just reading this. Thank you so much for sharing your thoughts and the link. Yes you are absolutely right, even so trying to get a response from them has been extremely difficult. They don’t answer but I will your practice of “guilty until proven innocent.”   I like and have a sense of trust here in this website, everyone is honest and thoughts are raw. The mutual understanding is amazing!   thank you Scott!
