Help Interpreting My Lab Results? (updated)

Hello! I'm a new member, 39 years old, just figuring out based on my symptoms through research that I may have Celiac Disease. I took an Everlywell screening at home last week and yesterday had a Celiac panel done at my doctor's office. The results came in today. Are these numbers a pretty sure sign that I have Celiac? My doctor hasn't reviewed the results of the lab yet but I know these are all high. I'm just so worried that I've done so much damage to my body. My symptoms have been pretty mild but are becoming more noticeable over the last year. I just hope I can repair what damage has been done. This is all so new to me. Thank you for any information.

Gliadin Deaminated Antibody IgA - 21.0

Gliadin Deaminated Antibody IgG - 19.0

Tissue Transglutaminase IgA Ab - 128.0

Tissue Transglutaminase IgG - 27.0

Immunoglobulin A (IgA) - 167.0

Welcome to the forum, @Jessica H!

We can't comment as you did not include the reference ranges for the various tests and there are not yet industry standards for the various celiac antibody tests that are available. Each lab creates the tests a little differently and uses their own scales. So, can you repost the info but with the reference ranges this time?

Sorry about that, I just reposted with the reference ranges. I clearly don't know what I'm doing! : )

The < value is the limit of normal. The last one, Immunoglobulin A (IgA) is not a celiac antibody test per se but what we call "total IGA" which is looking for IGA deficiency. If a person is IGA deficient, their IGA celiac antibody test scores will be artificially low which can result in false negatives. Total IGA "normal" is given as a range rather than a less than.

Yes, all your test scores point to celiac disease. I think this is the first time I have ever seen all positives on a full celiac panel. But then, seldom do do physicians order a full celiac panel. Many or most will only order the TTG-IGA. By the way, your score for that one at 128 far exceeds 10x the upper limit of normal. In Europe, many doctors would grant you an official diagnosis of celiac disease on that alone. And diagnosing on high TTG-IGA scores alone is very slowly gaining traction in the USA.

But don't make the mistake of starting a gluten free diet until all testing for celiac is done. It is likely that your doctor may refer you for an endoscopy/biopsy to confirm the results of the antibody testing and you don't want to begin the gluten free diet until that is over or you may invalidate the outcome.

Thanks for the reply. I was assuming my score was pretty high and I was probably looking at a diagnosis. Do you think being 10x the upper limit signifies anything I should be more concerned about? I know they don’t use ‘stages’ anymore but would this indicate it’s pretty bad or not necessarily? I just don’t know how to interpret what that number could mean. It’s all kind of scary when I see how high it is compared to the norm.

They do use stages but only when evaluated the damage done to the villi of the small bowel after looking at the biopsy samples. I'm referring to the "Marsh" scale. As far as I know, "stages" has never been applied to blood antibody test scores.

It would not be appropriate to assign stages based on antibody scores as the damage done would depend not only the antibody levels in the blood at the time of testing but the duration of it and the intensity of it over time since the onset. And those are all very subjective things.

I understand your concern about irreparable damage done to body systems but you are fairly young and your body still has very good rejuvenation powers. Is there laboratory or medical evidence that anything other than the lining of your small bowel has been compromised yet? Do you have bone demineralization for instance or unexplained dental decay or neurological deficits? Stuff like that? It took 13 years to arrive at a diagnosis of celiac disease in my case from the first laboratory evidence (elevated liver enzymes) of onset and by that time I had developed osteopenia. I was 50 or 51 at the age of diagnosis.

No other testing has been done at this point, though I wonder if my diagnosis will prompt that. My main symptoms have been bowel related and I’ve had severe migraines for several years now but I’ve been seeing a neurologist for that and have it under control, though I now wonder if the migraines have been a symptom of Celiac all along.

Migraines are a recognized symptom of celiac disease. The incidence of it is higher in the celiac community than in the general population. It is one of mine.

Well, keep us posted. Do you have a follow up appointment scheduled yet? Again, let me stress that it is important to not begin the gluten free diet or even a reduced gluten diet until all testing related to celiac diagnosis is complete.

I've got my initial appointment with a gastro for a month from now and then I'm assuming we'll schedule my endoscopy from there for a confirmation of the diagnosis. I feel like it's pretty clear since my results are 18x the normal range but I know an endoscopy is the standard. I'll definitely post how that goes.

How are you doing with your osteopenia since your diagnosis? Have you found any relief? Thank you for the support and answering my questions. This is all kind of overwhelming.

Not sure about the state of my osteopenia. I haven't had a DEXA scan done since about age 50 and I'm now 74. No fractures, though. I have significant curvature of the upper spine (kyphosis) but that was well along by the time I was diagnosed with celiac disease almost 25 years ago. So, I think it may have been arrested at least.

Hi trents, just an update to my post, I had my follow up with my gastroenterologist. Scheduled my endoscopy for July 17th and got my biopsy results back July 28th. I have my official diagnosis now and I do in fact have Celiac disease. I'm slowly starting to switch my diet over to completely gluten free. My goal is to be completely gluten free after Christmas this year. I know I should be stopping completely now, but I am have a really hard time with change so my doctor told me I could do this gradually if it was easier for me. Now I know though and can make myself better with simple steps, no medication and have peace of mind knowing what I have is not the end of the world. Thanks again for your support. I've learned a lot over the last couple of months.

Cutting out major sources of gluten in one's diet is pretty easy. It's the hidden sources where it shows up in products you would never expect to find wheat in (like soy sauce and Campbell's tomato soup, most canned soups, many pork n' bean products), medications, supplements, oral hygiene products, etc. that are the things that trip you up. And then there is eating out in restaurants where you order something that should be gluten free but it's cooked along with things that have wheat. Eating out is the biggest threat to eating gluten free. Achieving a truly gluten free diet involves a real learning curve.

It concerns me that you seem to want to ease into this gradually. That just sounds too casual to me and screams of not taking this seriously. The longer you put off achieving a truly gluten-free life style, the longer your body will continue to be harmed. In your first post in your thread you seemed concerned about harm that already might have been done. Now you seem to be singing a different tune.

      Food Allergies

      By Ginger38 · Posted

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      Bread choice for a newbie

      By Kris2093u4 · Posted

      Geography makes a difference.  I'm in the West and Trader Joe's gluten-free bread tastes great and is a better price than most gluten-free breads sold elsewhere in my area.

      7yo struggling!

      By JForman · Posted

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?

      My mo,ther married a bread making when I was 4

      By the time I was 5 I had my first auto0immune disorder, Migraine headaches, with auras to blind me, and vomiting, sensitivity to light and sound. I was 5 years old, and my stepfather would have pizza night, milling his own flour, making thick cheesy gluten pizza, that I would eat and the next day, I would have serious migraines, and my mother & stepfather did nothing about my medical problems. When I was 17 in my first year at college, I was diagnosed with my 2nd known auto-immune disorder, Meniere's disease. I was a elite athlete, a swimmer, and soccer player. And once again my parents didn't think anything of understanding why I had a disorder only older people get. Now after my mother passed from Alzheimer's disease she also suffered with living with gluten. She had a rash for 30 years that nobody could diagnose. She was itchy for 45 years total. My brother had a encapsulated virus explodes in his spleen and when this happened his entire intestines were covered with adhesions, scar tissue and he almost lost his life. He has 5 daughters, and when I finally was diagnosed after being pregnant and my body went into a cytokine storm, I lost my chance to have children, I ended up having Hashimoto's disease, Degenerative Disc disease, and my body started to shut down during my first trimester. I am 6ft tall and got down to 119lbs. My husband and I went to a special immunologist in Terrace, California. They took 17 vials of blood as we flew there for a day and returned home that evening. In 3 weeks, we had the answer, I have Celiac disease. Once this was known, only my father and husband made efforts to change their way of feeding me. At the family cabin, my stepfather & mother were more worried that I would ruin Thanksgiving Dinner. It wasn't until one of my cousins was diagnosed with Celiac disease. They finally looked into getting Gluten Free flour and taking measures to limit "gluten" in meals. He did nothing but ask for me to pay for my own food and wi-fi when I came to the cabin to stay after our house burned down. When he informed my mother, they proceeding to get into a physical fight and she ended up with a black eye. The is just more trauma for me. Sam had no interest in telling the truth about what he wanted. He lied to my mother that he had asked my husband if I could pay for "food" when he asked Geoffrey if I had money to pay for my wi-fi. My mother hates when he spends so much time on the computer so he lied and said I could pay for my own food. I will remind you I weighed 119lbs at this time. (At 6ft) that is a very sick looking person. Neither parent was worried about my weight, they just fought about how cheap my stepfather was. As my mother was diagnosed with Alzheimer's disease in 2014. He had her sign over the will to a trust and added his children. He had no testimonial capacity at the time, so she signed without proper papers. Making this Trust null and void. When I gave my brother my childhood home, my mother stated I would be getting an equal part of inheritance to the house on Race. It currently worth 2.0 million $. I got nothing, and my stepfather has since disowned me b/c of my claim and he knows that my mother would never have left it uneven between my biological brother and myself. She sat me and my husband down, as we lived at the Race Street house and treated and took care of it as our own. My brother took over b/c he was going through a horrific divorce and needed a home so he could get a better custody deal with his soon to be ex-wife who was a Assist DA for Denver. She used the girls against him, and he & I were the primary caregivers. We, Judd and I spent the most time with them pre the divorce. Once Judd moved into the house, he threw all of my mother, grandmother and my family heirlooms out to the Goodwill. Nobody told my mother about this as she was going through cancer treatment and had Alzheimer's disease in her mother and her sister. My stepfather and biological brother took advantage of this matter, as I called a "family council" that my brother just never could make it to at the last moment. All of the furnishing, kitchen ware, everything was in the house my brother just moved into. He had had 2 weddings, I chose to elope b/c my stepfather ruined my brother's first wedding by talking about his relationship with my brother in front of my dad and his entire family, insulting him and having my grandfather leave the ceremony. It was a disaster. My stepfather just plays dumb and blames my father for the slight. I was the only child not to have a wedding. So, my mother and stepfather never had to pay for a thing. My mother had had an agreement with my father he'd pay for college and all medical issues with their kids, myself and Judd. So truly my mother never had to pay for anything big for me in her entire life. I am looking for anyone that has had a similar story, where they grew up in a household that had a baker that regularly milled flour and ate gluten. What happened to you? DId you suffer from different auto-immune diseases b/c of living with a baker using "gluten" Please let me know. I have been looking into legal ways to get my stepfather to give me what my mother had promised, and he erased. Thank you for listening to my story. Jane Donnelly

      Blood results

      By trents · Posted

      Possibly gluten withdrawal. Lot's of info on the internet about it. Somewhat controversial but apparently gluten plugs into the same neuro sensors as opiates do and some people get a similar type withdrawal as they do when quitting opiates. Another issue is that gluten-free facsimile flours are not fortified with vitamins and minerals as is wheat flour (in the U.S. at least) so when the switch is made to gluten-free facsimile foods, especially if a lot of processed gluten-free foods are being used as substitutes, vitamin and mineral deficiencies can result. There is also the possibility that she has picked up a virus or some but that is totally unrelated to going gluten-free.
