Insight Into Test Results

I was diagnosed with Celiac via blood test about a month ago and went into today for an endoscopy. The notes when I left said it was "normal" but that a biopsy of my small intestine was done and my doctor will call me with those results sometime next week.

My blood test results were as follows:

Deamidated Gliadin Abs, IgA 51.3H (limit 0.0-10.0)

Deamidated Gliadin Abs, IgG 18.1H (limit 0.0-10.0)

T-Transglutaminase IgA >100H (limit 0-3)

T-Transglutaminase IgG 9H (limit 0-5)

Immunoglobin, Qn, Serum 198 mg/DL (limit 70-400)

What I take away from this is that my blood test results were pretty strongly indicating Celiac - is that a fair reading? Does it mean anything to say my endoscopy was "normal" without knowing how my biopsy results turn out?

THanks!

Your blood tests results are strongly positive. You don't need to wait for the biopsy results to start the diet. It is still possible for you to have biopsy results that are positive or even negative. False negatives are not uncommon. Go ahead and start the diet with the blood results you had you need to be on the diet no matter what the results of the biopsy are. You may already have seen some relief of symptoms before you even go back for the results.

Celiac is a fair reading! The new anti-deamidated gliadin peptide test is very good for diagnosing celiac, and that combined with your very high anti-tTG leaves no question.

Normal endoscopy means they saw no inflammation, ulcers, and other GI problems. That's good news. Doctors cannot see celiac disease with the endoscope. They will have done biopsies, but celiac damage can be patchy so there is a chance it can be missed and your biopsy comes back negative. You still need to go on a gluten-free diet, as I'm sure your doctors will tell you if they haven't already.

Thanks. I got the blood test results a month ago and went gluten-free right away. Hard to say if I noticed a difference because I wasn't having serious or even daily symptoms. Celiac runs in my family (dad, aunt and cousin although none have been biopsy-confirmed) so I've been on the lookout for it and after experiencing a variety of minor issues the last couple months (bloating and other digestive issues, fatigue, migraines, mood swings, mild depression...), I asked my regular doctor to test me as part of my regular annual exam. I had been tested at a free screening at the U of C Celiac Center in 2008 and that was negative.

Because of the family history, I originally wasn't going to bother with the endoscopy, but everything I have read seemed to strongly recommend it. When I found a doctor who could get me in right away, that sealed it (some docs I contacted wouldn't be able to get me in until September). He did have me go back to eating gluten between scheduling the endoscopy (last Friday) and the test today, but now that it's done, I am definitely back to gluten-free.

So to my and my doctor's surprise, my biopsy came back totally normal. Any ideas why this could be??? He is going to have me come in for the genetic test now and see what that shows.

For now I am going to stay gluten free, although because I did not have bad or consistent symptoms, it's hard to tell if I am really feeling all that better. Plus, I was off for 2 weeks post-blood test, then back on for a week before the biopsy and now on again for a week.

It's stupid, but after the blood test, I told all my friends and family I had Celiac, everyone knows now and has been very good about trying to help me adjust, I'd feel pretty stupid if it turns out to be a false alarm and I am not really gluten-intolerant after all. My blood test seemed so strongly positive, though, I just don't get how my biopsy could be so normal!

As someone else mentioned above, they can't see the damage done by celiac with the endoscopy. They are just guessing at where to take tissue samples. They may have taken tissue samples of the healthy part of you intestines. OR since you had been of gluten for a month the damage may have healed. There may have not been very much damage to your intestines to begin with. If you caught the celiac fairly soon after your symptoms developed (and it sounds like you did) then you would not have very much damage to the intestine yet. Most people with celiacs suffer for years before they find someone to do tests. You are lucky that you have a family history of it and knew to get tested at the first sign. The blood tests are often false negatives, but very rarely false positive. You were diagnosed with a strongly positive blood test. There's no need to do anymore testing. Really there was no need to do an endoscopy at all. You have celiac disease.

I know it's hard. I went through a denial period myself. But if you keep eating gluten you will do more damage to your intestines leading to malnutriton and possibly cancer on down the road.

False negatives with both blood and biopsy are not uncommon at all. You have 22 ft of small intestine and the damage can be patchy and be missed. I would not bother with the gene testing as that could confuse things even more. Commonly only 2 of the 9 celiac associated genes are tested for and if you don't carry one of those 2 genes you will be told you don't have celiac.

Your blood tests were positive, accept the diagnosis and stay on the diet.

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

      Welcome, @catnapt! The most recent guidelines are the daily consumption of a minimum of 10g of gluten (about the amount found in 4-6 slices of wheat bread) for a minimum of two weeks. But if possible stretching that out even more would enhance the chances of getting valid test results. These guidelines are for those who have been eating gluten free for...

The Dapsone has cleared the rash entirely but I still get quite a bit itching, absolutely nothing to see though. I know its notoriously hard to clear and its still relatively early days for me.  The iodine issue is very interesting. I do eat quite a bit of salt because I have Addison's disease and sodium retention is an issue. I also have autoimmune hypothyroidism, not sure how a low iodine diet would play into that? Because of my Addison's I am totally steroid dependent, I take steroids 4 x daily and cannot mount any defence against inflammation. I need to increase my meds for that. Now that I know what is wrong I can do just that if Im having a bad day. Life is very sweet, just so damn complicated sometimes! Hey ho, onwards. Thank you again for your advice.

      So, essentially all of the nutrition in the food we eat is absorbed through the villous lining of the small bowel. This is the section of the intestinal track that is damaged by celiac disease. This villous lining is composed of billions of finger-like projections that create a huge amount of surface area for absorbing nutrients. For the celiac person, when gluten is consumed, it triggers an autoimmune reaction in this area which, of course, generates inflammation. The antibodies connected with this inflammation is what the celiac blood tests are designed to detect but this inflammation, over time, wears down the finger-like projections of the villous lining. Of course, when this proceeds for an extended period of time, greatly reduces the absorption efficiency of the villous lining and often results in many and various nutrient deficiency-related health issues. Classic examples would be osteoporosis and iron deficiency. But there are many more. Low D3 levels is a well-known celiac-caused nutritional deficiency. So is low B12. All the B vitamins in fact. Magnesium, zinc, etc.  Celiac disease can also cause liver inflammation. You mention elevated ALP levels. Elevated liver enzymes over a period of 13 years was what led to my celiac diagnosis. Within three months of going gluten free my liver enzymes normalized. I had elevated AST and ALT. The development of sensitivities to other food proteins is very common in the celiac population. Most common cross reactive foods are dairy and oats but eggs, soy and corn are also relatively common offenders. Lactose intolerance is also common in the celiac population because of damage to the SB lining.  Eggs when they are scrambled or fried give me a gut ache. But when I poach them, they do not. The steam and heat of poaching causes a hydrolysis process that alters the protein in the egg. They don't bother me in baked goods either so I assume the same process is at work. I bought a plastic poacher on Amazon to make poaching very easy. All this to say that many of the issues you describe could be caused by celiac disease.

      thank you so much for your detailed and extremely helpful reply!! I can say with absolute certainty that the less gluten containing products I've eaten over the past several years, the better I've felt.   I wasn't avoiding gluten, I was avoiding refined grains (and most processed foods) as well as anything that made me feel bad when I ate it. It's the same reason I gave up dairy and eggs- they make me feel ill.  I do have a bit of a sugar addiction lol so a lot of times I wasn't sure if it was the refined grains that I was eating - or the sugar. So from time to time I might have a cookie or something but I've learned how to make wonderful cookies and golden brownies with BEANS!! and no refined sugar - I use date paste instead. Pizza made me so ill- but I thought it was probably the cheese. I gave up pizza and haven't missed it. the one time I tried a slice I felt so bad I knew I'd never touch it again. I stopped eating wheat pasta at least 3 yrs ago- just didn't feel well after eating it. I tried chick pea pasta and a few others and discovered I like the brown rice pasta. I still don't eat a lot of pasta but it's nice for a change when I want something easy. TBH over the years I've wondered sometimes if I might be gluten intolerant but really believed it was not possible for me to have celiac disease. NOW I need to know for sure- because I'm in the middle of a long process of trying to find out why I have a high parathyroid level (NOT the thyroid- but rather the 4 glands that control the calcium balance in your body) I have had a hard time getting my vit D level up, my serum calcium has run on the low side of normal for many years... and now I am losing calcium from my bones and excreting it in my urine (some sort of renal calcium leak) Also have a high ALP since 2014. And now rapidly worsening bone density.  I still do not have a firm diagnosis. Could be secondary HPT (but secondary to what? we need to know) It could be early primary HPT. I am spilling calcium in my urine but is that caused by the high parathyroid hormone or is it the reason my PTH is high>? there are multiple feedback loops for this condition.    so I will keep eating the bread and some wheat germ that does not seem to bother me too much (it hasn't got enough gluten to use just wheat germ)    but I'm curious- if you don't have a strong reaction to a product- like me and wheat germ- does that mean it's ok to eat or is it still causing harm even if you don't have any obvious symptoms? I guess what you are saying about silent celiac makes it likely that you can have no symptoms and still have the harm... but geez! you'd think they'd come up with a way to test for this that didn't require you to consume something that makes you sick! I worry about the complications I've been reading about- different kinds of cancers etc. also wondering- are there degrees of celiac disease?  is there any correlation between symptoms and the amnt of damage to your intestines? I also need a firm diagnosis because I have an identical twin sister ... so if I have celiac, she has it too- or at least the genetic make up for having it. I did have a VERY major stress to my body in 2014-2016 time frame .. lost 50lbs in a short period of time and had severe symptoms from acute protracted withdrawal off an SSRI drug (that I'd been given an unethically high dose of, by a dr who has since lost his license)  Going off the drug was a good thing and in many ways my health improved dramatically- just losing 50lbs was helpful but I also went  off almost a dozen different medications, totally changed my diet and have been doing pretty well except for the past 3-4 yrs when the symptoms related to the parathyroid issue cropped up. It is likely that I had low vit D for some time and that caused me a lot of symptoms. The endo now tells me that low vit D can be caused by celiac disease so I need to know for sure! thank you for all that great and useful information!!!

      Welcome, @catnapt! The most recent guidelines are the daily consumption of a minimum of 10g of gluten (about the amount found in 4-6 slices of wheat bread) for a minimum of two weeks. But if possible stretching that out even more would enhance the chances of getting valid test results. These guidelines are for those who have been eating gluten free for a significant amount of time. It's called the "gluten challenge".  Yes, you can develop celiac disease at any stage of life. There is a genetic component but also a stress trigger that is needed to activate the celiac genes. About 30-40% of the general population possesses the genetic potential to develop celiac disease but only about 1% of the general population actually develop celiac disease. For most with the potential, the triggering stress event doesn't happen. It can be many things but often it is a viral infection. Having said that, it is also the case that many, many people who eventually are diagnosed with celiac disease probably experienced the actual onset years before. Many celiacs are of the "silent" type, meaning that symptoms are largely missing or very minor and get overlooked until damage to the small bowel lining becomes advanced or they develop iron deficiency anemia or some other medical problem associated with celiac disease. Many, many are never diagnosed or are diagnosed later in life because they did not experience classic symptoms. And many physicians are only looking for classic symptoms. We now know that there are over 200 symptoms/medical problems associated with celiac disease but many docs are only looking for things like boating, gas, diarrhea. I certainly understand your concerns about not wanting to damage your body by taking on a gluten challenge. Your other option is to totally commit to gluten free eating and see if your symptoms improve. It can take two years or more for complete healing of the small bowel lining once going gluten free but usually people experience significant improvement well before then. If their is significant improvement in your symptoms when going seriously gluten free, then you likely have your answer. You would either have celiac disease or NCGS (Non Celiac Gluten Sensitivity).
