Ttg Iga Vs Ttg Igg Results?

Ok when my son was diagnosed with celiac disease a year ago it was the TTG IgA that came back pos at 40 (a very strong pos) The IgG were neg though. The specialist we saw for the biopsy said with just the blood tests alone he was 99% positive William had Celiac because the one he was pos to was the most accurate for it. Well we had our DD tested at the start of this month because she has similar symptoms and the doctors only ran the IgG! This came back neg but I am wondering if this is the same situation as my DS where the IgA may have shown a pos if they had ran it.

Is it worth the pain for my DD to put her back on Gluten and have her blood drawn again for the IgA test to see if it is pos? She does improve on a gluten-free diet this makes me really suspect that she is following in our DS's footsteps...

It all depends if you want a diagnosis or not. It's an all or nothing diet though so if you only plan on taking her "mostly" off of gluten then you should get tested reason being if it is celiac you don't want to be doing that damage.

If her body is doing well on the diet though it tells me there is a problem with gluten and you could always go with that. I mean does it really matter whether she has an official doctors diagnosis? I would just go with how she is reacting to the diet which is obviously good for a reason plus she has a brother with celiac so you know it is in the family.

The tTG IgA is a better test.

I only had the IgA test and scored 40 as well. My mother was diagnosed with celiac disease by a positive biopsy several years before, and I had a positive response to the gluten-free diet. Enough evidence for me. It was too dangerous for me to go back to eating gluten for a biopsy or whatever....I'm out of commission for weeks after consumption. Not fun.

See I would like to have some sort of official diagnosis largly so we know if she can occasionally cheat (if it is just an intollerance) or if she has to be as strict as my DS. She does not have the severe immediate reaction he has, but then again he didn't have it when he was her age either! Now he can lick a cookie and will throw up, she has to eat gluten foods for a few days before the diarhea comes back. I think this might just be because if she does have Celiac it hasn't progressed as far yet with her being younger. But it would be nice to know if she can have a piece of cake at a birthday party when she is older and that she won't have any major damage, or if she needs me to send a cupcake like I do for William.

It would also help keep my DH and our familes from feeding her gluten containing foods just because 'she doesn't have an official diagnosis'... My DH thinks that since she came back neg to everything that she can eat whatever she wants. Of course he isn't the one constantly changing the diarrhea diapers and spending all day with her moaning and crying that her tummy aches either!

I just don't know if it is worth the pain to have her with diarrhea and constantly complaining that her tummy hurts so we can go through a needle poke and blood drain again. But they did RAST tests at the same time to rule out possible food allergies and those all came back neg also! She has an obvious reaction to something she is eating though I just have to figure out what it is! I'm pretty sure on the gluten though because if I take it out of her diet the diarrhea goes away, put it back and it comes back! She has mucus in her stool even on a gluten-free diet though which makes me think there is more in play.

Well celiac is not an allergy so she may have a reaction to gluten but it may not be an allergy. Allergies are IgE reactions and the gluten reactions from celiac are not.

If you want to get her tested then you need to get her eating alot of gluten(equal to 2-3 pieces of bread a day) for about 3 months prior to testing. The longer you wait the harder it will be so if you want to test now is the time.

How old is your daughter?

She is 2 years 2 months... Ugh that much gluten would be hard because she does not like bread and wont even eat regular cereal! That would mean lots of cookies and crackers. lol... And 3 months before testing would put us in the middle of moving which would mean another month or more after we get to our next base to get the Ped there to realize they need to order the test! Just not going to be 'easy' any way I look at it... :(

Testing under 2 years of age can be inaccurate and give false negatives. Was she tested after 2 years?

I am sure you will find out what to do and what will be best for your situation.

The problem with that theory is that an intolerance could be an early sign of celiac, before sufficient damage has been done to the intestines to show up as "celiac". So cheating, even if it's "just an intolerance" at this point, could lead to larger problems in the future. Perhaps keep her gluten-free until after the move, and then try the challenge later?

My son is 2 yr 2 months as well and at 26 months he tested negative for the Celiac Panel but had positive genetic testing. The pediatric GI Dr. said the only way to know is to repeat the panel after 2 months on gluten. No way, this is the first formed stools he has ever had. I dont need anymore testing. the positive dietary response is enough for us. I cant ever imagine putting him through having gluten again. He was sick, pale and malnourished. Thank God I have an answer now and I decided not to have the biopsy or any further bloodwork. Good Luck and you should be commended for your quick response and help youve given your child, some moms miss this and alot of kids arent diagnosed or helped for many years. At least our toddlers are getting help early. Kuddos to you!!

Ok that is a point I had not thought about till just now. I think keeping her gluten-free is just the best idea anyway. Really I see the difference when we take it out of her diet so I know it has some sort of effect... My DH refuses to believe me though! :(

Thanks. See I figured age may still have a play in the testing but knowing that they did the wrong test makes me a little mad. I had to put her back on Gluten for them to do the wrong test! I really think for now at least I will not retest her. I see the change and that is enough for me...

Kind of along the same lines as why I will not be introducing gluten foods to our baby either. She seemed bothered by it when I would eat too many gluten foods so why even take the chance... She has a severe dairy allergy though so we are being really cautious and going through an allergist to start her on solids for fear of any major reactions.

From the words of Dr. Michelle Pietzak, celiac expert and researcher at Children's Hospital LA,

"The recommended dose is 10g of gluten per day for at least 6 months. A slice of bread per day is enough. Some may make antibodiese as soon as three months."

My ds is gluten-free, and I'm not sure he's celiac. I'm celiac, so it's easy for me to keep him on the diet. He's 3 1/2 yrs. I do intend on testing him, likely when he is 5. I want to wait to do the gluten challenge until his brain/body is done with the super-intense growing part of early childhood, and also his immune system is functioning more like an adult's.

Hth,

Merika

      results from 13 day gluten challenge - does this mean I can't have celiac?

      @catnapt, Wheat germ has very little gluten in it. Gluten is the carbohydrate storage protein, what the flour is made from, the fluffy part. Just like with beans, there's the baby plant that will germinate ("germ"-inate) if sprouted, and the bean part is the carbohydrate storage protein. Wheat germ is the baby plant inside a kernel of wheat...

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3. Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C. Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine. Weight...

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      Hi Jane: You may want to try the D3 I now take. I have reactions to fillers and many additives. Sports Research, it is based in the USA and I have had no bad reactions with this brand. The D3 does have coconut oil but it is non GMO, it is Gluten free, Soy free, Soybean free and Safflower oil free. I have a cupboard full of supplements that did not agree...

      Raising you vitamin D will increase absorption of calcium automatically without supplementation of calcium.  A high PTH can be caused by low D causing poor calcium absorption; not insuffient calcium intake.  With low D your body is not absorbing calcium from your food so it steals it from your bones.  Heart has priority over bone. I've been taking 10,000 IU D3 a day since 2015.  My doctor says to continue. To fix my lactose intolerance, lots of lactobacillus from yogurts, and brine fermented pickles and saurkraut and olives.  We lose much of our ability to make lactase endogenosly with maturity but a healthy colony of lactobacillus in our gut excretes lactase in exchange for room and board. The milk protein in grass fed milk does not bother me. It tastes like the milk I grew up on.  If I drink commercial milk I get heartburn at night. Some experts estimate that 90% of us do not eat Adequite Intake of choline.  Beef and eggs are the principle source. Iodine deficiency is a growing concern.  I take 600 mcg a day of Liquid Iodine.  It and NAC have accelerated my healing all over.  Virtually blind in my right eye after starting antihypertensive medication and vision is slowly coming back.  I had to cut out starches because they drove my glucose up into the 200+ range.  I replaced them with Red Bull for the glucose intake with the vitamins, minerals and Taurine needed to process through the mitochodria Krebs Cycle to create ATP.  Went from A1c 13 down to 7.9.  Work in progress. Also take B1,B2,B3,B5,B6. Liquid Iodine, Phosphatidyl Choline, Q10, Selenium, D and DHEA.     Choline supplemented as phosphatidylcholine decreases fasting and postmethionine-loading plasma homocysteine concentrations in healthy men +

Luckily you still have time to do a proper gluten challenge (10 grams of gluten per day for a minimum of two weeks) before your next appointment when you can be retested.

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3.  Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C.  Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine.   Weight gain with a voracious appetite is something I experienced while malnourished.  It's symptomatic of Thiamine B1 deficiency.   Conversely, some people with thiamine deficiency lose their appetite altogether, and suffer from anorexia.  At different periods on my lifelong journey, I suffered this, too.   When the body doesn't have sufficient thiamine to turn food, especially carbohydrates, into energy (for growth and repair), the body rations what little thiamine it has available, and turns the carbs into fat, and stores it mostly in the abdomen.  Consuming a high carbohydrate diet requires additional thiamine to process the carbs into energy.  Simple carbohydrates (sugar, white rice, etc.) don't contain thiamine, so the body easily depletes its stores of Thiamine processing the carbs into fat.  The digestive system communicates with the brain to keep eating in order to consume more thiamine and other nutrients it's not absorbing.   One can have a subclinical thiamine insufficiency for years.  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so the symptoms can wax and wane mysteriously.  Symptoms of Thiamine insufficiency include stunted growth, chronic fatigue, and Gastrointestinal Beriberi (diarrhea, abdominal pain), heart attack, Alzheimer's, stroke, and cancer.   Thiamine improves bone turnover.  Thiamine insufficiency can also affect the thyroid.  The thyroid is important in bone metabolism.  The thyroid also influences hormones, like estrogen and progesterone, and menopause.  Vitamin D, at optimal levels, can act as a hormone and can influence the thyroid, as well as being important to bone health, and regulating the immune system.  Vitamin A is important to bone health, too, and is necessary for intestinal health, as well.   I don't do dairy because I react to Casein, the protein in dairy that resembles gluten and causes a reaction the same as if I'd been exposed to gluten, including high tTg IgA.  I found adding mineral water containing calcium and other minerals helpful in increasing my calcium intake.   Malabsorption of Celiac affects all the vitamins and minerals.  I do hope you'll talk to your doctor and dietician about supplementing all eight B vitamins and the four fat soluble vitamins because they all work together interconnectedly.

I take NAKA Women's Multi full spectrum, and have not felt sick after taking 2 capsules per day -  it is a Canadian company. I buy both from Amazon. I wish you well in your searching, I know how discouraging it all is. Florence.

      highly unlikely  NOTHING and I mean NOTHING else has ever caused me these kinds of symptoms I have no problem with dates, they are a large part of my diet In fact, I eat a very high fiber, very high vegetable and bean diet and have for many years now. It's considered a whole foods plant based or plant forward diet (I do now eat some lean ground turkey but not much) I was off dairy for years but recently had to add back plain yogurt to meet calcium needs that I am not allowed to get from supplements (I have not had any problem with the yogurt)   I eat almost no processed foods. I don't eat out. almost everything I eat, I cook myself I am going to keep a food diary but to be honest, I already know that it's wheat products and also barley that are the problem, which is why I gradually stopped eating and buying them. When I was eating them, like back in early 2024, when I was in the middle of moving and ate out (always had bread or toast or rolls or a sub or pizza) I felt terrible but at that time was so busy and exhausted that I never stopped to think it was the food. Once I was in my new place, I continued to have bread from time to time and had such horrible joint pain that I was preparing for 2 total knee replacements as well as one hip! The surgery could not go forward as I was (and still am) actively losing calcium from my bones. That problem has yet to be properly diagnosed and treated   anyway over time I realized that I felt better when I stopped eating bread. Back at least 3 yrs ago I noticed that regular pasta made me sick so I switched to brown rice pasta and even though it costs a lot more, I really like it.   so gradually I just stopped buying and eating foods with gluten. I stopped getting raisin bran when I was constipated because it made me bloated and it didn't help the constipation any more (used to be a sure bet that it would in the past)   I made cookies and brownies using beans and rolled oats and dates and tahini and I LOVE them and have zero issues eating those I eat 1 or more cans of beans per day easily can eat a pound of broccoli - no problem! Brussels sprouts the same thing.   so yeh it's bread and related foods that are clearly the problem  there is zero doubt in my mind
