Dgp Igg Quick Question

does a negative DGP IgG indicate no celiac? all IgA tests are negative but a low total serum IgA which I know means a false negative on the IgA tests but what about the DGP IgG?

thanks!

Sorry to answer a question with a question, did they do any other IgG tests?

A doctor might interpret a negative DGP IgG as no celiac, but as you've probably gleaned from reading around here, false negatives can be common.

Off to read some of your other posts...I don't recall the background info. :unsure:

Ahhh...okay, just saw the test results. As mushroom mentioned in one of your threads, you should ask the doc to run the EMA-IgG and the TtG IgG. There was not enough testing to really rule it out, given the IgA deficiency. All the tests but one were IgA tests and are meaningless.

There are some around here who only had one positive test, the TtG IgG, yet they did have celiac and is showed on their biopsy. I was one whose only positive test was TtG IgG. I'm not biopsy diagnosed, but my doc decided to call it celiac given my symptoms and relief off gluten.

Try to get those other two tests done.

False negatives are possible on all celiac blood tests, particularly in kids. DGP has 90% sensitivity at best so 1 in 10 celiacs will be missed. Celiac is less likely with negative DGP IgG, and low total IgA will not affect the results.

there is no EMA-IgG.

The endomysium test isa manual test where they look for IgA deposits under an electron microscope

I think you have anti-EMA confused with the dermatitis herpetiformis biopsy, Nora. Anti-EMA is an immunofluorescence assay done with standard fluorescence microscopy. The patient's serum is reacted with monkey esophagus at varying titers and then stained with a fluorescent secondary antibody. It can test for either IgG or IgA depending on which secondary antibody is used.

ok, but I have not seen anyone reporting of having had thenEMA IgG done, and someone posted here some years ago there is no EMA IgG, just IgA so I thought so it was

No. It's not new at all. It just uses an IgG rather than IgA specific secondary antibody. That technology has been around for over 20 years.

sometimes they call the tissue transglutamiase test for EMA (maybe because several years ago the EMA was more known than the then new Ttg test) I have seen that sometimes

      Yes, I do think they need a Thiamine supplement at least. Especially since they eat red meat only occasionally. Most fruits and vegetables are not good sources of Thiamine.  Legumes (beans) do contain thiamine.  Fruits and veggies do have some of the other B vitamins, but thiamine B 1 and  Cobalamine B12 are mostly found in meats.  Meat, especially organ meats like liver, are the best sources of Thiamine, B12, and the six other B vitamins and important minerals like iron.   Thiamine has antibacterial and antiviral properties.  Thiamine is important to our immune systems.  We need more thiamine when we're physically ill or injured, when we're under stress emotionally, and when we exercise, especially outside in hot weather.  We need thiamine and other B vitamins like Niacin B 3 to keep our gastrointestinal tract healthy.  We can't store thiamine for very long.  We can get low in thiamine within three days.  Symptoms can appear suddenly when a high carbohydrate diet is consumed.  (Rice and beans are high in carbohydrates.)  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so symptoms can wax and wane depending on what one eats.  The earliest symptoms like fatigue and anxiety are easily contributed to other things or life events and dismissed.   Correcting nutritional deficiencies needs to be done quickly, especially in children, so their growth isn't stunted.  Nutritional deficiencies can affect intelligence.  Vitamin D deficiency can cause short stature and poor bone formation.   Is your son taking anything for the anemia?  Is the anemia caused by B12 or iron deficiency?

      Thank you! That's helpful. My kids eat very little processed food. Tons of fruit, vegetables, cheese, eggs and occasional red meat. We do a lot of rice and bean bowls, stir fry, etc.  Do you think with all the fruits and vegetables they need a vitamin supplement? I feel like their diet is pretty healthy and balanced with very limited processed food. The only processed food they eat regularly is a bowl of Cheerios here and there.  Could shaking legs be a symptom of just a one-time gluten exposure? I guess there's no way to know for sure if they're getting absolutely zero exposure because they do go to school a couple times a week. We do homeschool but my son does a shared school 2x a week and my daughter does a morning Pre-K 3 x a week.  At home our entire house is strictly gluten free and it is extremely rare for us to eat out. If we eat at someone else's house I usually just bring their food. When we have play dates we bring all the snacks, etc. I try to be really careful since they're still growing. They also, of course, catch kids viruses all the time so I  want to make sure I know whether they're just sick or they've had gluten. It can be pretty confusing when they're pretty young to even be explaining their symptoms!

      That is interesting, and it's the first time I heard about the umbilical cord beings used for that test. Thanks for sharing!

      @lizzie42, You're being a good mom, seeking answers for your son.  Cheers! Subclinical thiamine deficiency commonly occurs with anemia.  An outright Thiamine deficiency can be precipitated by the consumption of a high carbohydrate meal.   Symptoms of Thiamine deficiency include feeling shakey or wobbly in the legs, muscle weakness or cramps, as well as aggression and irritability, confusion, mood swings and behavior changes.  Thiamine is essential to the production of neurotransmitters like serotonin and dopamine which keep us calm and rational.   @Jsingh, histamine intolerance is also a symptom of Thiamine deficiency.  Thiamine is needed to prevent mast cells from releasing histamine at the slightest provocation as is seen in histamine intolerance.  Thiamine and the other B vitamins and Vitamin C are needed to clear histamine from the body.  Without sufficient thiamine and other B vitamins to clear it, the histamine builds up.  High histamine levels can change behavior, too.  High histamine levels are found in the brains of patients with schizophrenia.  Thiamine deficiency can also cause extreme hunger or conversely anorexia.   High carbohydrate meals can precipitate thiamine deficiency because additional thiamine is required to process carbohydrates for the body to use as fuel.  The more carbohydrates one eats daily, the more one needs additional thiamine above the RDA.  Thiamine is water soluble, safe and nontoxic even in high doses. Keep in mind that gluten-free processed foods like cookies and such are not required to be fortified and enriched with vitamins and minerals like their gluten containing counterparts are.  Limit processed gluten-free foods.  They are often full of empty calories and unhealthy saturated fats and additives, and are high in histamine or histamine release triggers.  It's time you bought your own vitamins to supplement what is not being absorbed due to malabsorption of Celiac disease.  Benfotiamine is a form of Thiamine that has been shown to improve intestinal health as well as brain function. Do talk to your doctors and dieticians about supplementing with the essential vitamins and minerals while your children are growing up gluten free.  Serve nutritionally dense foods.  Meats and liver are great sources of B vitamins and minerals. Hope this helps!  Keep us posted on your progress!

      Oats naturally contain a protein called avenin, which is similar to the gluten proteins found in wheat, barley, and rye. While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure. You may fall into this category, and eliminating them is the best way to figure this out. Some people substitute gluten-free quinoa flakes for oats if they want a hot cereal substitute. If you are interested in summaries of scientific publications on the topic of oats and celiac disease, we have an entire category dedicated to it which is here: https://www.celiac.com/celiac-disease/oats-and-celiac-disease-are-they-gluten-free/
