After positive gene test, what bloodwork to order?

I have two daughters that are symptomatic and both have tested positive for high risk celiac genes. They were both gluten free by the time they were tested, so neither have officially been diagnosed celiac. I had the rest of my family gene tested and discovered that I am double DQ7, and my husband is DQ2.2, 2.5. We've decided to all go gluten free since all of our kids are 2.5 cis or trans. They have various health issues. I will get into more details in a future post. I have been gluten free for a few years now, but my husband isn't. I'd like him to get bloodwork before he gives up gluten. Besides a full celiac panel, what other tests should he request?

-Tissue Transglutaminase (tTG) IgA and (tTG) IgG
-Deamidated Gliadin Peptide (DGP) IgA and (DGP) IgG
-EMA IgA 
-total serum IgA and IgG (control test)
-AGA IGA and AGA IgG - older and less reliable tests largely replace by the DGP tests
 
-endoscopic biopsy - make sure at least 6 samples are taken
 
VERY IMPORTANT:  Keep eating gluten daily until ALL testing is complete or the tests can be inaccurate.

Thank you, that is very helpful.  I was wondering, if we should also ask for thyroid or deficiency tests, but I suppose that would come after a positive celiac test.

I will keep you posted. We have six kids with various health issues and my suspicions are finally being confirmed. It was worth getting the gene testing done just to stop second guessing myself.

You do know that 30% of the poulation carries the celiac genes, right?  And only a tiny amount actually go on to develop celiac disease?  The gene test is usually used only to rule out celiac disease -- not to diagnose.  So, your family has the slight risk of developing celiac disease, but without actual antibody testing or intestinal biopsies, you will never know for sure.   It is a good idea to get your husband tested now if he has symptoms and because he is consuming gluten daily.  

If you suspect thyroid issues, your doctor can order thyroid tests.  Only as few celiac patients have thyroid disorders.  Normal CBC blood tests ordered during a regular check-up for anybody (with or without celiac disease) can rule out anemia and other issues.  

I am assuming that you and your two daughters are now symptom free since being gluten free?.  How old are your kids?  A celiac disease diagnosis is VERY helpful if your kids go to school.

      Help with genetic testing

      By Scott Adams · Posted

      The genetic testing results you provided indicate that your child carries two copies of the HLA-DQ2.5 beta chain (DQ Beta 1 *02:01, *02:01), which is a high-risk genetic marker for celiac disease. However, the alpha chain (DQ Alpha 1 *05:01, *05) is only partially present, as HLA-DQ2.5 typically requires the alpha chain *05:01 paired with the beta chain 02:01. Since your child has two copies of the beta chain (02:01) but only one full *05:01 alpha allele (the other appears truncated as *05), this suggests they are heterozygous for HLA-DQ2.5 rather than homozygous. The term "permissive for celiac disease" means your child has genetic susceptibility but not necessarily the highest-risk genotype (homozygous DQ2.5). Since celiac disease development also depends on environmental triggers and other factors, further testing (such as antibody screening or biopsy) may be needed to confirm a diagnosis. Consulting a genetic counselor or gastroenterologist can help clarify these results and next steps.

      Finding gluten free ingredients

      As my doctor said, you don't have to eat breakfast food for breakfast.  I may have a leftover piece of chicken and left over squash or eggs or I am actually more likely to skip breakfast as I do intermittent fasting.  In that case I eat lunch around 11:30 and have some guacamole and a salad with chicken or tuna.  For dinner I have pork, shrimp, chicken, lamb, or turkey with half a baked sweet potato and some broccoli, green beans, beets, carrots or cauliflower.  I do not eat any grains on the advice of my doctor.  I do not eat commercially processed products, even if they say they are gluten-free.  I make Warrior Bread every few weeks.  It has no yeast and contains almond flour and dried sweet potato.  Very tasty too.  A good book to help in this regard is No Grain, No Pain by Peter Osborne.  Thankfully, I can eat coconut and nuts and use those flours in baking and also use nut milks in cooking.  Since I am allergic to chocolate and vanilla, lemon is my go to flavor for something sweet.  My migraines totally disappeared once I went gluten and casein free.  I can occasionally eat certain high fat cheeses that are low in casein, as well as grass fed butter.  I use lots of Organic Olive and Avocado oil. The problems I thought I had with nightshades went away when I went fully organic.  And, the rest of my issues went away by avoiding the foods I tested positive to as well as avoiding all grains. I will be the first one to say that it is a very expensive way of eating, but thankfully we can afford to eat that way.  The good news is that I take no prescription meds at age 72.  At 54 before diagnosis, I was a mess and on a boatload of pharmaceuticals.

      With that many foods removed from your diet, what do you eat?  I also have histamine issues and migraines so that takes out certain trigger foods and high histamine vegetables.  Have allergies to coconut and issues with nuts so those are out.  I'm beginning to think I may have to remove dairy and some of the grains beyond wheat to get allergies under control.  Just having so many issues figuring out what to make at meal times.  What's a typical breakfast look like for you?  Thanks.

      @Healthforme, No prescription needed for thiamine hydrochloride, Benfotiamine, and TTFD (Tetrahydrofurfuryl Disulfide).  They are available over the counter.   Thiamine Mononitrate is not recommended because the body doesn't absorb or utilize it well.
