Gluten For Bloodwork

Clearbelle

Hi All,

I am new here. I was just given a prescription for bloodwork to test for celiac disease by my doctor - only for the first time did I see on this board that you should be eating gluten for accurate results - how important is this? I have been gluten free for almost 1 month. I don't want to cause any undue symptoms etc either - but would like a confirmation of my condition for all types of reasons. I also have autoimmune thyroid disease and many of my symptoms don't make sense for GD - but they do for celiac disease -so I would like to know for sure so that I can ensure that I am taking care of myself all around. I don't plan on starting to eat gluten again regardless - but would just like to know. What do you all recommend. Is there a chance that i could still test positive even though I have been gluten free.

Also, how long does it usually take for symptoms to dissapate -while I have had a degree of relief since giving up gluten I do still have many symptoms - does this usually take a while?

Lasty, a rather bizarre question - but I have been having issues with an itchy nipple for over a year now - had a biopsy which showed some form of inflammation - dermitis? Could this be associated with celiac disease?

Thanks, C

I am sure you will read all about how it is inportant to be eating Gluten for the blood work! If you haven't been real strict then you might be ok, I went back on for about a week after a low gluten diet for a couple of weeks, and tests showed inconclusive. (I think) Still there are antibodies which will hang around for months after gluten-free. Anyhow, in regards to your nipples, I have had horible nipple troubles over the years but it has been related to breastfeeding. As long as I am BF I have sore nipples and when I quit they clear up. I have wondered too if there was a connection!

A month on a gluten-free diet is pretty likely to skew your results. You should be eating a gluten-free diet (of about 3 slices of bread a day) for about 3 months prior to testing to have reasonable confidence of not getting a false negative, though it's no guarnatee. Recovery of symptoms can take a number of months, once you get every last ounce of gluten out of your life.

      Hey there, have you been tested for allergies? You may not only have celiac disease but be allergic. I have celiac disease and am allergic to Barley, wheat and rye.

      I have osteopenia and have cracked three vertebrae.  Niacin is connected to osteoporosis! Do talk to your nutritionist and doctor about supplementing with B vitamins.  Blood tests don't reveal the amount of vitamins stored inside cells.  The blood is a transportation system and can reflect vitamins absorbed from food eaten in the previous twenty-four to forty-eight hours.  Those "normal limits" are based on minimum amounts required to prevent disease, not levels for optimal health.   Keep us posted on your progress.   B Vitamins: Functions and Uses in Medicine https://pmc.ncbi.nlm.nih.gov/articles/PMC9662251/ Association of dietary niacin intake with osteoporosis in the postmenopausal women in the US: NHANES 2007–2018 https://pmc.ncbi.nlm.nih.gov/articles/PMC11835798/ Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/   Nutritional Imbalances in Adult Celiac Patients Following a Gluten-Free Diet https://pmc.ncbi.nlm.nih.gov/articles/PMC8398893/ Nutritional Consequences of Celiac Disease and Gluten-Free Diet https://www.mdpi.com/2036-7422/15/4/61 Simplifying the B Complex: How Vitamins B6 and B9 Modulate One Carbon Metabolism in Cancer and Beyond https://pmc.ncbi.nlm.nih.gov/articles/PMC9609401/

      Thank you so much for the clarification! Yes to these questions: Have you consulted dietician?  Have you been checked for nutritional deficiencies?  Osteoporosis? Thyroid? Anemia?  Do you take any supplements, or vitamins? I’m within healthy range for nutritional tests, thyroid and am not anemic. I do have osteopenia. I don’t take any medications, and the dietician was actually a nutritionist (not sure if that is the same thing) recommended by my physician at the time to better understand gluten free eating.    I almost wish the gluten exposure had triggered something, so at least I’d know what’s going on. So confusing!    Many thanks!

      @JudyLou,  I have dermatitis herpetiformis, too!  And...big drum roll... Niacin improves dermatitis herpetiformis!   Niacin is very important to skin health and intestinal health.   You're correct.  dermatitis herpetiformis usually occurs on extensor muscles, but dermatitis herpetiformis is also pressure sensitive, so blisters can form where clothing puts pressure on the skin. Elastic waist bands, bulky seams on clothing, watch bands, hats.  Rolled up sleeves or my purse hanging on my arm would make me break out on the insides of my elbows.  I have had a blister on my finger where my pen rested as I write.  Foods high in Iodine can cause an outbreak and exacerbate dermatitis herpetiformis. You've been on the gluten free diet for a long time.  Our gluten free diet can be low in vitamins and minerals, especially if processed gluten free foods are consumed.  Those aren't fortified with vitamins like gluten containing products are.  Have you consulted dietician?  Have you been checked for nutritional deficiencies?  Osteoporosis? Thyroid? Anemia?  Do you take any supplements, medicine, or vitamins? Niacin deficiency is connected to anemia.  Anemia can cause false negatives on tTg IgA tests.  A person can be on that borderline where symptoms wax and wane for years, surviving, but not thriving.  We have a higher metabolic need for more nutrients when we're sick or emotionally stressed which can deplete the small amount of vitamins we can store in our bodies and symptoms reappear.   Exposure to gluten (and casein in those sensitive to it) can cause an increased immune response and inflammation for months afterwards. The immune cells that make tTg IgA antibodies which are triggered today are going to live for about two years. During that time, inflammation is heightened.  Those immune cells only replicate when triggered.  If those immune cells don't get triggered again for about two years, they die without leaving any descendents programmed to trigger on gluten and casein.  The immune system forgets gluten and casein need to be attacked.  The Celiac genes turn off.  This is remission.    Some people in remission report being able to consume gluten again without consequence.   However, another triggering event can turn the Celiac genes on again.   Celiac genes are turned on by a triggering event (physical or emotional stress).  There's some evidence that thiamine insufficiency contributes to the turning on of autoimmune genes.  There is an increased biological need for thiamine when we are physically or emotionally stressed.  Thiamine cannot be stored for more than twenty-one days and may be depleted in as little as three during physical and emotional stresses. Mitochondria without sufficient thiamine become damaged and don't function properly.  This gets relayed to the genes and autoimmune disease genes turn on.  Thiamine and other B vitamins, minerals, and other nutrients are needed to replace the dysfunctional mitochondria and repair the damage to the body.   I recommend getting checked for vitamin and mineral deficiencies.  More than just Vitamin D and B12.  A gluten challenge would definitely be a stressor capable of precipitating further vitamin deficiencies and health consequences.   Best wishes!
