Need To Be On Gluten To Have Blood Testing Done?


RatPack

Recommended Posts

My 19-month-old son has had frequent, loose stools and scaly rashes since I can remember. I always suspected some sort of food intolerance but wasn't incentivized to do anything until his most recent check-up showed that he went down and off his growth chart (he was under the 5% for weight and not much better for height). I decided on my own to put him on an elimination diet at the beginning of the year just to see what happened. His stools became solid and less frequent (2 a day rather than 5 a day). He also gained two pounds in 1

Hi, I am new to the forum,(thus the empty reply) but I work for Celiac.com & we have an autoreply that I thought would help you. For your review:

Celiac.com cannot offer any medical or dietary advice, other than to recommend that people with celiac disease should maintain a 100% gluten-free diet for life, and anyone who believes that their symptoms could be caused by celiac disease or gluten intolerance should be screened for it (we recommend that everyone be screened for celiac disease because its symptoms can range from none to almost any unexplained health problem--not to mention the fact that around 1 in 100 people actually have it and most never get diagnosed and treated).

Screening for celiac disease is a simple blood panel that includes these tests (please note that you should still be consuming gluten in order for the antibodies to be present):

Anti-endomysial antibody IgA (EMA)

Anti-reticulin antibody (ARA)

Anti-gliadin antibody IgA (AGA)f

Anti-Gliadin IgG (AGA)F

Anti-Tissue Transglutaminase (tTG) Antibodies

I hope this helps! Best wishes to you & your little guy. :)

My questions for anyone out there with some knowledge of testing for celiac disease are:

1. Does my son need to go back on gluten to take the blood test? Please say no!

2. Should I have the blood test given prior to the visit with the GI?

3. Should I have him tested for the two celiac-related genes? My husband

Question for y'all.

I had the Enterolab Intolerance Test with a score of 33. My Dr., says she would like to have the celiac panel done to confirm Celiac Disease. I'm confused after reading all the posts on where to get the best test...I'm not sure how to determine that.

Quest Labs blood tests include only 3 of the 5 that you recommend. TTG, IGA and one of the Anti-Gliadin antibodies...(not sure which one). The cost is $273. I live in Kansas City and there's a Quest lab nearby.

LifeExtension Lab offers this for $99:

Deamidated gliadin IgA; tissue transglutaminase IgA; serum IgA quantitation.

Is there a better lab to get a broader spectrum panel or better pricing or ???

I'm new to all of this so not sure where to go to get the best test without breaking the bank. (limited health insurance coverage), yet still get the best panel.

Also, I have gluten-free for one month...how long do I need to be eating gluten for blood testing?

THANKS for your help.

~You are testing for the damaging reaction for gluten in the body.

~Only have the blood test prior to the ped gastro appointment if the two doctors are on the same page and want the same panel drawn. The results should then be sent to both docs. The labs are somewhat determined by your health insurance.

~Genetic testing is still "new". Not as readily covered by insurance. Positive results can get a "probable" Celiac diagnoses, but not the "gold standard". Not every Celiac gene has been identified. The test can be said to be 98% accurate. Not good enough if you fall into the 2% the lab knows the are going to miss.

~Damage resulting from Celiac or DH destroys the villi which interfers with all nutrient absorbtion and digestion.

~There are so many differering opinions on how much gluten to be eating and how long before the test. Most say the amount should be at least a bread slice a day, and I don't know the best length of time to tell you. Ask your doctor, some say 2 weeks to 2 months. (it is said that one micron, about the size of a crumb, can cause a symptomatic reaction) Gluten challenges can be dangerous. My daughter was hospitalized for dehydration.

Good Luck. I hope you find you answers quickly and your healing is even quicker.

And, there are newer/better tests in place of the AGA test: anti DGP

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

      Been off this forum for years. Is it that important that you get an official diagnosis of something? It appears like you had a trigger (wheat, gluten, whatever) and removing it has resolved your symptom. I can't speak for you, but I had known what my trigger was (gluten) years before my diagnosis I would just stay gluten-free and get on with my symptom free condition. I was diagnosed over 20 years ago and have been symptom free only excluding wheat, rye and barley. I tolerate all naturally gluten free whole foods including things like beans which actually helps to form the stools.

      No coincidence. Recent revisions to gluten challenge guidelines call for the daily consumption of at least 10g of gluten (about the amount in 4-6 slices of wheat bread) for a minimum of 3 weeks. If possible, I would extend that two weeks to ensure valid testing.

      Thank you both for the replies. I decided to bring back gluten so I can do the blood test. Today is Day #2 of the Challenge. Yesterday I had about 3 slices of whole wheat bread and I woke up with urgent diarrhea this morning. It was orange, sandy and had the distinctive smell that I did not have when I was briefly gluten free. I don't know if it's a coincidence, but the brain fog is back and I feel very tired.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!
