Pre Blood Test Questions

I just ordered a Celiac panel blood test.

 

There are instructions on the webpage for the test that state the following.

 

 

Reminder: Be sure to fast for 10-12 hours prior to blood draw. You may drink water or black coffee during your fast. In additon, it is recommended that you refrain from vigorous excercise 24-48 hours prior to your blood draw. If you currently take medications, please stay on your current schedule.

 

 

Everywhere I have read says that fasting before a Celiac blood test is not necessary.  I think the instructions above are general for all blood tests.

 

Someone mentioned in another thread that it is good to eat the "equivalent of four slices of bread a day for 12 weeks". Someone mentioned 2 slices.  How much gluten is in 2 or 4 slices of bread?  What exactly would be equivalent?  I do eat pasta 2x a week.

 

If I would to eat a lot of flour products a few days before the test, would a more accurate diagnosis be likely?

 

Everyday I eat a bread called Ezeloe; 4:9.  It is a sprouted grain bread.  The website says the following about the gluten content.

 

Q: Are Food for Life sprouted grain foods "gluten free"?

A: No. Food for Life breads contain naturally occurring gluten. However, our unique sprouting process activates enzymes, which naturally metabolize starch, carbohydrates and gluten protein. This may explain why so many gluten sensitive people may tolerate sprouted grains.

 

 

Since the gluten is metabolized, does that mean it would affect the blood test diagnosis whether I have Celiac?  Should I eat regular bread instead?

 

I can surmise the answers to these questions.  I would appreciate any responses, but would like to know if the answers are surmises or based on fact.

i had to fast before mine, but they were also doing other tests and drawing all the blood at the same time.  no idea if you should eat more gluten or not since you haven't gone gluten free already.  i'm thinking the extra bread was only if you had been gluten free and re-introducing it for testing purposes.  i went gluten free before my celiac testing and my doctor advised (since i was feeling a million times better and that i was so malnourished and underweight) that i did not return to eating gluten or even risk a gluten challenge.

Excellent point about re-introducting for testing purposes.  I imagine a regular diet would have enough gluten.  Although, I might switch breads to a flour based.

      Working in a kitchen with gluten?

      By PixieSticks · Posted

      Hi yes! I was diagnosed 10 years ago through a biopsy. I’ve been gluten free ever since but no one I’m around is gluten free. I sometimes wore a surgical mask in the kitchen. but I believe particles were still getting through. I’ll definitely look into n95 instead. thanks for the reply.

      Ya I used to react to iodine, but it doesn't bother me anymore after strict adherence to a gluten-free diet for many years now. I am happy to report that for the first time ever in my life, a probiotic formula is not making me break out, but actually seems to be helping. The strains in this formula have been specifically tested to help with skin issues. It is gluten and dairy free also.

      Feeling ill

      @Whyz, I take a combination of Thiamin (Benfotiamin), B12 Cobalamine and Pyridoxine B6 for my pain and headaches.  Really works well without hurting the digestive tract.  Riboflavin B2 also helps with migraines.  Most newly diagnosed people have vitamin and mineral deficiencies.  Check with your doctor and nutritionist.   If you follow the updated gluten challenge guidelines, you can wait until two weeks (minimum) before your appointment, then eat lots of gluten, like six slices of gluten containing bread or "name your poison".   Here's the Updated Gluten Challenge Guidelines: Recommended intake of gluten should be increased to 10 grams of gluten per day for at least two weeks. Or longer. While three grams of gluten will begin the immune response, ten grams of gluten is needed to get antibody levels up to where they can be measured in antibody tests and changes can be seen in the small intestine.   Keep in mind that there are different amounts of gluten in different kinds of bread and gluten containing foods.  Pizza crust and breads that are thick and chewy contain more gluten than things like cake and cookies.   References: https://www.beyondceliac.org/celiac-disease/the-gluten-challenge/ And... Evaluating Responses to Gluten Challenge: A Randomized, Double-Blind, 2-Dose Gluten Challenge Trial https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7878429/?report=reader  "In our study, limited changes in Vh:celiac disease (villi height vs crypt depth - aka damage to the small intestine)  following 14-day challenge with 3 g of gluten were observed, in accordance with Sarna et al.  While the 3 g dose was sufficient to initiate an immune response, as detected by several biomarkers such as IL-2, the 10 g dose was required for enteropathy within the study time frame. Based on our data, we would suggest that gluten challenge should be conducted over longer durations and/or using doses of gluten of ≥ 3 g/day to ensure sufficient histological change can be induced." Keep us posted on your progress!

      Advantages vs. Disadvantages of having an official Celiac diagnosis

      By Scott Adams · Posted

      I don't believe that existing life insurance policies require such notifications--health checks are typically done before such policies are obtained. I believe it would primarily affect any new policy you get, and perhaps any policy renewal.

      You could go gluten-free now, and then start eating lots of gluten for at least 2 weeks before your endoscopy--just be sure to tell your doctor about this beforehand. If your symptoms go away on a gluten-free diet, it is further evidence of celiac disease and/or non-celiac gluten sensitivity.  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
