Testing Iga Igg Etc

My doctor wrote 3 tests and he asked me if I wanted to do all of them as they are expensive. I don't think he sees many patients asking for these tests but he was very cooperative when I described my sympoms.

-IgA Antiendomysial

-IgA Antigliadin

and IgG antigliadin

are the last two different?

Also, can someone tell if I have to pay for lactose and fructose intolerances and other food allergy tests? Should I keep consuming some milk before being checked for lactose intolerance. I haven't had milk for months but I was using creme in my caffeinated drinks and stopped for the last 3 weeks.

Thank you.

Yes, the last two are different. You also want the total IgA test done.

My understanding of the lactose/fructose intolerence tests is that patient is given a drink containing the ingredient in question (such as a kool-aid type juice drink for the fructose test) then made to breath into a device to measure the gasses released.

It sounds expensive. Do you have insurance? If so, check with them first to know what your portion of the bill will be. If not, check with the practioner first to know exactly what is to be charged. Perhaps you could work out a payment plan?

So what's the total IgA test my doctor is sending me for the 3 above tests. What are the necessary tests to check celiac D?

You also need the IgG tTG and IgA tTG. Along with total IgA, those are the most important tests for diagnosing celiac disease.

The tTG IgG test is generally recommended to be run only if the patient is IgA deficient.

Info on testing: Open Original Shared Link

"Of the commercially available serologic tests that aid in the diagnosis of celiac disease, no one test is ideal. Using multiple serologies increases the diagnostic yield. Therefore, in the United States, screening in patients with possible celiac disease should consist of a panel of the following serologic tests:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level."

      Flapjack is as British as Fish & Chips!  Oats, butter, sugar, golden syrup... yum.  I have just returned from Fowey in Cornwall having discovered they have a branch of this amazing, award winning flapjack shop in the town.  I would thoroughly recommend that all coeliacs visiting Cornwall and Devon, who can tolerate pure oats, to drop in and buy one buy one (or several).  The oats used in Flapjackery's recipes are certified gluten free.  How wonderful for us coeliacs to be able to go into a shop and buy absolutely EVERYTHING on sale!  They come in so many interesting flavours including blackberry, cream tea, clotted cream, millionaires, salted caramel, tropical fruit, Eton Mess...  Also available by post. https://www.flapjackery.co.uk/

      As mentioned earlier in this thread, one of our sponsors here, Tierra Farm, sells certified gluten-free nuts and has a free shipping deal going now: https://www.tierrafarm.com/discount/gfships Coupon code: GFships

      I'm sure you can find other gluten-free versions here. You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
