Testing Iga Igg Etc

[Nadia2009]

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?

Yes, I have insurance. Thanks for the tip.

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."
