Which Tests Should I Order, (ttg) Or (aga)?

Hello, still researching on where to order tests. I found a website, direct labs, where I can order tests, and take the actual order to the lab near my home, in this case a labcorp, for testing. It sounds reasonable. They offer two different tests for celiac. One is the Tissue Transglutaminase Antibody Assay (tTG) and the other is the Anti-gliadin Antibody Assay (AGA). Can anyone help determine which test would be better? thanks in advance

tTG.

Have them do a complete panel, that would include both. If cost demands only one then do go with the Ttg. Do keep in mind though that the blood test does have false negatives, as does the biopsy so when you finish all your testing try the diet, strictly to see if it helps.

Total IgA

Ttg IgA

Ttg IgG

EMA (less accurate, but 100% specific for celiac)

Total blood count/chemistry

I'm newly diagnosed (Aug 8 to be exact!) but here is what the University of Chicago Celiac Center says about testing:

"Which is the correct Screening Test?

Anti-Tissue Transglutaminase (tTG-IgA) -- A screening test is commonly used when an individual is in a risk group for Celiac Disease, whether or not he/she has symptoms. This test is usually the one offered for Celiac screening events, as it is the most sensitive test available. "

it lists other tests as well, and gives an explanation

here is a link to their website

Hope that helps, I know it can be overwhelming with all the information out there.

      Unexpected gluten exposure risk from cultivated mushrooms

      Welcome to the celiac.com communiuty, @Matthias! Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure.

      Unexpected gluten exposure risk from cultivated mushrooms

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing...

      how much gluten do I need to eat before blood tests?

      I might suggest you consider buckwheat groats. https://www.amazon.com/Anthonys-Organic-Hulled-Buckwheat-Groats/dp/B0D15QDVW7/ref=sr_1_4_pp?crid=GOFG11A8ZUMU&dib=eyJ2IjoiMSJ9.bk-hCrXgLpHqKS8QJnfKJLKbKzm2BS9tIFv3P9HjJ5swL1-02C3V819UZ845_kAwnxTUM8Qa69hKl0DfHAucO827k_rh7ZclIOPtAA9KjvEEYtaeUV06FJQyCoi5dwcfXRt8dx3cJ6ctEn2VIPaaFd0nOye2TkASgSRtdtKgvXEEXknFVYURBjXen...

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that y...

Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products containing yeast because of the fact that they are sometimes cultured on gluten-containing substrate.

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing from a visible layer of shredded cereals that had not been removed. After a quick web research I learned that these mushrooms are commonly cultivated on a cereal-based medium like wheat bran. I hope that info his helpful to someone.

Incidentally, I don't like quinoa either. Reminds me and smells to me like wet grass seed. When its not washed before cooking it makes me ill because of saponins in the seed coat. Yes, it can be difficult to get much dietary calcium without dairy. But in many cases, it's not the amount of calcium in the diet that is the problem but the poor uptake of it. And too much calcium supplementation can interfere with the absorption of vitamins and minerals in general because it raises gut pH.

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.
