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.

      Have Tru Joy Sweets Choco Chews been discontinued??

      Help! My 5 year old daughter just stopped eating dairy and gluten due to her EoE and Celiac. Her favorite candy in the world is tootsie rolls. I did some research, and it sounds like these are the only options for finding something similar, but I can't find them anywhere to actually purchase. Have they been discontinued?? Does anyone have another recommendation...

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

      I wonder how long it usually takes and if it is dose dependent as well... or if some ppl have a more pronounced reaction to gluten than others thanks again for all the great info

      Wow KK, thank you so much for all your attached info. I had a very quick scan but will read more in depth later. The one concerning corticosteroid use is very interesting. That would relate to secondary adrenal insufficiency I think , ie AI caused by steroids such as taken long term for eg asthma. I have primary autoimmune AI, my adrenals are atrophied...

      Awaiting dermatitis herpetiformis confirmation following biopsy

      Welcome to the forum, @suek54, I have Dermatitis Herpetiformis, too. I found taking Niacin B3 very helpful in clearing my skin from blisters as well as improving the itchies-without-rash (peripheral neuropathy). Niacin has been used since the 1950's to improve dermatitis herpetiformis. I try to balance my iodine intake (which will cause flairs...

      Awaiting dermatitis herpetiformis confirmation following biopsy

      Thank you all for your advice and the dermatitis herpetiformis article. The latter made me realise I had stopped taking my antihistamine, which I will restart today. The Dapsone has cleared the rash entirely but I still get quite a bit itching, absolutely nothing to see though. I know its notoriously hard to clear and its still relatively early days for me...

That would relate to secondary adrenal insufficiency I think , ie AI caused by steroids such as taken long term for eg asthma. I have primary autoimmune AI, my adrenals are atrophied, no chance if recovery there. But I am in touch with some secondaries, so something to bear in mind. .  Niacin B3 Very interesting too. Must have a good read about that.  Im sure lots of questions will arise as I progress with dermatitis herpetiformis. In the mean time, thanks for your help.

      Thank you all for your advice and the dermatitis herpetiformis article. The latter made me realise I had stopped taking my antihistamine, which I will restart today. The Dapsone has cleared the rash entirely but I still get quite a bit itching, absolutely nothing to see though. I know its notoriously hard to clear and its still relatively early days for me.  The iodine issue is very interesting. I do eat quite a bit of salt because I have Addison's disease and sodium retention is an issue. I also have autoimmune hypothyroidism, not sure how a low iodine diet would play into that? Because of my Addison's I am totally steroid dependent, I take steroids 4 x daily and cannot mount any defence against inflammation. I need to increase my meds for that. Now that I know what is wrong I can do just that if Im having a bad day. Life is very sweet, just so damn complicated sometimes! Hey ho, onwards. Thank you again for your advice.
