Trans-glutaminase Antibodies Test

[lucky28]

Does anyone have an opinion or have experience with this test. I ordered one from "great plains lab" and was not sure if this was the best type of test to use to confirm or not. I have no insurance and I am a full time student on a tight budget but I really want to find out if I do have celiac or not. I think I do but then again maybe it is something else. I am looking for the least expensive yet most reliable test I can find. If anyone has advise --Thank You

ps> I was gluten-free for about a month and had my first normal bm in about 20yrs. but I began a gluten challenge 2 days ago and no D -- yet but massive bloating , could be gluten or the cheese on my sandwich at work today- I know for sure I'm lactose int. but a slice of cheese is usually ok

If you were gluten free for a month then that can interfere with the accuracy of tests. The tTG test is one of the most specific tests for celiac so yes that is a good test to get done. I had this test done by prometheus labs and it came back high.

It is also a good idea to have the IgA test along with the TTG test in case you are IgA deficient with celiac disease. If you are IgA deficient and have celiac disease the test can sometimes come back as a false negative.

Thanks karen and kaiti for the replies. I think I'm not going to be able to stay on the gluten challenge until the 23rd (my appt). I just don't want to go through the bloating, big D, crampy, tired and foggy way I feel . I spent the last 10++ years feeling like cr**. and it seems worse now since I had been gluten-free for over a month. Plus I don't have insurance and I start school in 3 weeks, full time in addition to a full time job. I think I would rather spend the $$ on gluten-free foods than on the tests that will tell me I need to buy gluten-free.
