I would pressure the lab to do the IgA control test for free so that you won't write a poor review about their testing services. You could get this done at any time, whether or not you are gluten-free, however, the celiac disease Tissue Transglutaminase tTG-IgA test must be done after you've been eating lots of gluten for around 6 weeks. This way you could... -

celiac, chocolate and alcohol
Given your strong reactions it would be wise not to eat things offered to you without reading the ingredient labels. It's possible there was indeed gluten or some allergen in the chocolates--barley malt is a common ingredient in some chocolates. -

Yes, an IgG panel is the logical next step. However, you would still need to be consuming normal amounts of gluten to ensure valid IgG testing. Since it has only been a week that you have been off gluten, there is still likely time to restore antibodies to detectable levels before the blood draw. IgG antibody tests are not quite as specific for celiac disease... -

Thanks @trents. I have exchanged some messages with the clinic today, and they are saying that the reason there is no result for the total IgA levels is because I don't have any. Apparently a negative result means that it does not appear as a line on the results at all. I am not sure I buy this, but it is what they are telling me. I am leaning more towards... -

Newbie with Celiac / NCGS symptoms
IGA deficiency is a lot more common than we used to think but I can't give you a number. Doctors used to believe it only happened in children but we know better now. Every doctor should order, at the very minimum, total IGA and tTG-IGA. It may be true that you don't have to worry as much about cross contamination if you have NCGS but that is not a given. ...

You could get this done at any time, whether or not you are gluten-free, however, the celiac disease Tissue Transglutaminase tTG-IgA test must be done after you've been eating lots of gluten for around 6 weeks. This way you could salvage the results of your tTG-IgA test, as long as you were eating lots of gluten beforehand. -

Yes, an IgG panel is the logical next step. However, you would still need to be consuming normal amounts of gluten to ensure valid IgG testing. Since it has only been a week that you have been off gluten, there is still likely time to restore antibodies to detectable levels before the blood draw. IgG antibody tests are not quite as specific for celiac disease as are the IGA tests but they are certainly valuable in the case of IGA deficiency. They also seem to have a little more "staying power" in the sense of detecting celiac disease in the case of those who may have already started a gluten-free diet as long as they haven't been on it for an extended period of time. But don't rely on that. Get back on gluten if you can possibly endure it if you intend to go forward with IgG testing. This might be helpful:

Thanks @trents. I have exchanged some messages with the clinic today, and they are saying that the reason there is no result for the total IgA levels is because I don't have any. Apparently a negative result means that it does not appear as a line on the results at all. I am not sure I buy this, but it is what they are telling me. I am leaning more towards the theory that they didn't test it in the first place. But, working on the basis that the test result was zero, I asked what the next steps would be, given that I apparently have no IgA antibodies. They have asked if I now want to have a tTG-IgG and a DGP-IgG test. Is this really the next step if I have no total IgA?

By the way, welcome to the forum, @SEQ!
