Thanks for the input, everyone!
Could you go to another doctor or get into a gastro in a timely manner? If not, you could try ordering a home Biocard test which tests for IgA and tTG IgA (in high levels). At least with the Biocard test you would know if your other IgA based tests are accurate.
I called this morning and scheduled an appointment with a gastro on July 29th - the earliest they could get me in. The practice was recommended to me by a friend who has celiac, so I'm hopeful that they will know what they're doing.
There are online labs where you can order complete celiac blood panels...and anything else you want. I'm in the US...don't know where you're at.
Thanks for the tip! I'm in the US, too, so I will definitely check that out. It might given me some extra info to share with the doc - and save time of him having to order it.
