HI and thank you for your response.
This was a few years ago that I took the test and it was a blood test. I'm not sure, but I think I took one both in the am and in the pm
Ironically, I recall having a bladder type problem once and avoiding foods that were acidic and losing weight unexpectedly.
I thought that all I had to do to avoid the great majority of gluten in foods was to avoid bread and flour.
It seems there is much more to it.
I DO eat at restaurants regularly and once in a while have a small piece of a cookie, etc. However, I do keep any intake of a bread/cake product very, very small. Why is there more gluten in restaurant food?
