I just discovered this at home gluten testing kit. Wondering if anyone has tried it or has any opinons about this. Seems expensive to me, but if I was very sensitive I would consider taking them along to a restaurant or when invited over for dinner at someone's house. I didn't read all the information, but it says results in 10 min.

With the ELISA test kits that I've used in the past, the product samples had be very finely ground, and samples and reagents used in the tests had to be carefully measured or weighed, or the results would be skewed. Also, most steps in the extraction process of an ELISA test have to be carefully timed, or that will skew the results, also. I'm guessing that for accurate results, any food samples would have to be below about 15% moisture, also, which is typical of grains, flours, etc, but cooked foods have a much higher moisture content.
Compared with the test kits that I've used, their price is reasonable, but I find it hard to believe that one can expect accurate results outside of a laboratory setting. IOW, this might work at home, but I would be surprised if it were practical in a restaurant, or any other situation where the food is cooked, and ready to eat, and the food is getting colder and colder while one is fiddling with the steps required for the test procedure. The timed procedure itself might require 10 minutes or less, but the total elapsed time will more than likely be 15 minutes or longer, based on my experience.
With a test threshold claimed to be 10 ppm, my guess is that a heck of a lot of commercially processed products, would test positive, (if the test is accurate, and the tests were carefully done).
I could be all wet, though.
It sounds like a good idea, but I wonder how many people will buy some of these kits, and never use them, or maybe try one of them, and realize that it's more trouble than they care to fiddle with.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.
It does say you can test beverages. But you are right, it really would not be feasible outside the home. 10 minutes is the time that the strip is to sit in the solution. Add to that the mixing and preparing time and the drying time of the strip and you have more like 25 minutes.
I read that the European standard for something to be called gluten free is 20 ppm. I wonder how they determined that level.

Standards in Europe have been set by the Codex Alimentarius Commission, since 1979. The basic standard was 200 ppm for years, until it was revised in 2008 to 20 ppm. The revision was apparently based on the flimsy evidence reported by the research project supervised by Dr. Fasano, that I described in post number 8 in the thread at this link:

IOW, apparently their regulatory agencies are no smarter than ours, (the FDA).
