I doubt very much that it contains any gluten. It works by producing an artificial blood clot, mixing 2 or more proteins found in the natural blood clotting cascade. These are refined from human blood donations. It comes in 2 vials that are mixed immediately before use and clot quickly.

This literally happened to me today I had gluten after not eating it for over 6 months doing the elimination diet has I'm trying to get help with a diagnosis I ate gluten a few days ago and then stopped  because I went for my blood test today unfortunately it's not enough has I've now learned from some helpful people on this forum it has to be a lot longer before a test but my food today was really salty I just thout it was me because I'd deviated off my diet but I definitely tasted my  food  salty so that's a very intriguing investigation for me now thankyou for the post 

Fantastic info 👍

Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy: and this recent study recommends 4-6 slices of wheat bread per day:    

Thanks for posting that Scott I will arm myself too I had a blood test today and a fecal test for calprotein I'm not expecting any positive results I've been gluten free for over 6 months but I will be back has Arnold says with that information 👍
