Absolutely do not consume wheat grass if you have Celiac Disease! Same thing with barley grass. And rye grass if there is such a thing.
When I was diagnosed with Celiac Disease by a gastroenterologist who specializes in Celiac research, the doctor made it cristal clear that my body cannot tolerate even trace amounts of wheat, barley, rye, or their derivatives.
There is NO WAY for wheat grass manufacturers to guarantee that no seeds (also referred to as grain or berries) have formed in an entire field of grass being harvested. Additionally, manufacturing facilities where wheat is processed are likely to contaminate non-wheat products due to shared equipment and wheat dust throughout the air in the factory. The USDA allows products to be labeled gluten free even if the product contains up to 20 parts per million of gluten!
It is best to buy products labeled "manufactured in a dedicated gluten free facility". If you decide to trust products claiming they test for gluten in their products, be sure to verify
that it's been tested for gluten cross-contamination with a specific type of test: the R5 ELISA test. Other forms of testing may not produce accurate results, since they may underestimate the amount of gluten in the product. Additionally, it is common practice for ingredient manufacturers only test random batches, not every batch of product.
I have Celiac Disease and recently got a sudden itchy rash on both thighs, seemingly out of the blue. The only new thing in my diet is my "super greens " I started adding to my morning smoothies. The rash lasted for a week, slowly getting itchier, more red/irritated, and spreading up my leg. I stopped using the powdered greens (containing wheat grass & barley grass) and the rash has greatly improved.
I'm warning you so you do not made the same mistake I did, as I even contacted the manufacturer who claimed the ingredients cannot have gluten and that they test for gluten just to be sure. I will not consume products derived from any part of wheat plants, rye plants, or barley plants in the future, no matter what!
