Welcome to the forum, @Janet McAlpin! Using the gluten-free label doesn't mean there is 0 gluten in a product. It means there is <20ppm of gluten according to FDA standards. So, it is not surprising that there is some gluten in this product. What is the sensitivity of the ELISA test you are using? And the NIMA device has a reputation for giving erratic results.

Hello all, I have been using Elisa tests to slowly go through many ingredients in my kitchen to confirm they are gluten-free. Today, after eating Bob's Red Mill TVP, I didn't feel great. I decided to test it and the result found gluten. I am going to test all the Bob's Red Mill products I use regularly with the Elisa tests. I have found them to be quite accurate. I also use NIMA and can't wait for them to be back! I'll keep you posted! Janet

Thank you for your reply Knitty Kitty (from a fellow knitter) My TSH and T4 is within normal range, and has been checked along with the rest of my bloodwork consistently over the past many years. I am very aware of Hashimoto's since my mom has it  (she does not have celiac disease, her other autoimmune disease is diabetes (which I am monitored for but don't have - I "only" have allergies).  And yes - I eat iodized salt to protect my thyroid. Good suggestions though and thank you for the links. 

Progesterone stimulates the thyroid.  The thyroid stimulates the immune system which increases production of IgG antibodies.   Progesterone Upregulates Gene Expression in Normal Human Thyroid Follicular Cells https://pmc.ncbi.nlm.nih.gov/articles/PMC4454767/ Celiac Disease and Autoimmune Thyroid Disease: The Two Peas in a Pod https://pmc.ncbi.nlm.nih.gov/articles/PMC9312543/  

@Mettedkny, Have you had your thyroid checked lately?  People with thyroid problems like Hashimoto's thyroiditis produce tTg IgG antibodies whether exposed to gluten or not.  Hashimoto's is another autoimmune disease frequently found with Celiac disease.  Do you eat iodized salt or sea salt?   P.
