My sister has just sent me this link, and wanted to share:
https://celiachometest.com/Home test kits for celiac disease - a blood test, where you prick your finger and wait for a blood result. Just wanted to put the info out there as I know that often doctors don't want to test as it is expensive. Much less invasive and upsetting as the bowel biospies my mother had to go through 15-20 years ago to have her celiac disease diagnosed.
That's all, just sharing!
