No, but your doctor could run a Thyroid Panel and test T3-Free, T4-Free, TPO Antibodies (sounds like you may have Hashimoto’s disease with the hives), and TSH Levels. I suffer from Hashimoto’s and had hives until I stopped eating gluten, dairy and soy. Gone, poof! It’s like magic, but people don’t want to hear that they should stop eating these things, but they are the very things that make our bodies go bonkers! Give it a go, it does work!
