I know I commented on IG but I also want to let our tribe know that:
Even if your full bloodwork is dismissed - get an ultrasound. Endocrinologist wrote me off. All scans of my thyroid confirm hashimotos when my blood work doesn't. If you find yourself with the same struggle as Kim and they don't care about the full thyroid panel (my doctors did not care about high rt3 or bad ratios, and I don't have enough detectable antibodies in my bloodwork), a physical scan of your thyroid can be a defense.
