Hi Stacy,
I was told I had Hashimoto's when I went to John Hopkins. I had an ultrasound done and the tech went to get the doctor and he asked if anyone ever told me I had Hashimoto's.
Nothing changed with the dx for me. They just check my blood work about every 6 months. I think they only do that because I ask them to. I might ask for a TPO to be taken. I never heard of it before.
