I knew from my labwork, that's really the only way to know.

I joined the Paloma Health community. You can order test kits and connect with thyroid doctors. I recommend checking out their site and seeing if their pricing works for you.

I went to a place called medlink. It uses a sliding scale for people that doesn't have insurance. They ran some blood test and all of my numbers came back extremely high and they confirmed I had hashimotos.

I knew i had before the doctor found out- I actually went to my doctor with my problem but i never mentioned hashimoto I just said I think there is something wrong with my thyroid- they kept testing and everything came back normal, until a third doctor knew what to ask me and she did the right test! U have to ask them to test for antibodies attacking your thyroid- because ur hormones could be normal but it only means that your thyroid is overworking and it goes up and down all the time!! I just knew because I had pretty much all the symptoms of hashimoto!!

I’m in the process of bloodwork and appts dicussing this for me. All signs so far point to yes but will find out at my next appt.

I knew when I started having hives and blood tests confirmed it

Everlywell.com offers a membership for $25/month. You can order the thyroid kit and test yourself.

I second that when you have your thyroid levels run, make sure to check TPO (thyroid peroxidase) Antibodies. My thyroid levels are often within a standard range but my TPO Ab are almost always high with Hashimoto's.
