“If your doctor told you that your thyroid was normal based on a TSH test, but you feel symptomatic you may want to push for more testing (or find a new doctor). TSH is a pituitary test. Here is a list of labs (along with what they do) that will test your thyroid function and not your pituitary’s reaction to your thyroid.

Total T4-This is your storage hormone

Free T4-This is how much of this hormone is free for the body to use and convert to T3

Total T3-This is the active hormone

Free T3-The amount of active hormone that is available to your body to use.

TPO and TgAb-These are thyroid antibodies tests. This test helps you determine if you have an autoimmune thyroid problem.
