You will want your doctor to order other pituitary hormone tests though, because if there isn't enough TSH to stimulate the thyroid, there's a good chance there aren't enough other pituitary hormones to do their jobs either...
You'll want to get prolactin, FSH, Luteinizing hormone
, Growth Hormone
, ACTH, etc because these affect female and adrenal hormones, as well, and can be responsible for many symptoms, too.
Your ND should be willing to order these tests.
