It is possible to have thyroid problems despite having normal thyroid function tests. If blood test results show that the thyroid is functioning within normal ranges, patients with symptoms should talk to their doctors to rule out other problems of the thyroid including, autoimmune disorders, thyroid nodules, or thyroid cancer. Further work-up will likely involve checking for antibodies in the blood, ultrasound evaluation of the thyroid, and biopsy of any suspicious thyroid nodules.

Thyroid gland: background, thyroid tests
Thyroid disease can be detected by a careful medical history and then confirmed with a blood test. Sometimes a woman may have troublesome symptoms but her thyroid blood tests are only mildly abnormal. These individuals may have subclinical hypothyroidism. Additional specialized blood tests can show that thyroid gland function has been disturbed.
Rarely, thyroid disease can be present with normal laboratory results. This requires specialized blood work or an ultrasound of the thyroid to check for nodules that may disrupt the metabolism.
