Thyroglobulin antibodies may be found in people who have a thyroid problem. These antibodies attack thyroglobulin proteins and can destroy the thyroid gland.
Thyroid peroxidase antibodies
The presence of these antibodies in your blood can suggest that the cause of thyroid disease is an autoimmune disorder, such as Hashimoto’s disease or Graves’ disease.
Free triiodothyronine, or Free T3, is used to assess thyroid function and can either be used to diagnose hyperthyroidism or monitor treatment of a person with a known thyroid disorder.
Free thyroxine (Free T4)
Free thyroxine helps to evaluate thyroid function and diagnose thyroid diseases, including hypo- and hyper-thyroidism. Free T4 is not affected by protein levels and is the active form of thyroxine.
Thyroid Stimulating Hormone (TSH)
The thyroid is a butterfly shaped gland found in the throat, wrapped around the windpipe just below the Adam’s apple. It produces thyroid hormones which influence essentially every organ, every tissue and every cell in the body. Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland and stimulates the thyroid gland to produce thyroid hormones thyroxine (T4) and triiodothyronine (T3). TSH that is too high or too low indicates that your thyroid gland is not functioning correctly.
