Thyroid Stimulating Hormone (TSH)
TSH is a hormone produced by the pituitary gland and has the role of regulating the production of hormones by the thyroid gland. High TSH levels indicate hypothyroidism, and low TSH levels indicate hyperthyroidism.
Free Thyroxine (FT4)
Thyroxine is a hormone responsible for many vital functions including regulating metabolism, mood, and body temperature. High T4 levels indicate hyperthyroidism, and low T4 levels indicate hypothyroidism.
Free Triiodothyronine (FT3)
Triiodothyronine is a thyroid hormone that helps to regulate the body’s metabolic rate, heart and digestive functions amongst many other things. High FT3 levels indicate hyperthyroidism, and low FT3 levels indicate hypothyroidism.
Thyroglobulin Antibodies (TGAB)
A TGAB test is used to check the levels of antibodies the body has made against the compound thyroglobin, which is a protein produced by the thyroid gland to make the hormones T3 and T4. This test can help diagnose thyroid autoimmune conditions.
Thyroid Peroxidase Antibodies (TPO/TPEX)
A TPO test checks the levels of antibodies the body has made against the compound TPO, which is a protein produced by the thyroid gland to make the hormones T3 and T4. This test can help diagnose thyroid autoimmune conditions.
