The thyroid affects practically all cells in the body, and has a key role in metabolism, growth, body temperature, sleep and fertility. When the thyroid is not functioning correctly, symptoms can be vague and a blood test can be an easy way of identifying a problem.

This test measures your levels of the three thyroid hormones and, for this advanced test, we measure your Anti-TPO Antibody Status and Levels.

What’s included in the analysis?

The thyroid is a gland located in the neck that produces hormones that regulates the body's metabolism, how we use and store energy. This test is used to diagnose and control hypothyroidism and hyperthyroidism, which can be the cause of weight gain, tiredness and fatigue, feeling cold and mental health problems. 

Free Thyroxine (FT4): T4 is the most abundant thyroid hormone in the blood. However, only about 1% of T4 in the blood is freely available for use by cells, the rest is bound to a protein. A FT4 test measures the amount of T4 that is biologically active in the blood and can exert an effect on bodily functions.

Triiodothyronine (FT3): T3 is thought to be responsible for most, if not all of the effects of thyroid hormones. About 20% of T3 in the blood is secreted by the thyroid gland, with the remainder being produced by the conversion of T4 in cells around the body. Like T4, most of the T3 molecules in the blood are bound to a protein and only a very small fraction is freely available and biologically active.

Thyroid-Stimulating Hormone (TSH) is produced by the pituitary gland and is responsible for regulation of the secretion of T3 and T4 from the thyroid gland.

Only available in the Advanced Thyroid Function Test.

Anti-TPO is a type of autoantibody. Autoantibodies are produced by the immune system, and are similar to antibodies which are produced against viruses and bacteria, but instead of outside invaders, autoantibodies target the body itself. In this instance anti-TPO targets thyroid peroxidase (TPO) - an enzyme found in the thyroid gland, needed for the production of thyroid hormones.
