This Thyroid Function Test Measures:

Thyroxine (T4) is the most prevalent thyroid hormone produced by the thyroid gland.

It is responsible for many vital roles in the body including, metabolism, heart and muscle function, brain development and bone maintenance.

Measurement of Free Thyroxine (FT4) is used to assess thyroid health.


TSH stands for thyroid stimulating hormone. It's responsible for regulating your thyroid gland.

TSH is made in a gland in the brain called the pituitary. When thyroid levels in your body are low, the pituitary gland makes more TSH. When thyroid levels are high, the pituitary gland makes less TSH.

The thyroid is a small, butterfly-shaped gland located in your neck. The thyroid produces hormones which act on other parts of the body to influence and regulate their metabolism (energy usage).

When your body releases too much thyroid hormone (Hyperthyroidism - an overactive thyroid) or too little (Hypothyroidism - an underactive thyroid) then some cells and tissues in your body work faster or slower than they should do.

This test panel tests for two key Thyroid hormones; Free thyroxine which directly increases metabolism, and TSH which is released by the pituitary gland to regulate thyroxine production.
