How can an advanced thyroid function test help you?

This test will give you a detailed look at your thyroid hormone levels and thyroid antibodies, which can cause autoimmune thyroid diseases. Issues with your thyroid can affect your weight, energy, mood, heart, and bone health.

This test checks for 6 different biomarkers - four thyroid hormones (TSH, FT3, T4 and FT4), and two thyroid antibodies (TgAB and TPOAb).

Combined with a GP report and advice, we help you understand your thyroid health and any associated symptoms.
