This comprehensive test checks the full function of your thyroid gland. It includes central thyroid gland regulation and activity, thyroid production and secretion, peripheral thyroid conversion, and thyroid autoimmunity.

Over 4% of people currently have low thyroid function and do not know about it. It is a notoriously difficult condition to diagnose by symptoms or medical examination.

It is a blood test that gives you a definitive answer and can potentially avoid months, and often years, of unexplained tiredness, weight gain, dry hair, constipation, menstrual problems, depression, anxiety, and more. If your thyroid is overactive there is a whole other set of problems that need treating.

At least 1 in every 8 women will have problems with their thyroid function during their lifetime.

Thyroid stimulating hormone, free T4 and free T3 check the function of your thyroid and thyroglobulin antibodies and thyroid peroxidase antibodies check whether you have an autoimmune condition (known as Hashimoto's thyroiditis) which can be causing your thyroid not to function as it should.

This test is essential for anyone who wants to know more about their thyroid function.

Biomarker(s) Measured: Free T4 (thyroxine), Thyroid Peroxidase Antibodies, Antithyroglobulin Antibodies, Thyroid Stimulating Hormone, Free T3 (triiodothyronine)
