About this test

How can a baseline thyroid function test help you?

This test will give you a basic view of key thyroid hormone levels, which can help check for hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). The test checks for two different biomarkers - the thyroid hormones TSH and FT4.

Combined with a GP report and advice, you can begin to understand your thyroid health and any associated symptoms.
