Get a clearer picture of how your thyroid is functioning with a simple at-home blood test measuring three important thyroid markers: Thyroid Stimulating Hormone (TSH), Free Thyroxine (FT4) and Triiodothyronine (FT3). Suitable for both men and women, the Thyroid Function Blood Test can provide useful insight when investigating symptoms such as changes in energy, weight, mood, heart rate or temperature tolerance, with analysis carried out by a UKAS-accredited laboratory.
Your thyroid helps regulate metabolism and influences numerous processes throughout the body. When thyroid activity changes, the effects can appear in different ways, including changes in energy, body weight, mood, heart rate and how well you tolerate heat or cold. Because these symptoms can overlap with many other conditions, testing provides objective information about your thyroid hormone levels.
The Thyroid Function Blood Test measures TSH, FT4 and FT3. Looking at these markers together provides a more detailed view of thyroid activity and how your body is regulating thyroid hormones than considering symptoms alone. The test uses one finger-prick blood sample which can be collected conveniently at home.
Your sample is analysed by a UKAS-accredited laboratory and your results are provided digitally with explanations of your individual markers. The results can help identify readings outside the expected range and provide useful information to discuss with your GP or another healthcare professional, particularly where symptoms or existing thyroid treatment are involved.
