Thyroid Blood Test
Thyroid Blood Test
The Welzo Thyroid Blood Test is a targeted diagnostic panel designed to assess your thyroid gland’s function and its impact on energy, metabolism, and overall wellbeing. Thyroid dysfunction is common, particularly among women, and often goes undiagnosed due to its subtle or overlapping symptoms. Whether you're experiencing unexplained fatigue, weight changes, mood disturbances, or irregular periods, this test can help uncover the root cause.
Backed by research from organisations such as the British Thyroid Foundation and University of Edinburgh’s Centre for Cardiovascular Science, this panel evaluates the three most clinically relevant markers of thyroid health: TSH, FT4, and FT3. This offers a comprehensive view of your thyroid hormone balance and how it may be influencing your metabolism and daily functioning.
What Does This Test For?
This test examines the core hormones involved in thyroid function to determine whether your thyroid is underactive (hypothyroidism), overactive (hyperthyroidism), or functioning normally. It measures thyroid-stimulating hormone (TSH), which controls thyroid activity, and the two active hormones produced by the thyroid gland itself—free thyroxine (FT4) and free triiodothyronine (FT3). Together, these results offer a clear picture of how well your thyroid is working and whether there are any imbalances affecting your energy levels, weight regulation, mood, or temperature sensitivity. This test is often used for screening, diagnosis, or monitoring of known thyroid conditions.
