Healthy thyroid function is essential to feeling energetic and vital. The thyroid is one of the key regulators of global energy production in the body, and thyroid dysfunction can be a source of fatigue or loss of vitality, with many patients not knowing that problems with their thyroid are causing their symptoms.

Hypothyroidism (reduced production of thyroid hormones by the thyroid) slows down metabolism and energy production, resulting in a range of symptoms including fatigue, weight changes, and mood disturbances.

In the UK about 1 in 50 people are diagnosed with hypothyroidism, but undiagnosed hypothyroidism may affect as many as 1 in 10 people. Additionally, the likelihood of developing hypothyroidism is higher for women and increases with age.

This test measures FT3 and FT4, the active thyroid hormones, and TSH, the pituitary hormone that regulates their production. Deviations in these levels can signify an underactive or overactive thyroid, which can impact the body's energy production and metabolic rate.

Markers Included In The Test

Free T3 (FT3): Free T3 (FT3) measures the level of triiodothyronine, a thyroid hormone that regulates metabolism in your body's cells. High FT3 levels can suggest an overactive thyroid (hyperthyroidism) leading to increased metabolism, while low levels can indicate an underactive thyroid (hypothyroidism) causing slowed metabolism, and symptoms such as fatigue, weight gain, and cold intolerance

Free T4 (FT4): Free T4 (FT4) is a test that measures the level of free thyroxine, a key hormone produced by the thyroid gland. High levels can indicate an overactive thyroid gland (hyperthyroidism), which can cause symptoms such as rapid heart rate, weight loss, and anxiety, while low levels may suggest an underactive thyroid (hypothyroidism), leading to fatigue, weight gain, and depression.

TSH: Thyroid-stimulating hormone (TSH) is a hormone produced by the pituitary gland to regulate the production of thyroid hormones, which control the body's metabolism. Abnormal TSH levels can indicate thyroid disorders. High levels may suggest an underactive thyroid (hypothyroidism) and low levels an overactive thyroid (hyperthyroidism). Both conditions can cause a wide range of symptoms including fatigue, weight changes, and mood disturbances.
