The TSH Test (Thyroid-Stimulating Hormone Test) measures the level of thyroid hormone stimulation in your blood, helping evaluate how well your thyroid gland is functioning. It plays a key role in diagnosing thyroid disorders such as hypothyroidism or hyperthyroidism and helps monitor treatment effectiveness. Maintaining balanced TSH levels is essential for energy, metabolism, and overall hormonal health.
A FT4 test measures the blood level of the hormone FT4, also known as thyroxine, which is produced by the thyroid gland and helps control metabolism and growth. The T4 test is performed as part of an evaluation of thyroid function.
