Thyroid Test
Thyroid tests are blood tests used to evaluate how well your thyroid gland is functioning. The thyroid gland, located in your neck, produces hormones that regulate many vital body functions, including metabolism, growth, and energy levels.
Common Thyroid Tests
• Thyroid-stimulating hormone (TSH): This test measures the amount of TSH produced by your pituitary gland. TSH stimulates the thyroid gland to produce thyroid hormones.
• Thyroxine (T4): This test measures the level of T4, one of the main thyroid hormones.
• Triiodothyronine (T3): This test measures the level of T3, another main thyroid hormone.
• Free T4 and Free T3: These tests measure the amount of T4 and T3 that is not bound to proteins in your blood, which is the form that can enter your cells and affect your body.
• Thyroid antibodies: These tests measure the levels of antibodies that can attack the thyroid gland, causing autoimmune thyroid diseases such as Hashimoto's disease and Graves' disease.
