Tests
A thyroglobulin test measures the amount of a protein called thyroglobulin (Tg) in a sample of your blood. Your thyroid (a small, butterfly-shaped gland in your neck) makes thyroglobulin along with many other important hormones . Together, these hormones control bodily activities such as your heart rate and how fast you burn calories from food.
Indicators
Thyroglobulin (2768 aa, ~305 kDa) is encoded by the human TG gene. This protein is involved in thyroid hormone synthesis.
Tests
A thyroid antibody test measures the level of thyroid antibodies in a sample of your blood to check for an autoimmune thyroid disease . Your thyroid is a small, butterfly-shaped gland in your neck.

Tests
The determination of the amount of thyroid stimulating immunoglobulin autoantibody present in a sample.
Indicators
A hormone synthesized and secreted by the thyroid gland containing four iodine atoms and is converted to triiodothyronine (T3) in the body, influencing metabolism and organ function.
Tests
Thyroxine is also called T4. T4 is a hormone that your thyroid gland makes. A T4 test measures the level of T4 in a sample of your blood. Too much or too little T4 may be a sign of a thyroid problem .
Indicators
A thyroid hormone containing 3 iodine atoms generally synthesized from levothyroxine, and has greater biological activity.
Tests
A triiodothyronine (T3) test measures the level of T3 in a sample of your blood. It's used to help diagnose thyroid disease .
Indicators
Thyroid-stimulating hormone — the pituitary signal that regulates the thyroid and the usual first test of thyroid function.
Tests
TSH stands for thyroid stimulating hormone . Another name for it is thyrotropin. A TSH test is a blood test that measures this hormone. A TSH level that is too high or too low may be a sign of a thyroid problem .
