Tg
This test measures the amount of thyroglobulin (Tg) in the blood. Tg is a
protein produced by follicle cells in the thyroid gland.
Cells in the follicles produce and store Tg, breaking it down as needed
into the thyroid hormones T4 (thyroxine) and T3 (triiodothyronine). The
production of these hormones and their release into the blood stream is
stimulated by the pituitary hormone TSH (thyroid stimulating hormone).
The Tg test is primarily used as a tumor marker to evaluate the effectiveness of treatment for thyroid cancer and to monitor for recurrence. Not every thyroid cancer will produce Tg, but the most common types (papillary and follicular thyroid cancer) that arise from the follicle cells frequently do - resulting in increased levels of Tg in the blood. Tg may be ordered, often along with a TSH test, prior to thyroid cancer treatment to determine whether the cancer is producing Tg.
