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.
Though a thyroglobulin test alone cannot be used to diagnose cancer, it can give you and your provider valuable information about any thyroid cancer you already have.
