Thyroglobulin dosage is an important test to monitor thyroid function. It helps to identify changes caused by benign diseases and also serves as an important marker during the treatment of thyroid cancer, to observe its evolution over time. When Thyroglobulin Dosage Is Indicated Dr Arthur Vicentini Bg When something is wrong in our body, changes in certain parameters occur. We noticed changes in cell counts, hormone rates, metabolism speed, enzymes, proteins, and others. Therefore, performing tests that count or measure these markers contributes in a certain way to diagnose a disease, or to monitor the evolution of a treatment. Thyroglobulin dosage is one of the controls that fits this scenario.
It contributes significantly to the treatment of thyroid cancer. Want to know more? Keep reading to delve deeper into the subject! Index What is thyroglobulin dosage? How does this test help in the treatment of thyroid cancer? When is thyroglobulin testing necessary? What is thyroglobulin dosage? The thyroid produces a series of hormones that regulate Whatsapp Number List the speed of our body's functioning. Some of the main ones are the T3 and T4 . During the production of these hormones, as a by-product of chemical reactions, there is concomitant production of a protein called thyroglobulin . As the cells of the most common malignant thyroid tumors (papillary carcinoma and follicular carcinoma) are very similar to the native cells of the gland, thyroglobulin is also often produced by them.
A thyroglobulin test is a type of blood test that helps measure how much of this protein is being produced by the body. In this way, after surgery to remove the thyroid gland, we can monitor the amount of thyroglobulin and identify changes in its levels evolutionarily. How does this test help in the treatment of thyroid cancer? You have seen that thyroglobulin is produced by the thyroid and by thyroid tumor cells. Therefore, after surgical treatment (with or without supplementation with radioiodine therapy), it is expected that thyroglobulin will be low , close to zero. In the follow-up of well-differentiated thyroid tumors (follicular and papillary carcinomas), the periodic dosage of thyroglobulin helps the physician to dynamically monitor the possibility of recurrence.
