Examples

  • After a patient's initial treatment, the standard follow-up includes periodic ultrasound exams of the neck as well as blood tests to measure thyroglobulin, a protein that is an excellent tumor marker for differentiated thyroid cancer.

    Glenn D. Braunstein, M.D.: Thyroid Cancer: The Facts

  • In one of the final steps involved in creating this pure thyroglobulin and assuring it was not altered, Rose injected that thyroglobulin—derived from rabbit thyroids—back into his rabbits.

    The Autoimmune Epidemic

  • They had produced antibodies to the thyroglobulin and developed lesions in their thyroids.

    The Autoimmune Epidemic

  • Your thyroid contains thyroglobulin protein, which binds to iodine to form hormones, which in turn influence essentially every organ, tissue and cell in your body.

    Dr. Joseph Mercola: A Newly Discovered Reason To Avoid Fast Food

  • Low serum thyroglobulin as a clue to the diagnosis of thyrotoxicosis factitia.

    The Neuropsychiatric Guide to Modern Everyday Psychiatry

  • This had the properties associated with a group of proteins called "globulins" and was therefore named thyroglobulin (thy'roh-glob'-yoo-lin).

    The Human Brain

  • (This can be done artificially, to a certain extent, by adding iodine to casein, as I mentioned above,) The thyroxine molecules are then united with other, more common amino acids and stored as the large thyroglobulin molecule.

    The Human Brain

  • At need, the thyroxine content of the thyroglobulin is stripped off and sent out into the bloodstream.

    The Human Brain

  • Preparations of thyroglobulin itself were 30 times or so as rich in iodine as was the intact thyroid gland and contained up to almost i per cent iodine.

    The Human Brain

  • For this reason it quickly seemed clear that thyroglobulin was at best merely the stored form of the hormone, and that what passed into the bloodstream were small fragments of the thyroglobulin molecule.
