![]() ![]() It is usual for a small amount to enter the bloodstream, but if larger quantities are present outside the thyroid, something is often wrong. Thyroglobulin is made by follicular cells in the thyroid and generally stays in the thyroid. Too much iodine can create toxicity symptoms like stomach pain, nausea and vomiting, or neurological dysfunction. Iodine is essential for the proper functioning of our thyroid gland, and a deficiency in this nutrient is a risk factor for hypothyroidism (underactive thyroid). Thyroglobulin fluctuates with iodine levels, and elevated levels of Tg may indicate iodine deficiency or excess. Thyroglobulin (Tg) is a large protein secreted by the thyroid gland that helps produce and store thyroid hormones T4 and T3. If your TSH level is above the normal range, it is worthwhile to check your antibodies to determine if Hashimoto's is the cause of your underactive thyroid condition.Īnother test used to determine thyroid autoimmunity is TgAb or thyroglobulin antibodies. It is also helpful to test T3 (triiodothyronine the active form of thyroid hormone) and autoimmune markers like thyroperoxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb). TSH and T4 tests alone will likely not give you or your doctor a complete idea of what is going on with your thyroid function. T4 (thyroxine) is the measurement that tells you how much thyroid hormone is circulating in your blood.Īlmost all instances of overt hypothyroidism and subclinical hypothyroidism in the United States are caused by Hashimoto's disease, marked by elevated TPO antibodies. TSH (thyroid-stimulating hormone) comes from the pituitary gland in your brain and tells the thyroid how much thyroid hormone to make. Most hypothyroid patients who regularly have thyroid tests will likely recognize TSH and T4. And, if you do have a thyroid condition, you must understand what each lab value can tell you about your thyroid. Therefore, several tests run on a blood sample is necessary to get the whole picture of what is happening to this small but mighty organ. No single test tells you everything you need to know about your thyroid function. What if you have high Tg antibodies but normal TPO antibodies?. ![]()
