High thyroglobulin requires a combination of specific values and the patient’s own condition. Elevated thyroglobulin is caused by autoimmune thyroiditis. High thyroglobulin is commonly seen in patients with hyperthyroidism, toxic nodular goiter, subacute thyroiditis, and chronic lymphocytic thyroiditis. 1. If you are suffering from hyperthyroidism and have a high thyroglobulin test, it means that the treatment with thyroid medication is not effective and it is easy to relapse. 2. If you have thyroiditis, a high thyroglobulin test at this time will determine the cause of the disease and determine the specific treatment based on thyroid function. 3, if the thyroglobulin is a little high, generally do not need special treatment, but usually need to pay more attention to diet, quit smoking and alcohol, avoid eating spicy and stimulating food. If thyroglobulin is found to be high, it is recommended to check the function of the thyroid gland and then to perform a thyroid nuclear scan or a thyroid needle aspiration cytology to clarify the diagnosis and to exclude thyroid cancer, so that the treatment plan can be determined. When high thyroglobulin is detected, it should be treated aggressively to avoid any health consequences.
