One of the many manifestations when one has certain problems with the thyroid gland is an elevation of thyroglobulin. Elevated thyroglobulin is usually due to thyroid damage caused by thyroid biopsy, trauma, surgery, extensive bleeding, radiation damage, and inflammatory irritation. Of course, elevated thyroglobulin can also be caused by problems with the autoimmune system. If the thyroid function test is not abnormal, there is usually nothing wrong with this condition and there is no need to worry too much. When the thyroid gland is too hyperactive or too hypothyroid, there is a possibility of a combination of high thyroglobulin antibodies or increased thyroid peroxidase antibodies. Sometimes excessive iodine intake can also cause a high thyroglobulin level. Some women with diffuse goiter and poor immunity can also have high thyroglobulin. In addition, follicular carcinoma of the thyroid gland and papillary thyroid carcinoma can also cause high thyroglobulin. If you have a high thyroglobulin, it is important to check the function of the thyroid gland. High thyroglobulin needs to be treated with the help of a doctor to identify the cause.
