Thyroglobulin antibody is a common autoantibody found in the serum of patients with autoimmune thyroid disease. Its results are important for the diagnosis and treatment of thyroiditis, especially Hashimoto’s thyroiditis. The cost of having a thyroglobulin antibody test is about$80-150. The fee varies from region to region and hospital level to hospital level, so it is not possible to have a uniform price nationwide. The anti-thyroglobulin antibody is an autoantibody caused by thyroiditis and is a specific diagnostic indicator of chronic lymphocytic thyroiditis. Secondly it is also clinically important for the diagnosis of primary hypothyroidism. Therefore, a test for thyroglobulin antibodies can clearly diagnose the presence of chronic lymphocytic thyroiditis or primary hypothyroidism. Patients only need to take 2-3 ml of venous blood on an empty stomach and the results will be available within one working day. At this stage, the main method of thyroglobulin antibody test is chemiluminescence, because of the improvement of the test method, so the cost will be increased to varying degrees, if the ELISA method will cost much less, but this method is now gradually eliminated. In fact, if you go to a regular hospital for thyroglobulin antibody testing, the cost difference is not great and the overall cost is not high, so there is no need to get too hung up on the cost.
