Subclinical hypothyroidism: A high TSH level with normal T4 and T3 (liothyronine) levels suggest a diagnosis of subclinical hypothyroidism. Thyroglobulin levels may be normal in this setting. However I would check thyroid peroxidase antibodies and possibly TSH receptor antibodies to rule out underlying autoimmune thyroiditis. I am not sure what is meant by thyroglobulin antigen. Do you mean quantitative thyroglobulin level?
