Patients recovering from recent illness or those taking drugs such as glucocorticoids or opiates may have suppressed TSH, but free thyroid hormone levels will be normal or low. To exert its effects, T4 is converted to triiodothyronine (T3) by the removal of an iodine atom. Background: Thyroglobulin antibodies (TgAb) are produced by 10%-25% of thyroid cancer patients and interfere with thyroglobulin measurement, a marker of residual or recurrent cancer after surgery. Therefore, this activity can be measured by having an individual swallow a small amount of iodine, which is radioactive. The detection of antithyroid antibodies, specifically of antithyroglobulin antibodies, in patients with differentiated thyroid carcinoma after near-total thyroidectomy, radioiodine therapy and thyroxine suppression presents difficulties in screening patients for residual disease or recurrence of the disease as it may interfere with thyroglobulin measurement. In addition to the radioactive iodine uptake, a thyroid scan may be obtained, which shows a picture of the thyroid gland and reveals what parts of the thyroid have taken up the iodine (see Thyroid Nodules brochure).

Some people with TPO antibodies may not have thyroid disease. Additionally, TgAb+ positive patients were also stratified into those with persistent TgAb elevation and those without.
