Thyroid Peroxidase

Thyroid Peroxidase IgG 

This test is used to determine if an autoimmune thyroid disease is present, and to isolate it from being any other type of thyroid dysfunction.  This test may be used to investigate thyroid hormone levels when a patient is exhibiting signs of excessive or deficient thyroid hormone.  This test can also be used to see if thyroglobulin antibodies are interfering with thyroid cancer treatments.
