The Prevalence of Serum Thyroid Hormone Autoantibodies in Autoimmune Thyroid Diseases

Thyroid hormone autoantibodies(THAA) in serum can Interfere radioimmunoassay for the determination of free thyroid hormones. Thyroid function test plays a key role in the diagnosis and treatment of autoimmune thyroid disease (AITD), and abnormal examination results in misdiagnosis and mistreatment. At present, the epidemiological results of THAA in AITD are inconsistent, and the pathogenesis has not been clarified. However, there is no relevant research on THAA in China. This project intends to collect AITD patients and healthy people, detecting THAA, at the same time testing thyroid function and thyroid autoantibodies, definiting positive rate of THAA in AITD patients, observing the effect of common therapeutic drugs for AITD on THAA, investigating the rule of THAA influencing thyroid function test results .This project will provide the basis and method for how to effectively avoid THAA interfering with thyroid function test.
