The Prevalence of Serum Thyroid Hormone Autoantibodies in Autoimmune Thyroid Diseases
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.
