An assay method for TSH-R autoantibodies or TSH comprises contacting a test sample, in the presence or absence of TSH, with cells from a clone expressing human TSH-R transfected with a reporter construct comprising cDNA of both (i) a reactant, such as an enzyme, capable of causing a ...
Thyroid peroxidase (TPO) is an enzyme made in the thyroid gland that is important in the production of thyroid hormones.TPO is found in thyroid follicle cells, where it converts the thyroid hormoneT4 to the thyroid hormone T3. TPO also facilitates the binding ofiodineto proteins within the t...
Unfortunately, not all cases are as straightforward as this, which is why I will go over the other optimal thyroid lab studies below and help explain why you may have “normal” thyroid lab tests but still be symptomatic. Bottom line: The presence of elevated anti-TPO antibodies is always a...

TPO Antibodies test is often ordered when a person has symptoms of thyroid disease, especially if they have had irregular results from other thyroid tests, to help diagnose the cause. Pregnant women with autoimmune disorders often have a TPO Abs test done to help determine if their infant will...
Illustration by Michela Buttignol for Verywell Health If you have an autoimmune thyroid disorder, your blood levels of TPO antibodies can increase and can be detected with a simple blood test. Further testing may be needed to determine the cause and offer a diagnosis. ...
What is the antibody test for Graves' disease? Graves' disease It is an autoimmune disease in which our own immune cells attacks on thyroid gland leading to increased thyroid hormone levels that cause several complications like fatigue, anxiety, irritability, bulging of eyes, increased size of thy...
TPO was prepared from Graves' thyroid glands, solubilized by n-octyl glucoside, and its activity was assayed by the guaiacol method. Control sera and sera with a positive microsomal hemagglutination test (MCHA(+) ) were assayed for their ability to precipitate TPO activity by incubation of sera...
