One of the thyroid tests you may be asked to take is a thyroid peroxidase test. This test is done to assess your thyroid peroxidase antibody range and detect any underlying autoimmune disease you may have such as Hashimoto’s thyroiditis or Graves’ disease. Find out more about this thyroid test to help your doctor give you a more accurate assessment of your thyroid!
7 Things About Thyroid Peroxidase Tests to Keep in Mind
1. Concerning Thyroid Peroxidase Enzyme
This thyroid test is mainly concerned with the thyroid peroxidase (TPO). TPO is an enzyme which helps the thyroid gland produce thyroid hormones. It can also be found in thyroid follicle cells to assist in the conversion of the thyroid hormone T4 to T3.
2. Monitoring TPO Antibodies
Specifically, this thyroid test monitors your TPO antibodies. These antibodies attack your thyroid gland and your TPO. Their presence in your bloodstream may mean you’re prone to thyroid disorders such as Hashimoto’s thyroiditis or Graves’ disease.
3. Diagnosing Your Thyroid
For a more accurate diagnosis of your thyroid health, combine your TSH test with other clinical tests. https://t.co/VYiLY1SwwJ

The thyroid peroxidase test is one of the many thyroid tests you can take to diagnose the condition of your thyroid. This specific test is more commonly taken to look for any autoimmune thyroid disease and to find the cause of your thyroid condition.
4. Different Names for TPO Test
The thyroid peroxidase test has a lot of other names such as thyroid peroxidase antibody (TPOAb) test, thyroid peroxidase autoantibody test, antimicrosomal antibody test, and antithyroid microsomal antibody test. It may be helpful to keep some of these names in mind to avoid any confusion.
5. TPO Test Procedure
The TPO test is a simple blood test which may not require any specific preparation. First, your physician will clean the surface of the skin, and then they will draw blood. This procedure takes only a few minutes and is relatively painless. Make sure you’re wearing short sleeves to ensure your veins are accessible.
6. Processing Your Blood Sample
After your blood has been taken, the sample will be examined using a machine. The results usually take several days to process but will be available and sent to your doctor a few days after the procedure. Your doctor will then give you an interpretation of your TPO test results.
7. TPO Tests Results
The results of your TPO test may show positive for antibodies if you have chronic thyroiditis. It can also indicate other autoimmune disorders such as lupus, rheumatoid arthritis, pernicious anemia, and Sjogren’s syndrome. There are also cases where positive test results show no other signs of a thyroid disorder.

A TPO test is a useful thyroid test to diagnose the condition of your thyroid and if you have any underlying thyroid conditions such as Hashimoto’s thyroiditis or Graves’ disease. Positive results of your TPO test may also show no other evidence of a thyroid disorder. Much like a TSH test and thyroid biopsy, taking more than one thyroid test may help your doctor give you a more accurate diagnosis of your thyroid health.
