What does it mean when your thyroid peroxide level is at an 11?

A thyroid peroxidase (TPO) level of 11 indicates the presence of thyroid antibodies in the bloodstream, which may suggest an autoimmune thyroid condition, such as Hashimoto's thyroiditis or Graves' disease. Normal TPO levels typically range from 0 to 9 IU/mL, so a level of 11 could indicate mild thyroid inflammation or dysfunction. It's important to discuss these results with a healthcare provider for proper interpretation and potential follow-up testing.
