Thyroid Peroxidase Antibodies (TPOab)

What are thyroid peroxidase antibodies (TPOab)?

Thyroid peroxidase antibodies (TPOab) are proteins produced by the immune system that attack thyroid peroxidase, an enzyme involved in the production of thyroid hormones. The presence of TPOab in the body can indicate autoimmune thyroid disease, such as Hashimoto's thyroiditis.

How are TPOab levels measured in the body?

TPOab levels can be measured in the body through a blood test.

What is the normal range for TPOab levels in the body?

The normal range for TPOab levels in the body is typically less than 9 international units per milliliter (IU/mL).

What can cause high TPOab levels in the body?

High TPOab levels can be caused by autoimmune thyroid disease, such as Hashimoto's thyroiditis.

How is an abnormal TPOab level diagnosed?

An abnormal TPOab level is typically diagnosed through a blood test. Other tests, such as a thyroid function test or imaging studies, may also be performed to evaluate thyroid function and identify any underlying thyroid disorders.

How is an abnormal TPOab level treated?

The treatment for an abnormal TPOab level depends on the underlying cause. If the abnormal TPOab level is caused by autoimmune thyroid disease, treatment may involve medications to regulate thyroid hormone levels and manage the autoimmune process. If the abnormal TPOab level is caused by another medical condition, such as an infection or cancer, treatment may involve addressing the underlying condition.
