TPO is an abbreviation for thyroperoxidase, an enzyme that plays a major role in thyroid hormone production and regulation. TPO is found in the thyroid gland, and it catalyzes the oxidation of iodide to form iodine, which is then used to form the hormones triiodothyronine (T3) and thyroxine (T4). TPO is also responsible for the production of hydrogen peroxide, which helps to regulate the levels of thyroid hormones in the body.
In health care, TPO is often used as a lab test to diagnose and monitor thyroid problems. It is especially useful in diagnosing Hashimoto's thyroiditis, an autoimmune disorder that affects the thyroid gland. TPO is also used to monitor patients with Graves' disease, a type of hyperthyroidism. In addition, TPO can be used to diagnose hypothyroidism, a condition in which the body does not produce enough thyroid hormones.
TPO is particularly important in diagnosing and managing thyroid conditions because it is a very sensitive marker of thyroid function. Elevated TPO levels can indicate that the thyroid is not functioning properly, while lower levels suggest that the thyroid is functioning normally. For example, TPO levels may be elevated in Hashimoto's thyroiditis, but not in Graves' disease. This can be important in determining the correct diagnosis and treatment.
In addition to diagnosing and managing thyroid conditions, TPO can also be used to monitor the effects of certain medications on thyroid function. For example, certain medications used to treat hyperthyroidism may also affect TPO levels. Monitoring TPO levels can help to ensure that the medication is working properly and that the thyroid is not being over- or under-stimulated.
What Are Normal TPO Levels?
The normal range for TPO levels is 0-34 IU/mL (international units per milliliter). Levels below 0 IU/mL are considered low, while those above 34 IU/mL are considered high. However, it is important to note that normal ranges vary depending on the laboratory and testing method used.
What Are High TPO Levels?
High TPO levels are generally considered to be above 34 IU/mL. High levels of TPO can indicate an overactive thyroid, or hyperthyroidism, as well as autoimmune disorders such as Hashimoto's thyroiditis. In addition, certain medications and environmental factors can also cause elevated TPO levels.
What Are Low TPO Levels?
Low TPO levels are generally considered to be below 0 IU/mL. Low levels of TPO can indicate an underactive thyroid, or hypothyroidism, as well as certain medications and environmental factors. In addition, low TPO levels can also be a sign of a healthy thyroid.
What Are the Treatment Options for Abnormal TPO Levels?
Treatment options for abnormal TPO levels depend on the underlying cause. For example, if the levels are high due to an overactive thyroid, then medications may be prescribed to reduce the levels. If the levels are low due to an underactive thyroid, then medications may be prescribed to increase the levels.
In addition, lifestyle changes such as reducing stress, eating a healthy diet, and getting regular exercise may also help to improve TPO levels. It is important to speak to a doctor or health care provider if abnormal TPO levels are suspected, as they can provide specific advice on treatment options.

What Is the Difference Between TPO and Thyroid Hormones?
TPO is an enzyme that plays a major role in thyroid hormone production and regulation. TPO catalyzes the oxidation of iodide to form iodine, which is then used to form the hormones triiodothyronine (T3) and thyroxine (T4). Thyroid hormones, on the other hand, are the hormones that are produced by the thyroid gland and are responsible for regulating metabolism.
What Is the Difference Between TPO and Thyroglobulin?
TPO is an enzyme that plays a major role in thyroid hormone production and regulation. Thyroglobulin, on the other hand, is a protein produced by the thyroid gland that stores iodine and helps in the production of thyroid hormones.
What Is the Difference Between TPO and Anti-TPO?
TPO is an enzyme that plays a major role in thyroid hormone production and regulation. Anti-TPO, on the other hand, is an antibody that is produced by the body in response to TPO. High levels of Anti-TPO can indicate an autoimmune disorder such as Hashimoto's thyroiditis.
Can TPO Levels Be Affected by Stress?
Yes, stress can have an effect on TPO levels. Chronic stress can increase the production of hormones like cortisol, which can interfere with the production of TPO and lead to elevated levels. It is important to manage stress in order to maintain healthy TPO levels.
