What do high thyroid peroxidase antibodies indicate?
Welcome to justanswer and thank you for your question.
Well, Thyroid peroxidase (TPO) is an enzyme which is found in thyroid follicle cells where it converts the thyroid hormone T4 to T3.
Also, Moderate thyroid peroxidase levels may indicate that a patient has thyroid cancer, anemia, rheumatoid arthritis or Type 1 diabetes.
According to Mayo clinic- The presence of thyroid peroxidase antibodies in your blood suggests that the cause of thyroid disease is due to an autoimmune disorder such as Hashimoto's disease or Graves' disease.
Having High concentrations of thyroid peroxidase antibodies suggest the presence of Hashimoto's or Graves' Disease.

Do raised TPO mean hypothyroidism or hyperthyroidism or both?
Well, A high level of thyroid peroxidase means that a patient has Graves' disease or Hashimoto's disease.
And, In patients who have hypothyroidism, high TPO is indicative of Hashimoto's disease. In hyperthyroid patients, high TPO is indicative of Graves' disease.

This test - TPO will not tell if patient has Hypothyroidism or Hyperthyroidism.

In most cases, Thyroid-stimulating hormone (TSH): this is the single most useful lab test in diagnosing thyroid disease.
In case of hyperthyroidism, TSH level is Low, whereas in case of hypothyroidism, the TSH levels is high.
