Description

Antibodies that attack the thyroid gland cause swelling, rarely tenderness and reduced function of the thyroid. Your doctor may also order a TPO antibody test if you are pregnant and have an autoimmune disease that involves the thyroid, such as Hashimoto's disease or Graves' disease. Some people with TPO antibodies may not have thyroid disease.

Overview

Overview

The Anti-Thyroid Antibody test measures the presence of antibodies that target the thyroid gland. These antibodies can interfere with thyroid function and are associated with autoimmune thyroid diseases such as:

  • Hashimoto’s thyroiditis – commonly leads to hypothyroidism

  • Graves’ disease – commonly leads to hyperthyroidism

Common types of anti-thyroid antibodies tested:

  • Anti-thyroid peroxidase antibody (Anti-TPO Ab) – indicates thyroid tissue damage, most common in Hashimoto’s.

  • Anti-thyroglobulin antibody (Anti-Tg Ab) – less specific, also seen in autoimmune thyroid diseases.

  • TSH receptor antibody (TRAb) – primarily in Graves’ disease.

 

Risk assessment

Risk Assessment

  • Minimal risk – this is a simple blood test.

  • Potential risks:

    • Slight pain or bruising at the puncture site.

    • Rare: infection at the puncture site.

  • Precautions:

    • No special precautions for fasting unless other tests are being done.

    • Inform the lab if on medications affecting thyroid function.

 

Ranges

Normal Range

Reference ranges can vary by lab. Typical values:

  • Anti-TPO Ab: < 35 IU/mL

  • Anti-Tg Ab: < 40 IU/mL

  • TRAb: < 1.75 IU/L

Test result interpretation

Interpretation

Antibody Positive Result Suggests Clinical Notes
Anti-TPO Ab Hashimoto’s thyroiditis, sometimes Graves’ Higher levels correlate with disease severity and risk of hypothyroidism
Anti-Tg Ab Hashimoto’s, Graves’, or thyroid cancer Less specific; used with Anti-TPO for confirmation
TRAb Graves’ disease May indicate hyperthyroidism; also important in pregnancy to assess fetal risk
