Thyroid Peroxidase antibodies

Three reasons the Thyroid Peroxidase Antibodies (Anti-TPO) test is right for you

• This test detects antibodies that target the thyroid gland, helping identify autoimmune thyroid disease
• It is useful for diagnosing conditions such as Hashimoto’s thyroiditis or Graves’ disease
• Early detection allows your healthcare provider to monitor thyroid health and intervene to maintain optimal hormone balance

What is the Thyroid Peroxidase Antibodies (Anti-TPO) test?

The Anti-TPO test measures antibodies in your blood that target thyroid peroxidase, an enzyme critical for thyroid hormone production. High levels of these antibodies indicate that your immune system is attacking your thyroid, which can lead to hypothyroidism or hyperthyroidism.

This test is often recommended for:

• Individuals with symptoms of thyroid dysfunction, such as fatigue, weight changes, or hair loss
• Patients with a family history of autoimmune thyroid disease
• People with unexplained goitre or enlarged thyroid
• Monitoring autoimmune thyroid activity in patients already diagnosed with thyroid disorders

What are the symptoms of autoimmune thyroid disease?

Symptoms can vary depending on whether the thyroid is underactive or overactive, and may include:

• Persistent fatigue or low energy
• Unexplained weight gain or loss
• Sensitivity to cold or heat
• Hair thinning, brittle nails, or dry skin
• Swelling at the front of the neck (goitre)
• Mood changes, palpitations, or tremors in some cases

How does the Thyroid Peroxidase Antibodies (Anti-TPO) test work?

A blood sample is taken and analysed for the presence of Anti-TPO antibodies. Elevated levels indicate autoimmune activity against the thyroid. These results help your clinician determine if thyroid dysfunction is immune-mediated and guide appropriate monitoring or treatment strategies.

What can I expect at my appointment?

Your appointment involves a standard blood draw performed by a trained healthcare professional. The procedure is quick, safe, and minimally invasive.

Results are typically available within 1 day. You will receive a report showing your Anti-TPO antibody levels, along with reference ranges and guidance on any further testing or management that may be required.

Are there any risks with this test?

This is a routine blood test and is very safe. Most people experience only mild discomfort at the needle site.

Minor bruising or tenderness may occasionally occur. Serious complications are extremely rare. Seek medical advice if you feel unwell after the test.
