What do we test for?

Thyroglobulin Antibodies (TgAb)

Thyroglobulin antibodies target thyroglobulin, a key protein in thyroid hormone production. Elevated levels may indicate autoimmune thyroid conditions like Hashimoto’s thyroiditis.

Thyroid Peroxidase Antibodies (TPOAb)

Thyroid Peroxidase antibodies attack the TPO enzyme, critical for thyroid hormone synthesis. High TPOAb levels suggest autoimmune thyroid disease, including Hashimoto’s and Graves’ disease.

How will this help you?

What is the Thyroid Antibodies Blood Test?

This home blood testing kit measures two key thyroid autoantibodies—Thyroglobulin Antibodies (TgAb) and Thyroid Peroxidase Antibodies (TPOAb)—to help detect autoimmune thyroid conditions such as Hashimoto’s thyroiditis or Graves’ disease. Ideal for anyone wanting to test for thyroid antibodies at home or understand the cause of thyroid symptoms.

How the Sample is Collected

Our home blood testing kit uses a self-collected finger-prick method. You will:

  1. Clean your fingertip and use the lancet provided
  2. Collect a few drops of blood into the small-volume TDL Tiny tubes
  3. Seal, label, and mail the sample in the pre-paid envelope

Results are typically available within 2–5 working days after the lab receives your sample.

Frequently asked questions

Can I test for thyroid antibodies at home?

Yes. Our home blood testing kit for thyroid antibodies allows you to collect a small finger-prick sample at home, then send it to our partner lab for analysis of Thyroglobulin and Thyroid Peroxidase antibodies.

How accurate is the at-home thyroid antibody blood test kit?

Our at-home blood tests use FDA-approved methods in a UK-accredited laboratory. When you follow the instructions for the TDL Tiny kit, results for Thyroglobulin and TPO antibodies are highly accurate and reliable.

How to test Thyroid Peroxidase antibody levels at home?

Collect your sample by following the step-by-step guide included with your blood test kit. You’ll perform a quick finger-prick using the TDL Tiny lancet, fill the small tubes, and post them back to the lab. Results are typically available within 2–5 working days.

What do high Thyroglobulin antibody levels mean?

Elevated Thyroglobulin antibodies (TgAb) often indicate autoimmune reactions against the thyroid gland, such as Hashimoto’s thyroiditis or, less commonly, Graves’ disease. Your GP can interpret results alongside symptoms and other hormone levels.

When should I do a home blood test kit for thyroid antibodies?

We recommend testing if you experience fatigue, unexplained weight changes, neck swelling, or family history of thyroid autoimmunity. A home blood test kit for thyroid antibodies provides early insight and guides further GP-led care.
