A blood test that measures thyroid peroxidase antibodies, commonly used to assess autoimmune activity against the thyroid gland.
1 biomarker as listed by Better2Know.
Thyroid peroxidase antibodies, often called Anti-TPO, are commonly used to assess whether the immune system is active against the thyroid gland, which can be relevant if you have symptoms such as fatigue, weight change or hair loss, a family history of autoimmune thyroid disease, or an enlarged thyroid. It is a single-marker test rather than a broader thyroid panel.
At £195, this is priced well above the only two other tests in our comparison group: Monitor My Health's version at £29 and Blue Horizon Medicals' at £45.25, both of which measure the same antibody. This gap is the main reason its value for money score is so low, even though it measures exactly what it sets out to.
Collection convenience is reasonable, since a home-visit nurse is offered as an alternative to a clinic trip, with results back within a day. Results and follow-up scores modestly because results are not doctor-reviewed as standard.
This suits people who have been advised to check thyroid antibody status, for example due to symptoms of thyroid dysfunction or a family history of autoimmune thyroid disease, and who want a clinic or nurse-visit option. If price matters more than that flexibility, Monitor My Health (£29) or Blue Horizon Medicals (£45.25) test the same single marker for much less. Speak to a GP about symptoms or an abnormal result.
A clinician takes a venous blood sample at a clinic appointment, or you can arrange a home visit from a nurse instead. The sample is sent to the lab, and you receive a report showing your antibody level against a reference range, typically within a day. Results are not doctor-reviewed as standard.
This £195 clinic blood test measures thyroid peroxidase antibodies, commonly used to assess autoimmune thyroid activity, and costs several times more than the only two rivals in our comparison group, priced at £29 and £45.25. Results are ready within a day, but there is no doctor review as standard.

A single-marker test measuring exactly what it sets out to; depth is not the point of this comparison group.
Requires a venous draw at a clinic; a home nurse visit is offered; results in around 1 days, well ahead of the thyroid norm of 2.
Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.

Cheapest standalone TPO antibody test we compare
A single blood test for TPO antibodies, used to help assess whether an underactive thyroid is likely to be caused by autoimmune disease.
Cheaper than Better2Know, pricier than Monitor My Health
This single-marker blood test checks thyroid peroxidase antibodies, an early marker of autoimmune thyroid disease. It suits people wanting a quick check for the antibodies linked to future thyroid problems, before or alongside a full hormone panel.
