A single blood test for TPO antibodies, used to help assess whether an underactive thyroid is likely to be caused by autoimmune disease.
1 biomarker as listed by Monitor My Health.
TPO (thyroid peroxidase) antibodies are made by the immune system against a protein inside the thyroid gland. Raised levels can indicate that an underactive thyroid, or a mild subclinical form of it, is caused by autoimmune disease, and the provider notes that repeat testing is not usually worthwhile since antibody levels are not closely tied to changes in the condition.
Within our small, two-peer thyroid antibodies comparison group, this test's £29 price is well below both Blue Horizon Medicals (£45.25) and Better2Know (£195), all three testing the same single TPO marker.
Scores here are led by value for money, given the gap to both peers, and by the trust and process factors common across the provider's range.
This suits anyone who has already had thyroid hormone tests showing a subclinical or borderline pattern and wants to know whether TPO antibodies are present, at the lowest price of the tests we track for this marker. It is not intended to be repeated regularly, since the provider says antibody levels do not track disease change closely enough to be useful for monitoring.
You take a finger-prick blood sample at home and post it Monday to Thursday. The lab runs the Roche Cobas Elecsys Anti-TPO immunoassay, and results are typically available within 1 to 2 days, reviewed by a doctor who explains what a positive or negative result means for you.
At £29, this is well below both peers in our thyroid antibodies comparison group: Blue Horizon Medicals' £45.25 test and Better2Know's £195 test, a group median of £45.25. All three test the same single TPO marker.

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.
Costs far more than its two thyroid-antibody rivals
