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.
1 biomarker as listed by Blue Horizon Medicals.
Thyroid peroxidase antibodies (TPO antibodies) rise in the blood when autoimmune thyroid disease is present, often before thyroid hormone levels themselves shift. Testing for this single marker can flag a higher risk of future underactive or overactive thyroid before symptoms are obvious, which is why it works well as a stand-alone check or an add-on to a broader thyroid panel.
Priced at £45.25, this test lands almost exactly on the comparison group's median and is far cheaper than Better2Know's £195 equivalent, though pricier than Monitor My Health's £29 version of the same single-marker test. It does not test more than the one marker, but depth is not really the point of a targeted antibody check like this.
The strongest score here is for collection convenience, since the test can be done at home with a finger prick as well as via a venous draw at a clinic or a nurse visit, with results back in around 3 days. It also scores well for results and follow-up because a doctor reviews the outcome, and for trust signals reflecting Blue Horizon's Trustpilot rating, accredited labs and years of trading.
This is a sensible pick if you want a low-cost, fast check for thyroid autoimmunity, either because of a family history of thyroid disease or before committing to a fuller hormone panel. If cost is the only factor, Monitor My Health's Thyroid Peroxidase Antibody Test covers the same single marker for £29, though it is worth checking its own turnaround and collection options against this one.
This test can be collected at home with a finger-prick kit or a Tasso autodraw device, or via a venous draw at a clinic or with a nurse home visit. The sample is analysed for thyroid peroxidase antibodies, with a doctor reviewing the result and turnaround stated at around 3 days.
This is a single-marker test for thyroid peroxidase antibodies, used as an early flag for autoimmune thyroid disease before hormone levels change. At £45.25, it sits almost exactly on the median price for this comparison group, well below Better2Know's £195 version of the same test and above Monitor My Health's £29 one. Collection is flexible, with an at-home finger-prick option and results in around 3 days.
