Checks thyroid hormones and antibodies alongside vitamin D, ferritin and active B12, for people with possible thyroid symptoms or an existing thyroid condition to monitor.
9 biomarkers as listed by Thriva.
This test measures thyroid-stimulating hormone (TSH), thyroxine (T4), free thyroxine (FT4) and free triiodothyronine (FT3), together with two thyroid antibodies (TgAb and TPOAb). These markers are commonly used to assess how the thyroid gland is functioning and whether an under- or overactive thyroid could be contributing to symptoms such as fatigue, weight changes or low mood. The panel also includes vitamin D, ferritin and active B12, three nutrients that can independently affect energy levels.
Within our advanced thyroid function comparison group, this is the most detailed panel: 9 markers against a median of 5.5 across the 14 tests we compare it with. That extra depth comes at a cost. At £122.40 it sits well above the group median of £87.50, and above Thriva's own six-marker advanced thyroid test at £80.10.
It scores well for collection convenience, since you can test at home with a finger-prick kit or add a nurse visit, with results back in around two days, and for trust signals, reflecting Thriva's Trustpilot rating, lab accreditation, CQC registration and doctor review as standard. Its listing is also clear, setting out the full biomarker list, sample type and turnaround. Price is where it loses ground, given how far above the group median it sits.
This suits you if you want a wider check on thyroid health than a basic TSH test, including antibodies that can flag autoimmune thyroid activity, plus a look at vitamin D, ferritin and B12 status in the same sample. It works well if you are already having your thyroid monitored and want doctor-reviewed results with a fuller nutrient picture.
If you only want the core thyroid hormones without antibodies or nutrients, Thriva's own advanced thyroid function blood test covers 6 markers for £80.10, and other providers in this comparison group offer similar core panels from around £42 to £65. Choose this fuller test only if the antibody and nutrient markers are worth the extra cost to you.
This is a blood test. You can collect your own sample at home with a finger-prick kit, or pay an extra £60 for a nurse to take a venous sample. Once your sample reaches the lab, results are typically ready within 2 days, and a doctor reviews them before they are sent to you as part of your report.
This is a 9-marker thyroid panel covering TSH, T4, FT3, FT4 and thyroid antibodies, plus vitamin D, ferritin and active B12, reviewed by a doctor. At £122.40 it has more markers than any other test in this group, but costs well above the £87.50 group median, including Thriva's own smaller 6-marker thyroid panel at £80.10.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
9 biomarkers against a median of 5.5 across the 14 tests in its comparison group.
A finger-prick sample you take at home; with a venous or clinic option as well; a home nurse visit is offered; results in around 2 days, in line with or faster than similar tests.
Results are reviewed by a doctor; the provider does not describe the report format.

Cheaper than other six-marker thyroid panels
This test checks six thyroid markers, including TSH, FT3, FT4 and two thyroid antibodies, giving a fuller picture than a basic TSH check. It suits anyone wanting autoimmune thyroid markers included.
The only panel here testing both major thyroid antibodies
A 6-marker thyroid panel measuring TSH, free T3, free T4, total T4 and two thyroid antibodies (TPO and thyroglobulin), for people investigating possible autoimmune thyroid disease.
Mid-priced 5-hormone thyroid panel with antibodies
Tests TSH, free thyroxine, free T3 and two thyroid antibodies, extending the basic thyroid panel to look for autoimmune involvement. Suited to investigating thyroid symptoms or monitoring a known autoimmune thyroid condition.
Cheapest advanced thyroid test with antibodies
Measures TSH, FT4, FT3 and TPO antibodies from an at-home finger-prick sample, for anyone with possible thyroid symptoms who wants antibody testing alongside the standard hormone panel.
Mid-priced among the six-marker thyroid panels
This blood test measures thyroid hormones (TSH, free T4, free T3), thyroid antibodies and vitamin D. It suits anyone with possible thyroid symptoms who wants antibody testing included, not just hormones.
More markers than its peers, priced higher too
This panel measures TSH, free T3, free T4 and both thyroid antibodies, plus cortisol and magnesium at no extra cost. It suits people wanting a deeper thyroid check, including autoimmune antibodies, alongside monitoring an existing diagnosis.
