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.
4 biomarkers as listed by Monitor My Health.
This test measures thyroid stimulating hormone (TSH), free T4 and free T3, the three hormones that make up a standard thyroid function panel, plus TPO antibodies, which can indicate whether an underactive thyroid is likely to be caused by autoimmune disease.
Against the 14 tests in our advanced thyroid comparison group, this is the cheapest option, with a comparison-group median of £87.50 against its £42 price. It does carry fewer markers than some of the pricier peers, which test five or six markers rather than four, so it is a good fit if antibody testing is the main thing you want without paying for extras.
The scores reflect this trade-off. It scores strongly on value for money and on trust signals, helped by Monitor My Health's Trustpilot rating and its use of a UKAS ISO 15189 accredited NHS lab (Exeter Clinical Laboratory) that is CQC registered. It loses a little ground on clinical depth for having fewer markers than the group median, though clarity and collection convenience both score well, and results come with a doctor's review.
This suits anyone with possible thyroid symptoms, such as unexplained weight change, tiredness or a fast heart rate, who wants TPO antibody testing included rather than just the three core hormones. If you specifically want a deeper panel with more markers, peers such as Thriva's Advanced thyroid function blood test (£80.10, six markers) or Selph's Advanced Thyroid Test (£87, six markers) test more, at roughly double the price.
You collect a finger-prick blood sample at home and post it to Monitor My Health's laboratory, ideally Monday to Thursday to avoid weekend delays. The sample is analysed on a Roche Cobas e801 analyser, and results are typically available within 1 to 2 days of the lab receiving it. A doctor reviews the results and provides a written interpretation, including whether to see your GP if anything falls outside the expected range.
At £42 this is the cheapest test in our advanced thyroid comparison group, where the median price is £87.50. It covers four markers, against a group median of 5.5, so some peers test one or two markers more. Doctor review is included as standard.

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.
Widest thyroid panel in its group, at the highest price
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.
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.
At-home thyroid panel, £14 less than Randox's clinic test
An at-home blood test measuring TSH, Free T3, Free T4 and two thyroid antibodies, for people who want to check thyroid function without a clinic visit.
Broader thyroid panel priced 10% below the group median
A five-marker thyroid panel checking TSH, free T3, free T4 and two thyroid antibodies, going beyond a basic TSH and T4 check.
Joint-deepest thyroid panel here, but the priciest
Checks six thyroid markers, including TSH, T4, T3 and two thyroid antibodies, from an at-home finger-prick sample. Suited to people wanting a fuller picture than a basic TSH-only check.
1-day thyroid test, faster than Randox's home kit
A clinic-based blood test measuring TSH, Free T3, Free T4 and two thyroid antibodies, with results available within 24 hours.
Six-marker thyroid panel, priced above closest rivals
A 6-marker thyroid panel covering TSH, free T4, free T3, total T4 and two thyroid antibody tests, collected by a nurse. Suits people with thyroid symptoms wanting a fuller antibody check than a basic TSH test.
Priced above every named peer in its thyroid group
This blood test measures TSH, free T3, free T4 and reverse T3, giving a focused view of thyroid hormone status. It suits people already diagnosed with a thyroid condition who want ongoing monitoring rather than a first-time check.
Same marker count as rivals, at a far higher price
A 5-marker thyroid panel covering TSH, free T4, free T3 and two thyroid antibody tests, using a clinic or nurse-visit blood draw. Suits people with thyroid symptoms wanting antibody testing alongside the core hormones.
