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.
5 biomarkers as listed by Randox Health.
This test measures thyroid-stimulating hormone (TSH), Free T3 and Free T4, along with the Anti-TPO and Anti-TG antibodies. These markers are commonly used to assess whether symptoms such as fatigue, weight changes, anxiety, poor sleep or sensitivity to temperature could be linked to thyroid function, since the thyroid plays a role in energy levels, mood and metabolism. Persistent symptoms are worth discussing with a GP alongside any test result.
Against the 14 tests in its comparison group, this one is priced 47% below the £87.50 median. Monitor My Health's Advanced Thyroid Test is cheaper still at £42, though it covers one fewer marker (4 versus 5). Randox's own clinic-based Thyroid Function Test costs £14 more, at £60, but returns results in 1 day rather than 2 to 3.
The scores reflect strong value with a modest speed trade-off. Value for money is very strong at 47% below the group median. Collection convenience scores well since it can be done at home, though total time including postage runs a little longer than the 2 to 3 day lab processing window. Clinical depth sits close to the group median of 5.5 markers. Results and follow-up scores lower since results are not reviewed by a doctor as standard.
This suits people who want to check thyroid function without visiting a clinic and do not mind waiting a day or two longer than the clinic option. If speed matters most, Randox's own clinic-based Thyroid Function Test returns results in 1 day for £60. If the lowest possible price matters more than one extra marker, Monitor My Health's Advanced Thyroid Test is £42. Anyone with ongoing symptoms should also consider seeing a GP.
You use the QuickDraw Premium kit at home, which draws blood from the upper arm using the Tasso+ device rather than a finger-prick. You post the sample to the lab, and results covering all 5 markers are available within 2 to 3 working days of arrival, though they are not reviewed by a doctor as standard.
This at-home test measures 5 thyroid markers, TSH, Free T3, Free T4, Anti-TPO and Anti-TG, using a device that draws blood from the upper arm. At £46 it comes in 47% below the £87.50 median for its comparison group, and £14 less than Randox's own clinic-based version, though results take a day or two longer. It is not reviewed by a doctor 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.
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.
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.
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.
