A clinic-based blood test measuring TSH, Free T3, Free T4 and two thyroid antibodies, with results available within 24 hours.
5 biomarkers as listed by Randox Health.
This test covers thyroid-stimulating hormone (TSH), Free T3, Free T4, and the Anti-TPO and Anti-TG antibodies. The provider links these markers to symptoms such as fatigue, weight gain or loss, low mood, hair thinning, anxiety, palpitations and sensitivity to heat or cold, describing them as commonly linked to an underactive or overactive thyroid. If symptoms are ongoing, a GP visit alongside any test result is a sensible next step.
Among the 8 comparable thyroid tests in our data, this one is priced 31% below the £87.50 median, undercutting Medichecks (£65), London Medical Laboratory (£79), Thriva (£80.10), Selph (£87), Numan (£88) and LetsGetChecked (£99). It costs more than Monitor My Health's 4-marker test (£42) and Randox's own at-home Quickdraw version of this same 5-marker panel (£46), which is £14 cheaper but takes 2 to 3 days rather than 1.
The scores show a fast, well-priced option. Value for money is strong at 31% below the group median. Clinical depth sits close to the group median of 5.5 markers. Collection convenience benefits from the 24-hour turnaround, though it still requires a clinic visit. Results and follow-up scores lower since results are not reviewed by a doctor as standard.
This suits people who want the fastest possible thyroid results and do not mind visiting a clinic. If avoiding a clinic visit matters more than speed, Randox's own at-home Quickdraw version tests the identical 5 markers for £14 less, just a day or two slower. If price matters most and one fewer marker is acceptable, Monitor My Health's Advanced Thyroid Test is £42.
You attend a Randox Health clinic for a venous blood draw. The sample is sent to the lab, and results covering all 5 markers are available within 24 hours of arrival, though they are not reviewed by a doctor as standard.
This clinic-based test measures the same 5 thyroid markers as Randox's at-home version, TSH, Free T3, Free T4, Anti-TPO and Anti-TG, with results in 24 hours. At £60 it sits 31% below the £87.50 median for its comparison group, though it costs £14 more than Randox's own at-home Quickdraw kit for the identical panel. 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.
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.
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.
