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.
5 biomarkers as listed by Medichecks.
This test measures the same three core thyroid hormones as a standard panel, TSH, free thyroxine and free T3, and adds two antibody markers: thyroid peroxidase antibodies and thyroglobulin antibodies. These antibodies are commonly used to look into whether an autoimmune process is affecting the thyroid, alongside investigating symptoms or monitoring an existing diagnosis.
Within its 14-test comparison group, this sits in the lower-middle of the market on price at £65, below the £87.50 median, though Randox Health offers the same five markers for less, at £46 and £60. Tests that add a sixth marker, from Thriva, Selph, Numan and LetsGetChecked, cost more, from £80.10 up to £99.
The scores show clinical depth as roughly in line with the group median rather than a stand-out, since 5 markers is close to the median of 5.5, while value for money scores well given the below-median price. It scores full marks for collection convenience, with finger-prick, nurse-visit and clinic options and results in around 2 days, and well on trust signals thanks to Medichecks' Trustpilot record and its UKAS ISO 15189 partner labs.
This suits people who want to check for autoimmune involvement in thyroid symptoms, or who are monitoring a condition where antibody levels matter, rather than just the core hormone levels. It is also a reasonable step up from a basic thyroid check if initial results raised questions about antibodies.
If price is the main concern and you are comfortable using a different provider, Randox Health tests the same five markers for £46 or £60, both below this test's £65. If you only need the three core hormones without antibodies, Medichecks' own Thyroid Function Blood Test covers that for £45.
You can give a sample by at-home finger-prick, or have blood drawn at a Medichecks clinic or via a home nurse visit. The lab tests for TSH, free thyroxine, free T3, thyroid peroxidase antibodies and thyroglobulin antibodies, and a doctor reviews the results before you receive them. Medichecks states a turnaround of around 2 days.
This five-marker panel adds thyroid peroxidase and thyroglobulin antibodies to the standard TSH, free T3 and free thyroxine tests, for £65. That sits below its comparison group's £87.50 median, though two Randox Health tests offer the same five markers for £46 and £60. Results are doctor-reviewed and take around 2 days.

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.
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.

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
