An at-home finger-prick test measuring TSH and FT4, two markers commonly used to check thyroid function. Suited to people with symptoms such as fatigue, weight changes or mood changes.
2 biomarkers as listed by YorkTest.
The Thyroid Test measures thyroid-stimulating hormone (TSH) and free thyroxine (FT4), the two key markers commonly used to check how well the thyroid gland is functioning. YorkTest positions it for people experiencing symptoms such as low energy, unexplained weight changes, mood changes, dry skin or muscle aches.
Within its thyroid function comparison group, its £41 price sits 25% below the £54.90 group median, and is cheaper than six of the eight named peers, including MyHealthChecked's 2-marker Thyroid Profile Blood Test at £45 and Thriva's Baseline thyroid function blood test at £54.90. The only named peer cheaper is Monitor My Health's Thyroid Test at £32, which also includes a third marker, TPO antibodies.
It scores well for Value for money and for Trust signals, reflecting YorkTest's Trustpilot rating of 4.8 from 3,257 reviews, its UKAS-accredited lab, and 44 years of trading. It scores lower for Results and follow-up because, as with all YorkTest tests, results are not reviewed by a doctor as standard, though the listing does say it gives clear guidance on what to do next.
This suits people who want a focused two-marker thyroid check without paying the higher prices charged by most named peers. If price is the only factor, Monitor My Health's Thyroid Test at £32 is cheaper and includes a third marker (TPO antibodies). If you want the same two markers from a different provider at a similar price, MyHealthChecked's Thyroid Profile Blood Test is £45. It is not the right choice if you want a doctor to review your results as standard.
You take an at-home finger-prick blood sample and return it to YorkTest's laboratory, where TSH and FT4 are analysed. Results are provided as traffic-light values with clear guidance on what to do next, delivered within a stated 7 days. Results are not reviewed by a doctor as standard.
At £41, the Thyroid Test undercuts six of the eight named peers in its comparison group, sitting 25% below the £54.90 median. It measures TSH and FT4, the two key thyroid function markers; only Monitor My Health's 3-marker test at £32 is cheaper. Results are not reviewed by a doctor as standard.
