A two-marker at-home blood test checking TSH and free T4, for a first look at possible underactive or overactive thyroid function.
2 biomarkers as listed by London Medical Laboratory.
TSH and free T4 are the two markers most commonly used as a starting point for assessing whether the thyroid gland is underactive or overactive. Both can be affected well before more obvious symptoms appear, which is why this pairing is often used as a first check rather than a final answer.
There is no named comparison group on record for this specific test, so it is scored against the wider set of thyroid tests we track. On that basis its two-marker depth places it around the 30th percentile for biomarker count, while its £49 price sits roughly 10% below the £54.58 median for similarly sized thyroid tests.
Collection convenience scores highly because the test can be done entirely at home, and trust signals reflect the provider's CQC registration and doctor-reviewed report as standard.
This is a reasonable first check for anyone with possible thyroid symptoms who wants a quick, low-cost, at-home option, and it is worth discussing any symptoms with a GP alongside testing. If you want antibody testing as well, in case an autoimmune cause is suspected, London Medical Laboratory's own Thyroid Full Profile checks five markers for £79.
This is a blood test. You can use an at-home finger-prick kit (£3.99 postage), attend a partner clinic for a venous draw (£35), or arrange a phlebotomist home visit. Results are typically ready within a day and are reviewed by a doctor.
This £49 test checks just TSH and free T4, a first-line pair commonly used to assess thyroid function. It is narrower and cheaper than London Medical Laboratory's own five-marker Thyroid Full Profile, and it can be done with an at-home finger-prick kit rather than a clinic visit.

2 biomarkers, placing it in the 29th percentile of thyroid tests we track.
A finger-prick sample you take at home; with a venous or clinic option as well; results in around 1 days, well ahead of the thyroid norm of 2.
Results are reviewed by a doctor; the provider does not describe the report format.
No Trustpilot rating on record; CQC registered; doctor review as standard.
