An at-home finger-prick test checking FT4 and TSH, the two core thyroid hormones, for people who want a thyroid function check without a clinic visit.
2 biomarkers as listed by Better2Know.
This kit measures two core thyroid markers: thyroid stimulating hormone (TSH), which signals the thyroid to produce more or less hormone, and free thyroxine (FT4), one of the hormones that regulates metabolism. Together they are commonly used to help assess whether the thyroid gland is underactive or overactive, and can be relevant if you have symptoms such as weight change, fatigue or low mood.
At £69, this is the most expensive two-marker test among the nine in its comparison group. MyHealthChecked (£45) and Thriva (£54.90) test the same two markers for less, while three-marker panels from Monitor My Health (£32), Medichecks (£45) and Selph (£55) cost less despite measuring an extra marker. Better2Know's own three-marker home kit is priciest overall at £199.
Clinical depth is about typical for its group, since two markers is the median among its nine peers. Collection convenience scores highly, since it can be done at home or at a clinic, with results back within a day. value for money is the main weak point given the cheaper alternatives above, and results and follow-up scores modestly because results are not doctor-reviewed as standard.
This suits people who specifically want TSH and FT4 checked at home without paying for a broader panel, for example for a quick baseline check or to monitor known thyroid medication. If you want the same two markers for less, MyHealthChecked (£45) or Thriva (£54.90) are cheaper options, and if you want an extra marker for a similar or lower price, Medichecks (£45) or Monitor My Health (£32) are worth considering. See a GP about symptoms or an abnormal result.
You collect a finger-prick blood sample at home using the kit provided and post it to the lab, where it is analysed for TSH and FT4. A clinic-based version of the same test is also available for £195 if you would rather have a professional blood draw. Results are typically ready within a day, and Better2Know's Patient Services team contacts you once they are available, alongside access through the secure patient login area. Results are not doctor-reviewed as standard.
This £69 at-home thyroid kit checks FT4 and TSH and is the most expensive two-marker option in a group of nine tests, though some three-marker rivals such as Medichecks (£45) cost less for more markers. Results are ready within a day, and there is no doctor review as standard.
