Thyroid Test
Cheapest full 3-hormone thyroid panel
A three-hormone blood test measuring TSH, FT4 and FT3, the standard panel used to check for an underactive or overactive thyroid.
- At-home test
A six-marker panel combining adrenal hormones (cortisol, DHEA sulphate), the main sex hormones and core thyroid markers (FT4, TSH). Suited to anyone wanting a broader look at how these interlinked hormone systems are functioning together.
6 biomarkers as listed by Blue Horizon Medicals.
This test measures six hormones across three connected systems: cortisol and DHEA sulphate from the adrenal glands, oestradiol and testosterone as the main sex hormones, and FT4 and TSH from the thyroid. The provider frames this as a way of looking at the hypothalamic-pituitary-adrenal axis as a whole, since these hormones influence each other: cortisol is converted into DHEA sulphate, which in turn feeds into testosterone and oestradiol production, while a normal TSH result is used to assess whether the pituitary gland is functioning well enough to support healthy adrenal control.
Against the 24 similarly sized thyroid tests we track, this panel is priced close to the median, around 2% below the typical £83.55 price point, so it isn't a premium or a bargain option in its size bracket.
It scores well for clinical depth, since six biomarkers puts it in the upper range for thyroid-category tests we track, and for clarity and documentation, as the listing sets out the full biomarker list, sample type, turnaround and collection options in detail. It also scores well for results and follow-up because a doctor reviews the results. It scores lower for collection convenience, since it needs a venous blood draw at a clinic, though a home nurse visit is offered as an alternative. Blue Horizon Medicals works with UKAS ISO 15189 partner labs and has been trading since 2009.
This suits you if you want a single test covering adrenal, sex hormone and thyroid markers together, for example if you're investigating fatigue or hormonal symptoms that could stem from any of these interlinked systems rather than one obvious cause. Because it requires a venous blood draw, it's less convenient than an at-home finger-prick kit; a home nurse visit is available if you can't get to a clinic. We don't have a directly comparable multi-system panel from another provider in our catalogue, so we can't say whether a cheaper alternative exists elsewhere for this exact combination of markers.
A trained professional takes a venous blood sample at a clinic, or a nurse can visit your home for the draw. The fact sheet doesn't detail what happens to the sample once it reaches the lab beyond processing for the six listed markers. Results are typically back within 1 day, and a doctor reviews them before they reach you.
Six markers spanning adrenal function (cortisol, DHEA sulphate), core sex hormones (oestradiol, testosterone) and thyroid status (FT4, TSH) are combined in this single blood draw. At £82.25 it sits close to the median price for similarly sized thyroid tests we track, about 2% below typical. The main caveat is that it requires a venous blood draw rather than a home finger-prick kit.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
6 biomarkers, placing it in the 79th percentile of thyroid tests we track.
A blood sample taken at home by a visiting nurse or phlebotomist; with a venous or clinic option as well; a home nurse visit is offered; 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.
