Checks thyroid stimulating hormone (TSH) alone, commonly used to see whether thyroid hormone levels, or a thyroxine replacement dose, are in the expected range. Suits routine monitoring rather than a first, broader thyroid check.
1 biomarker as listed by Blue Horizon Medicals.
This test measures TSH (thyroid stimulating hormone) alone. TSH is produced by the pituitary gland and is commonly used as a first check on thyroid function, and to monitor whether a thyroxine replacement dose remains at the right level over time.
As a single-marker test, it sits at the narrow end of our thyroid comparison group: 1 biomarker against a median of several across the tests we track, so it isn't designed to give a full thyroid picture. The only directly comparable peer we track, MyHealthChecked's Thyroid Stimulating Hormone (TSH) Rapid Test, covers the same single marker for £10, well below this test's £45.25.
It scores at the top of our scale for collection convenience, since it can be done with an at-home finger-prick or Tasso autodraw as well as a clinic or nurse visit, with results back within a day. It also scores well for documentation and for results and follow-up, since a doctor reviews the result. Blue Horizon has traded since 2009, holds a Trustpilot score of 4.2 from 395 reviews, and uses UKAS ISO 15189 partner labs.
This suits people who already know they need a TSH check, such as those monitoring a stable thyroxine replacement dose, and who want a quick, flexible collection option with a doctor review of the result.
If you want the same single TSH marker for less and don't need the doctor review or flexible collection options, MyHealthChecked's Thyroid Stimulating Hormone (TSH) Rapid Test is £10. If you want a broader first look at thyroid function rather than TSH alone, a multi-marker thyroid panel would tell you more.
You can collect your own sample at home with a finger-prick kit or a Tasso autodraw device, or have a venous draw at a clinic or by a home nurse visit. The sample is tested for TSH, with results back within a day, and a doctor reviews the result before you receive it.
This is a single TSH test priced at £45.25, with home finger-prick, Tasso autodraw, clinic and nurse-visit collection all available and results back within a day. It costs substantially more than MyHealthChecked's equivalent single-marker TSH test at £10, though it comes with a doctor review and more collection choices. If you only need a single TSH reading, it's worth weighing that price gap first.
