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
This panel covers the three core thyroid hormones, both thyroid antibodies, and five extra markers including vitamin D, active B12, folate, ferritin and CRP. It suits people wanting a wide thyroid and general-health check in one sitting.
12 biomarkers as listed by Blue Horizon Medicals.
This panel tests the standard thyroid hormones and both thyroid antibodies (TPO and thyroglobulin) that flag autoimmune thyroid disease, then adds five further markers: vitamin D, active vitamin B12, folate, ferritin and C-reactive protein, alongside cortisol and magnesium. The provider frames the added markers as covering general health issues that often overlap with thyroid symptoms, such as fatigue or low mood.
There is no named comparison group for this exact combination, so it is not measured here against specific rival products. Against the wider set of similarly sized thyroid tests we track, its £136.25 price is 38% above the median of £99.00, though it also sits in the 93rd percentile for the number of markers included, so the higher price tracks a wider panel rather than the same content at a premium.
It scores at the top of the range for clinical depth and for collection convenience, since it can be done at home with a finger prick and results come back in around a day. Value for money is the weakest score here, reflecting the price gap to similarly sized panels, while trust signals and results and follow-up both score solidly on the back of the doctor review and Blue Horizon's track record.
This suits someone who wants thyroid hormones, thyroid antibodies and a handful of general-health markers checked together, rather than ordering separate tests. If you only need the core hormones and antibodies without the extra vitamins and inflammation marker, Blue Horizon's own Thyroid Premium Silver profile covers those seven markers for £124.25.
Collection can be done at home with a finger-prick kit or Tasso autodraw device, or via a venous draw at a clinic or nurse home visit; the provider recommends taking the sample between 8am and 10am for a more reliable cortisol reading. All 12 markers are processed by the lab and a doctor reviews the results, with turnaround stated at around 1 day.
This 12-marker test combines TSH, free T3, free T4 and thyroid antibody testing with vitamin D, active B12, folate, ferritin, CRP, cortisol and magnesium. At £136.25, it costs 38% more than the median for similarly sized thyroid tests we track, though it also carries more markers than most of them. Results are back in around a day, reviewed by a doctor.
