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 pairs the core thyroid hormones with iron, key vitamins and inflammation markers for a wider look at symptoms that can overlap with thyroid problems. It suits people who want more than a bare thyroid check in a single sitting.
14 biomarkers as listed by Blue Horizon Medicals, of 15 in total.
This test pairs the standard thyroid hormones (TSH, free T3 and free T4) with markers many people ask about alongside thyroid symptoms: iron and ferritin, vitamin B12, folate, vitamin D, cortisol and C-reactive protein, plus the antibodies linked to autoimmune thyroid disease. Cortisol and thyroid function can each affect the other, which the provider gives as the reason for testing them together rather than in isolation.
There is no named comparison group for this specific combination, so it cannot be measured directly against rival products. Against the wider set of similarly sized thyroid tests we track, though, its £149.25 price sits above the median of £124.25, which is reflected in a middling value-for-money score even though the marker count itself is unusually high.
It scores at the top of the range for clinical depth, placing it in the 95th percentile of thyroid tests we track for the number of markers included, and for collection convenience, since it can be done at home with a finger prick and results are back in around a day. It also scores well for trust signals and for having a doctor review the results.
This suits someone who wants thyroid hormones tested alongside iron, key vitamins and inflammation markers in one sitting, for example if fatigue or mood symptoms could have several causes rather than a single thyroid explanation. If you only need the core thyroid hormones without the added extras, Blue Horizon's own smaller thyroid profiles cover TSH, free T3 and free T4 for less. If symptoms are persistent or severe, it is worth speaking to a GP as well.
You can provide a sample at home with a finger-prick kit, or have a venous draw at a clinic or via a nurse home visit; the provider notes that blood for the cortisol marker should ideally be taken between 8am and 10am. Once processed, results cover all 15 markers and are reviewed by a doctor, with turnaround stated at around 1 day.
