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 bundle combines a full thyroid blood panel with a DNA thyroid-genetics swab test and an IgG antibody test against 134 foods and drinks. It suits people who want to look at thyroid symptoms from several angles, including genetics and possible food reactions, in a single order.
14 biomarkers as listed by Blue Horizon Medicals, of 155 in total.
This is a bundle of three separate assessments rather than a single blood panel: the Thyroid Premium Platinum profile (thyroid hormones, thyroid antibodies, reverse T3, iron status, key vitamins, cortisol, magnesium, CRP and HbA1c), a DNA swab test looking at 10 variations across 8 genes linked to thyroid function, and an IgG antibody test against 134 foods and drinks. Together they cover 155 markers, far more than any single thyroid blood test in the catalogue.
There is no named comparison group for a bundle of this kind, and the value for money scoring notes there is nothing directly comparable to benchmark the £551.25 cost against. What is clear from the marker count alone is that this places in the 100th percentile of thyroid tests we track, reflecting the scale of combining three distinct assessments into one order.
It scores at the top of the range for clinical depth given the sheer number of markers, and well for how clearly the listing sets out what is included. It scores lower on collection convenience, since it needs a venous draw at a clinic or a nurse home visit and results take around 30 days, the longest turnaround of Blue Horizon's thyroid range.
This suits someone who wants to investigate thyroid symptoms as thoroughly as possible in one order, including a genetic component and a look at food reactions, and who is comfortable with a longer wait and a higher price than a standard thyroid panel. If you only need the blood-based thyroid markers without the DNA and food-intolerance elements, Blue Horizon's Thyroid Premium Platinum profile covers that part of the bundle on its own for £199.25.
Collection is by venous draw at a clinic or with a nurse home visit for the blood component; the provider recommends taking the sample between 8am and 10am for a more reliable cortisol reading. The bundle also includes a DNA swab and an IgG antibody test against a food and drink panel. A doctor reviews the results, with turnaround stated at around 30 days for the full bundle.
This is Blue Horizon's largest thyroid-related order, bundling the Thyroid Premium Platinum blood panel with a DNA swab looking at gene variants linked to thyroid function and an IgG antibody test against 134 foods and drinks, for 155 markers in total. At £551.25, the fact sheet notes there are no directly comparable tests to benchmark the price against. Turnaround is longer too, at around 30 days, and it needs a venous draw at a clinic or nurse visit rather than an at-home kit.
The listing publishes a detailed description, some of the biomarkers by name, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
