About this test

This panel builds on the core thyroid hormones and antibodies with reverse T3, a marker the provider notes is used by functional and naturopathic practitioners, plus a fuller iron profile (iron, ferritin, TIBC, UIBC and transferrin saturation), vitamin D, active B12, folate, cortisol, magnesium, CRP and HbA1c, commonly used to assess blood sugar control.

There is no comparison group listed for this exact combination and no directly comparable test in the value for money scoring, so it is not possible to say here whether £199.25 is expensive or reasonable next to specific rivals. What can be said is that its 18 markers place it in the 98th percentile for marker count among the thyroid tests we track.

It scores at the top of the range for clinical depth given its marker count, and well for how clearly the listing is documented. It loses marks on collection convenience because it requires a venous draw at a clinic, with a home nurse visit as the only alternative to travelling, and results take around 20 days rather than the next-day turnaround of Blue Horizon's other thyroid profiles.

Who is it for?

This suits someone who wants thyroid hormones, antibodies, iron status, key vitamins, blood sugar and inflammation checked in one visit, and who does not mind a venous draw and a longer wait for results. If you want the same core thyroid and antibody markers with a faster turnaround and an at-home option, Blue Horizon's own Thyroid Premium Gold profile covers 12 of the same areas with results in around a day.

How it works

Collection is by venous draw only, either at a clinic or with a nurse home visit; there is no at-home finger-prick option for this panel. The lab processes all 18 markers, a doctor reviews the results, and turnaround is stated at around 20 days.

Pros & cons

Pros

  • Covers 18 markers in one test, including reverse T3, a fuller iron profile and HbA1c.
  • Places in the 98th percentile for marker count among the thyroid tests we track.
  • Results are reviewed by a doctor.
  • Listing clearly sets out every marker, the sample type and the turnaround.

Cons

  • No at-home collection option; requires a venous draw at a clinic or a nurse visit.
  • Turnaround is around 20 days, much slower than Blue Horizon's other thyroid profiles.
  • No comparable tests listed to check whether £199.25 represents good value.

Our editorial score

Compare Health Test Score 18-marker thyroid panel adding reverse T3 and HbA1c
Editorial confidence: 10.0/10

This 18-marker test combines the core thyroid hormones and antibodies with reverse T3, iron studies, vitamin D, active B12, folate, HbA1c and CRP. At £199.25, the fact sheet notes there are no directly comparable tests to benchmark the price against yet. The main trade-off is collection: it needs a venous draw at a clinic or nurse home visit, with results taking around 20 days.

Score breakdown

  • Clarity and documentation 9.0/10

  • Collection convenience 8.0/10
