About this test

This test looks at eight markers across four areas often linked to persistent tiredness: hs-CRP for inflammation, ferritin, iron, TIBC and transferrin saturation for iron status, TSH and free thyroxine for thyroid function, and vitamin D. Low iron, an underactive thyroid and low vitamin D are all commonly investigated when someone reports ongoing fatigue or brain fog.

There is no named comparison group for this test, so it cannot be benchmarked against specific rivals here. Against the wider set of similarly sized energy and fatigue tests Medichecks and other providers offer, its eight markers and £79 price both compare favourably, with the price sitting around 29% below the roughly £111 median for tests of that size.

It scores well for value for money and for collection convenience, since it can be done at home by finger-prick as well as by clinic or nurse visit, with results in around 3 days. It also scores well on trust signals, reflecting Medichecks' Trustpilot record and its UKAS ISO 15189 partner labs, and on results and follow-up because a doctor reviews every result.

Who is it for?

This suits anyone with ongoing tiredness, low energy or brain fog who wants an initial blood-based check of some of the more common physical causes, such as low iron, low vitamin D or an underactive thyroid, before deciding whether to see a GP. It can also work as a broader first step than a single-marker test if you are not sure which cause to investigate.

If you already suspect a specific cause, such as thyroid trouble alone, a dedicated thyroid panel would give more thyroid detail; this test's thyroid coverage is limited to TSH and free thyroxine, without free T3 or antibodies. There is no named comparison group for this test, so it is not possible to say here whether a specific rival product is cheaper or deeper.

How it works

You can give a sample by at-home finger-prick kit, or have blood drawn at a Medichecks clinic or via a home nurse visit. The lab tests for hs-CRP, ferritin, iron, TIBC, transferrin saturation, TSH, free thyroxine and vitamin D, and a doctor reviews the results before they are released. Medichecks states a turnaround of around 3 days.

Pros & cons

Pros

  • Covers four separate areas linked to fatigue, inflammation, iron status, thyroid function and vitamin D, in one blood draw.
  • Priced around 29% below the roughly £111 median for similarly sized energy and fatigue tests we track.
  • Doctor review is included as standard rather than sold as a paid extra.
  • Sample can be taken at home by finger-prick, without needing a clinic visit.
  • An add-on qFIT test is available to check for hidden gut bleeding as a cause of iron deficiency.

Cons

  • Thyroid coverage is limited to TSH and free thyroxine, without free T3 or thyroid antibodies.
  • No comparison group is listed for this test, so its price and depth cannot be benchmarked against named rivals here.
  • Turnaround is around 3 days from the lab receiving the sample.

Our editorial score

Compare Health Test Score Broad fatigue panel covering iron, thyroid and vitamin D
Editorial confidence: 10.0/10

For £79, this panel checks eight markers across inflammation, iron status, thyroid function and vitamin D, the areas Medichecks link to common causes of fatigue. That is around 29% below the roughly £111 median for similarly sized energy and fatigue tests we track. Thyroid coverage here is limited to TSH and free thyroxine, without free T3, so it is not a full thyroid workup.

Score breakdown

  • Clarity and documentation 8.0/10
