About this test

TSH, active B12 and vitamin D are three markers commonly checked when investigating fatigue, since an underactive thyroid, low B12 or low vitamin D can each contribute to feeling low on energy. This test covers those three in one sample rather than a wider panel.

We do not hold a named comparison group of direct rivals for this exact test, so there are no specific peers to weigh it against. Within the wider set of seven similarly sized energy and fatigue tests we track, its £74 price is 30% below the £105 median, though its three markers place it in the 13th percentile for depth among those tests, meaning most comparable tests cover more ground.

Value for money and collection convenience both score well: the price sits well under the category median, and the test can be done entirely at home with a finger-prick kit, with results typically back within 2 days. Clinical depth scores lower, reflecting the narrower three-marker scope.

Who is it for?

This suits you if you want a fast, at-home first check on the three markers most commonly linked to fatigue, thyroid function, B12 and vitamin D, and you want results back quickly rather than waiting on a wider workup.

We have no directly comparable test in our data to point you toward as cheaper or deeper, so we cannot make a specific recommendation either way. If your symptoms need a broader investigation, for example including iron status or inflammation markers, a larger panel would cover more ground, at a higher price.

How it works

You can collect a sample yourself at home with a finger-prick kit, or have a venous blood draw at a Medichecks clinic or via a home nurse visit. The lab analyses the sample for TSH, active B12 and vitamin D, and Medichecks states results are typically back within 2 days, with every result reviewed by a doctor.

Pros & cons

Pros

  • Can be done entirely at home with a finger-prick kit
  • Results typically ready within 2 days
  • £74, some 30% below the median for similarly sized energy and fatigue tests we track
  • Every result comes with a doctor's written comment

Cons

  • Only three markers, in the lower range for depth among energy and fatigue tests we track
  • We hold no comparison group for this exact test, so it is not benchmarked against named rivals

Our editorial score

Compare Health Test Score At-home 3-marker energy check, quick but narrow in scope
Editorial confidence: 10.0/10

TSH, active B12 and vitamin D, three common contributors to fatigue, are checked together in this at-home test. At £74 it costs 30% less than the £105 median for similarly sized energy and fatigue tests we track, though its three markers place it toward the lower end for depth in that category. We hold no named comparison group of direct rivals for this exact test.
