About this test

This panel looks for several of the more common, testable physical causes of tiredness: a full blood count to check for anaemia, iron and ferritin levels, thyroid function through TSH and free T4, and vitamin D. Low levels in any of these areas are frequently linked to fatigue, though tiredness can also have causes this panel does not cover, so it is best used alongside a conversation with a GP rather than as a standalone answer.

There is no named comparison group on record for this test, so it is scored against the wider set of similarly focused tests we track. On that basis its 18 markers place it in the 88th percentile for depth, and its £99 price sits about 8% below the £108 median for similarly sized fatigue panels.

Collection convenience is limited to a clinic venous draw or paid home visit, and trust signals reflect the provider's CQC registration and doctor-reviewed report as standard.

Who is it for?

This suits people experiencing ongoing tiredness who want a broad first pass at common physical causes, ideally alongside GP advice rather than instead of it. If you already suspect a single specific cause, such as low vitamin D, a single-marker test such as London Medical Laboratory's own Vitamin D test (£49) is a cheaper way to check.

How it works

This is a blood test taken by venous draw at a partner clinic (£35) or a phlebotomist home visit (£80); it is not available as an at-home finger-prick kit. Results are typically back within a day and are reviewed by a doctor.

Pros & cons

Pros

18 biomarkers, in the 88th percentile for depth among fatigue tests we track
Combines full blood count, iron studies, vitamin D and thyroid function in one draw
About 8% cheaper than the typical price for similarly sized fatigue panels
Results reviewed by a doctor and typically back within a day

Cons

No finger-prick option; requires a clinic visit or paid home visit
If you only suspect one specific cause, a single-marker test works out cheaper

Compare Health Test Score Fatigue panel in the 88th percentile for depth

Editorial confidence: 10.0/10

This £99 panel checks 18 biomarkers, placing it in the 88th percentile for depth among the energy and fatigue tests we track, and it prices about 8% below the £108 median for similarly sized fatigue panels. It requires a venous blood draw rather than a finger-prick sample.

Score breakdown

Clarity and documentation 9.0/10

The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
Clinical depth 9.8/10

18 biomarkers, placing it in the 88th percentile of energy fatigue tests we track.
Collection convenience 9.0/10

A finger-prick sample you take at home; with a venous or clinic option as well; results in around 1 days, well ahead of the energy fatigue norm of 3.
Results and follow-up 7.0/10

Results are reviewed by a doctor; the provider does not describe the report format.
Trust signals 6.5/10

No Trustpilot rating on record; CQC registered; doctor review as standard.
Value for money 6.9/10

£99.00 against a median of £108.00 for the 6 similarly sized energy fatigue tests we track (-8%).
