About this test

This test looks at some of the more common contributors to persistent tiredness, including iron status, vitamin B12, vitamin D and thyroid function, across 6 markers in total. These are commonly checked when fatigue has no obvious cause, though the test cannot rule out other explanations and ongoing symptoms are worth discussing with a GP.

We do not have named direct competitors for this exact combination of markers. Against the ten similarly sized energy and fatigue tests we track, its £105 price is close to the £108 median, but its 6 markers place it in only the 38th percentile for depth, meaning most similarly priced tests in this category cover more ground.

value for money is close to average, while clinical depth is below average for tests of this size. Clarity is also held back because the full list of 6 markers is not published, only iron, B12, vitamin D and thyroid function named as examples. Collection is flexible across four methods, and results are reviewed by a doctor within 2 days.

Who is it for?

This suits you if you want a quick check of the most common nutritional and thyroid-related causes of fatigue. If you want a deeper panel, Forth's own Nutricheck test covers 11 markers, including B12 and vitamin D, for £120.

How it works

Collect your sample using an at-home finger-prick kit, Forth's AutoDraw device, a home nurse visit, or a venous draw at a partner clinic. The lab analyses the 6 markers, covering iron, B12, vitamin D and thyroid function, and a doctor reviews your results. Results are typically available within 2 days.
