About this test

This panel looks at 23 markers across cholesterol, blood sugar, hormones (including testosterone and oestradiol), thyroid, liver, iron status and inflammation, aimed at people whose weight has not responded to diet and lifestyle changes and who want to check for an underlying hormonal or thyroid cause. It groups together markers that would otherwise need several separate tests.

Against the other tests in its comparison group, this one comes out ahead on depth: 23 markers against a group median of 18, and more than any of the specific peers we track, including Blue Horizon Medicals' 20-marker Fingerprick Wellman and Wellwoman tests. On price it is also competitive, at £107 against a £113 group median, roughly 5% cheaper, which is a large part of why it scores well overall.

Where it loses some ground is collection convenience: you need a venous draw at a clinic or a home nurse visit rather than an at-home finger-prick kit, unlike some cheaper peers such as Better2Know's nurse kits. Trust and results scores are both strong, reflecting Medichecks' Trustpilot rating, lab accreditation and the doctor's comment included with every result.

Who is it for?

This suits someone who has been struggling to lose weight despite diet and lifestyle changes and wants to check for a hormonal, thyroid or metabolic cause before going further. If cost is the priority and you need fewer markers, Monitor My Health's Essential Health Screen covers 9 markers for £49, considerably less than this test, though with much less depth. For genuine breadth at a similar or lower price, this is one of the stronger options in its comparison group.

How it works

This is a blood test. You can have your sample taken at a Medichecks in-store clinic, via a home nurse visit, or as a venous draw at a clinic; there is no at-home finger-prick option for this test. Once your sample reaches the lab, results are typically ready in around 4 days, and every result includes a doctor's written comment.

Pros & cons

Pros

  • Covers 23 markers, more biomarkers than any of the other tests in its comparison group.
  • Priced around 5% below the £113 median for its comparison group.
  • Results are typically back in around 4 days, faster than many broader panels.
  • A doctor reviews and comments on your results, included as standard.

Cons

  • No at-home finger-prick option; a clinic visit or nurse callout is required.
  • Costs more upfront than narrower panels such as Monitor My Health's 9-marker Essential Health Screen at £49.

Our editorial score

Compare Health Test Score Above-average depth for a below-median price in its group
Editorial confidence: 10.0/10

This 23-marker panel costs £107, slightly below the £113 median for its comparison group, while covering more markers than the 18-marker group average and every peer we list. It includes cholesterol, hormone, thyroid, liver and iron markers relevant to weight gain, reviewed by a doctor with results in around 4 days. The main trade-off is that it still needs a clinic visit or nurse callout rather than an at-home kit.
