About this test

This screen measures eight minerals directly within your blood cells, rather than in serum: potassium, magnesium, calcium, manganese, zinc, copper, selenium and chromium. Whole-blood measurement is intended to give a more stable, longer-term picture of mineral status than a single serum sample, which can be affected by recent diet or hydration.

On our site this panel is recorded as a single combined biomarker, which places it in the 31st percentile for clinical depth among the vitamins and minerals tests we track, even though it reports on eight separate minerals. There is no comparison group recorded for pricing it against direct competitors, but at £350 it is priced 312% above the £85 median for similarly sized tests in the category.

The listing is detailed on what is measured and how collection works. It scores lower on collection convenience, since results take up to 5 working days, and on results and follow-up, since results are not reviewed by a doctor as standard.

Who is it for?

This suits someone who wants a broad, longer-term view of their mineral status across eight key minerals in one test, rather than checking them individually. It may be useful if you have symptoms such as persistent fatigue, muscle cramps or slow wound healing that could relate to a mineral imbalance.

If you only need to check one or two specific minerals, a smaller, cheaper panel focused on those markers is likely to be more cost-effective than this broad £350 screen.

How it works

A blood sample is taken by venous draw, either at a Better2Know clinic or from a visiting nurse. The sample is analysed in the laboratory for whole-blood levels of potassium, magnesium, calcium, manganese, zinc, copper, selenium and chromium. Results are typically available within 5 working days. The provider does not state that results are reviewed by a doctor as standard.

Pros & cons

Pros

  • Covers eight minerals in one whole-blood panel rather than testing each separately.
  • Whole-blood measurement gives a longer-term picture than a single serum snapshot.
  • A home nurse visit is available instead of attending a clinic.

Cons

  • At £350, this costs over four times the £85 median for similarly sized vitamins tests we track.
  • Results take up to 5 working days.
  • No standard doctor review of your mineral results.
