About this test

The Essential Vitamin and Minerals Blood Test measures selenium, magnesium, folate, ferritin, zinc, active vitamin B12, calcium and vitamin D. This is a wider combination than most single-nutrient tests, adding trace minerals such as magnesium, selenium and zinc that are less commonly included in basic vitamin panels.

Its 8 markers place it in the 87th percentile among the vitamin tests we track, but at £199 it costs about 124% more than the £89 median for similarly sized vitamin panels. There is no direct comparison group of equivalent combined panels in our data to weigh it against more precisely.

This gap between strong Clinical Depth and weak value for money pulls its overall score down. Collection Convenience also scores lower than Selph's finger-prick tests, since this panel requires a venous blood draw at a clinic or with a nurse rather than an at-home finger-prick kit, and results take 4 to 5 days rather than 1 to 2.

Who is it for?

This suits you if you specifically want trace minerals such as magnesium, selenium and zinc tested alongside the more common vitamin D, B12 and ferritin, and you are comfortable arranging a venous blood draw. If you only need one or two of these nutrients checked, Selph's Iron, Vitamin D & B12 Deficiency Blood Test (£79) covers three of the same markers by finger-prick for considerably less.

How it works

This test requires a venous blood draw rather than a finger-prick; you can visit a partner clinic, book a nurse to draw blood at home or work, or arrange your own venous draw. A Selph doctor reviews your results and provides a written report, typically within 4 to 5 days.
