What's measured
10 biomarkers in this test
Every marker below is read against optimal ranges — not just the lab reference band — and explained by a clinician on your results call.
Vitamins
4 markersActive Vitamin B12
pmol/LThe portion of B12 your cells can actually use.
Why it matters
More accurate than total B12, which can look normal while the usable fraction is low.
Vitamin D
nmol/LThe vitamin your skin makes from sunlight, essential for bone, muscle and immune function.
Why it matters
Deficiency is near-universal in northern Europe through winter, and among the easiest deficiencies to correct.
Vitamin B9 (Folate)
nmol/LVitamin B9, needed to build DNA and red blood cells.
Why it matters
Works together with B12 — treating one without checking the other can mask a serious deficiency.
Minerals
6 markersMagnesium
mmol/LA mineral involved in muscle function, nerve signalling and energy production.
Why it matters
Low magnesium contributes to cramps, palpitations and poor sleep, and often accompanies high sugar intake.
Sodium
mmol/LThe main electrolyte controlling fluid balance in your body.
Why it matters
Abnormal levels affect blood pressure and brain function, and can flag kidney or hormonal problems.
Calcium
mmol/LThe mineral behind bone strength, muscle contraction and nerve signalling.
Why it matters
Tightly controlled by your body, so abnormal levels usually point to a parathyroid, kidney or vitamin D problem.
Potassium
mmol/LAn electrolyte essential for heart rhythm and muscle function.
Why it matters
Both high and low levels affect the heart directly, which makes it one of the more urgent results.
Zinc
µmol/LAn essential trace mineral used by hundreds of enzymes, immunity and wound healing.
Why it matters
Deficiency shows up as poor immunity, slow healing and taste changes, and is common in vegetarian diets.
Ferritin
µg/LYour body's iron store — the protein that holds iron until it is needed.
Why it matters
The first thing to fall when iron runs low, often long before haemoglobin drops. A common and very treatable cause of fatigue.
