Understanding, not just numbers.

A score is not a diagnosis

Reference ranges and composite scores are tools for interpretation. Your medical history, symptoms and clinical assessment matter. Speak to your clinician about decisions or treatment.

Optimal is not the same as Normal.

NHS reference ranges are calculated from the middle 95% of the general population — which includes people who are tired, overweight, sedentary, and mildly unwell. A result within this range means you are not in the bottom 2.5%. That is a low bar.

Functional optimal ranges are calibrated to the values associated with peak physiological performance — the levels at which your thyroid, liver, cardiovascular system, and immune function operate at their best. They are narrower, more demanding, and more informative.

A result can be within NHS range and simultaneously outside the functional optimal range — and that gap often explains symptoms that have no conventional diagnosis.

How composite risk scores are calculated.

A single out-of-range biomarker is a flag. A pattern across multiple biomarkers is a risk signal. Our engine evaluates combinations — not individual values — because that is how physiology actually works.

The four risk tiers

Clinical oversight is built in.

When results meet clinical escalation thresholds, they are flagged before anything else in the report — with specific guidance, the relevant clinical context, and emergency contact information where appropriate. CRITICAL results trigger an immediate clinical alert notification. The patient-facing report and the clinician-facing version use different language — patient language is supportive and clear; clinician language is technically precise and report-ready.

All 32 risk domains.

Each domain is scored independently. Not every domain is included in every panel — coverage depends on the biomarkers measured.
