How tests are
scored.

A lab "normal range" is wide enough to include people who are sick. We score against three bands — optimal, within range, and attention — calibrated to age, sex, and population studies, then read in the context of your last quarter's numbers and your current protocol.

01
Three bands

Three colours, not five.

We don't grade you A through F. We tell you where the number is, what we'd like it to be, and what we're doing about it.
— BAND 01

Optimal.

Within the tighter range we'd like to see for a member of your age and sex, with your goals. Most markers move into this band by the second or third quarter on protocol.

  • 01Within YOD optimal range (narrower than lab "normal")
  • 02No protocol change indicated
  • 03We watch for trend, not adjust
— BAND 02

Within range.

Inside conventional lab "normal" but outside our optimal range. We monitor, may discuss, and revisit at the next re-draw. Not flagged as urgent.

  • 01Inside conventional lab "normal" reference range
  • 02Outside YOD optimal
  • 03Watch, revisit at next quarter
— BAND 03

Attention.

Outside conventional lab "normal" — or trending toward it at a rate we don't like. We discuss this on the sit-down, write it into your letter, and most often modify the protocol.

  • 01Outside conventional lab "normal"
  • 02Or trending out at a rate that warrants action
  • 03Protocol typically revised
02
— ONE ANONYMISED EXAMPLE

A single member,
seven markers.

From a Q1 → Q2 recheck.

Lipid + metabolic · Q2 recheck · age 38 M

LDL-C96 mg/dL

Within range

ATTENTION: hsCRP. We'll revisit with EPA loading + dental review; recheck in six weeks rather than next quarter.

Read by a clinician, not a flag.

Every band has context. Every flag has a person reading it. That's the entire difference between a wellness app and a clinic.
