Health markers · the library
What your markers actually mean — checked before it’s published.
Plain-language notes on each blood marker: what it is, why it matters, and the thing most people miss — the healthy range isn’t one number; it shifts with your age and differs from person to person. A note only goes up once a clinician has reviewed it, so what you read here you can trust.
◆ In clinical review
The first notes are with a clinician.
Nothing is published here yet — and that’s the point. Every note is written, then checked by a clinician before it goes up. The library fills as each marker clears review.
