A normal range shows where most people's results fall. It doesn't always tell you whether you are well supplied. The guide explains ten blood markers and how to read them together.
- The 10 markers explained: what they show, how solid the numbers are and what you can do yourself, plus a symptom map
- Lab ranges and coaching reference points, colour-coded: lab ranges and guidelines on one side, reference points from my coaching on the other, each with a note on the evidence
- Printable list for your blood test: for your GP, your gynaecologist or an independent lab, with notes on how to prepare
- Example page with three markers: how ferritin, hsCRP and HbA1c look different together than each value on its own
- 39 sources: studies, guidelines and lab references, all listed in the guide

Why this guide
Everything within the normal range, and you are still tired?
You feel tired even though you sleep enough. You find it hard to concentrate. You have a blood test, and the result comes back: everything within the normal range.
A standard blood test is a good tool. It shows whether there is a disease or whether something has gone acutely wrong. What it often doesn't show is whether your body is well supplied. And some markers, such as ApoB, Lp(a) or homocysteine, are usually not part of the standard panel.
The guide explains ten blood markers: what they show, how solid the numbers are and what you can do yourself. Lab ranges and coaching reference points are kept clearly apart. An example page shows how to read several values together. This helps you discuss your results with your doctor in a focused way.
It does not replace medical diagnosis or individual care, but it gives you the knowledge to ask the right questions.
