METABOLIC MEDICINE : VOLUME 1
How to Interpret Your Blood Test Results
A practical guide to reading your own bloodwork the way a functional clinician does — with optimal ranges, pattern recognition, and the methodology to turn numbers into meaning.
Standard reference ranges were never designed to catch what most chronic illness actually looks like.
Most blood tests come back marked "within normal range". That can be technically true and still completely miss the picture.
Standard reference ranges were built around statistical cutoffs for diagnosable disease. They tell you whether you're sick enough to be flagged. They don't tell you whether your body is operating well, whether a deficiency is quietly setting up a problem, or whether a single nutrient is showing up across three or four different markers in a way that points to something specific.
Chronic illness rarely happens like flipping a switch. It's a gradient. Working with optimal ranges, instead of standard ones, lets you see the gradient — and intervene early, when small changes still produce meaningful outcomes.
A working framework for reading bloodwork the way I read it clinically.
This is the same methodology I use in my own practice, written so that you can apply it to your own results.
It covers more than 80 standard and extended markers, each with a functional optimum range, a clear explanation of what the marker reflects, the patterns that are most worth recognising, and the practical levers that move it. Behind that detail sits a simple ten-step process for working through a full set of results: identify what's outside range, look for repetition across markers, recognise the pattern, identify the upstream driver, and decide what to address first.
The guide is structured to be read straight through once, then used as a reference for every retest after that. A pull-out Quick Reference cheat sheet at the back summarises every marker in three columns — optimum range, key flags, and what tends to drive each pattern — so once you've worked through the methodology, you have a permanent reference you can scan in minutes.
What's inside
The guide is organised by panel, so you can read by section or look up a specific marker on a results sheet.
Methylation: B12, holotranscobalamin, serum and red cell folate, B6 (with detailed coverage of the high-B6 pattern that's increasingly common in Australia), homocysteine, vitamin D
Haematology: full red cell and white cell panels including the differential (monocytes, eosinophils, basophils), platelets, and the most informative blood-cell patterns
Glucose and lipids: fasting glucose, insulin, total and HDL cholesterol, triglycerides, and the trig-to-HDL ratio that's often more useful than LDL alone
Advanced lipids: ApoB, Lp(a), and non-HDL cholesterol — including a caveat on what high LDL really means in the absence of inflammation, insulin resistance, or oxidation
Iron studies: iron, transferrin, transferrin saturation, ferritin
Trace minerals: zinc, copper, ceruloplasmin, and the zinc-to-copper ratio (one of the most useful single markers for stress, anxiety, mood, and hormonal patterns)
Thyroid: iodine and selenium as the first stop, then the full panel — TSH, free T4, free T3, reverse T3, TPOAb, TgAb, TBG
Blood chemistry: electrolytes, kidney and liver function, serum and red cell magnesium, calcium, ALP (with both zinc and manganese interpretation)
Inflammation: CRP, ESR
Adrenal function: cortisol with the diurnal context most single readings miss
Sex hormones: complete female and male panels, with timing guidance for accurate testing
Plus a Before You Test checklist (the biotin–thyroid interaction alone is worth the price of the guide), a How to Talk to Your GP section with specific scripts for getting the right tests ordered in Australia, and a Your Action Plan workbook section that turns the methodology into a fillable template you use every retest.
Why this guide
There are plenty of free articles online that will tell you what a single marker means. What they rarely do is teach you how to read a full result sheet as a system.
That's what this guide does. It treats your bloodwork the way I treat a client's results in clinic — as a story being told across panels, not a series of isolated numbers. The patterns matter more than any individual reading, and the methodology you'll learn here is what lets you see those patterns reliably.
Three things that set this guide apart:
The optimal ranges are clinical, not statistical. They reflect what I see consistently in people who feel well, not what's been calculated from a population that includes a lot of people with early disease.
The methodology is the asset. Markers and reference ranges are available everywhere. The ten-step process for moving from numbers to pattern to upstream driver to action is not — that's what years of clinical practice teaches you, and what this guide gives you a structured way to apply.
The Australian context is built in. Units are given in mmol/L with US conversions where relevant. The high-B6 pattern that Australian labs are increasingly flagging is explained in detail, with the cofactor framework that makes sense of it. The low-selenium soil regions are flagged in the selenium section. The GP-conversation section deals specifically with Medicare-rebate constraints. If you've been frustrated reading US-focused functional medicine guides, this is the one that speaks your language.
Who this guide is for
This is written for people who want to understand what their own results mean — and who are comfortable reading something more detailed than a magazine article.
You'll get the most from it if you:
Have results from a recent or upcoming blood test and want to interpret them properly
Have been told everything is "normal" but still don't feel well
Are working with a practitioner and want to understand the bigger picture
Are managing a chronic condition and want to track your own progress between consults
Are a practitioner yourself looking for a structured framework you can recommend to clients
It's deliberately paced. It's not a quick read, and it's not designed to replace clinical advice. It's designed to make you a much better partner in your own care.
About the author
I'm Lou Chalmer, a scientist and integrative natural medicine practitioner based in regional Victoria. I work with clients across Australia and internationally on autoimmune disease, chronic fatigue, hormonal dysregulation, gut dysfunction, and the somatic legacy of long-term stress.
My background spans environmental science, nutrition, genetics, and counselling, with additional training as a certified HeartMath practitioner and as a Level 1 IFS (Internal Family Systems) practitioner through the IFS Institute. My work sits at the intersection of functional nutrition, environmental science, psychoneuroimmunology, and nervous system physiology, and I approach each client through a systems lens rather than by diagnosis alone.
I came to this work through my own experience with autoimmune disease and chronic illness, and I bring both clinical precision and lived understanding to it.
This guide is the first volume in the Metabolic Medicine series — a body of work designed to give people the tools to understand their own physiology properly, without relying on a practitioner to translate every result.

FAQs
Do I need a medical background to understand this guide?
1
No. The guide is written for people without a clinical background, with technical concepts explained in plain language as they come up. You'll need to be comfortable reading something detailed — it's a working reference, not a magazine article — but no prior knowledge is assumed.
Is this guide relevant if I'm outside Australia?
2
Yes. The Australian context (lab unit conventions, the high-B6 pattern, Medicare-rebate quirks) is built in where relevant, but the methodology, optimal ranges, and pattern recognition apply to bloodwork anywhere. Where Australian labs use different units to US labs, both are given.
How is this different from looking up individual markers online?
3
Individual marker lookups tell you what one test means in isolation. This guide teaches you to read a full result sheet as a system — which is the entire methodology I use clinically. The most important question isn't "is this marker abnormal" but "what does the pattern across markers tell me", and that's not something you can Google.
I'm working with a practitioner already. Will this help me?
4
Many people who use this guide are also working with a practitioner. It's designed to make you a better partner in your own care — to understand what's being tested, what the results mean, and what to ask. Several practitioners also use it as a reference recommendation for their clients.
Can I order this as a paperback?
5
A paperback edition is in production. The PDF is currently the only format available directly through this site. The PDF can be read on any device and printed at home if you prefer paper.
Can I get an invoice for tax or claim purposes?
6
Yes. A receipt is sent on purchase. If you need a tax invoice with your details, email me at lou@ecological-nutrition.com.
Is this suitable for tracking my own progress over time?
7
Yes — that's one of its main uses. The workbook section is designed to be filled out each retest, so you build up a record of your own patterns. The Retest Scheduling section tells you what's worth retesting in 4–6 weeks, 8–12 weeks, 3–4 months, and annually.
