Functional blood analysis
Looking "normal" doesn't always mean feeling your best. Let's look deeper at what your blood is really telling you.
Told your bloods are normal, but you still don't feel right?
Blood testing can reveal how your body is functioning beneath the surface, often showing patterns and imbalances long before they become more significant concerns.
Many people are told their results are "normal" while still living with symptoms like:
Built to detect disease
- Compares your results to broad population averages
- Flags only when a marker falls outside the "normal" range
- Designed to identify and manage illness
- Rarely explains why you still feel unwell
Built to optimise health
- Assesses patterns, trends and optimal functional ranges
- Looks at the relationships between biomarkers
- Spots early signs of dysfunction before they progress
- Focused on prevention and helping you feel your best
Why blood analysis matters
Instead of relying on guesswork, your blood work offers a more personalised, strategic starting point for nutrition, supplementation, lifestyle and long-term health. It can give insight into areas such as:
A deeper look beneath the surface
Functional blood analysis is a powerful tool for understanding nutrition, digestion, gut health, hormones, metabolism, energy and inflammation, because your blood markers hold clues about nutrient status, stress, immune function, blood sugar and gut health.
Red blood cells carry oxygen around the body. Low counts may suggest anaemia, often linked to iron or B12 deficiency, which can stem from diet or gut malabsorption.
White blood cells drive your immune response. Unusual counts can point to infection, dysbiosis or immune issues, and are often connected to gut health, since much of the immune system lives in the gut.
Platelets are essential for clotting and can be affected by nutritional deficiencies. Haemoglobin and haematocrit reflect how well your blood carries oxygen, which nutrition strongly influences.
Liver markers such as ALT, AST and bilirubin reflect liver health, which is closely tied to digestion and nutrient processing.
Kidney markers like creatinine and BUN reflect kidney health, influenced by diet, hydration and metabolism.
Electrolytes (sodium, potassium, chloride and bicarbonate) are crucial for cellular function and shaped by diet and gut absorption.
Evaluates total cholesterol, LDL, HDL and triglycerides. Imbalances often relate to dietary choices, and these markers help assess hormones, bile acids and antioxidants, which can indirectly affect gut health.
Fasting glucose and HbA1c help assess blood sugar regulation. These are directly influenced by diet and have a profound impact on overall health, including the gut.
Thyroid hormones (T3, T4) and TSH can reveal an under- or over-active thyroid. Thyroid imbalances affect metabolism, weight and digestion, making them important for a nutritional picture.
Measures specific vitamins (like B12 and D), minerals (like iron and calcium) and antioxidants. Deficiencies or excesses can indicate dietary imbalances and may point to issues with gut absorption.
I don't rely on conventional reference ranges alone, as these are based on broad population averages rather than optimal health. Functional analysis assesses patterns, trends and optimal ranges to understand how your body may be functioning beneath the surface.
Is this different from my doctor's test?
Yes, and the difference is worth understanding. Getting a blood test is the easy part. Your GP or a private clinic draws the blood and checks each marker against standard reference ranges, which exist to flag disease. If nothing is flagged, you're told everything looks "normal", even when you clearly don't feel it.
Functional blood analysis is the interpretation, not the test itself. I take those same results and read them against optimal ranges, looking at the patterns and relationships between markers, to understand what may be driving your symptoms and how to support your body, long before anything would show up as a medical problem.
In short: your doctor tells you whether you're ill. Functional analysis helps you understand how to feel and function at your best.
Your body tells a story
Your symptoms, lifestyle, stress, digestion, nutrition, health history and blood markers all offer clues about how your body is functioning. Rather than a generic, one-size-fits-all approach, I use blood analysis as part of a broader root-cause assessment to build a strategy tailored to you.
The goal is never simply symptom management. It's about understanding your body more deeply, identifying potential dysfunction earlier, and creating a stronger foundation for long-term health.
No two stories are the same
So your interpretation, and the plan that follows, is built entirely around you.
